The Gods of Atlantis

The Adirondack Mountains, New York State, present day

J ack switched the headlamps of the rented SUV to high beam as he turned off the paved road into the gravel lane that led to the farm.

He had driven out of Syracuse airport in upstate New York a little over two hours before, having flown there overnight from Vancouver with Costas in the IMU Embraer. The aircraft had gone on from Syracuse to Bermuda to take Costas to Seaquest II, which was standing off the island ready to sail south towards the Caribbean. It was scheduled to return to Syracuse for Jack later that day, and meanwhile all of Jack’s attention was on the text message Mikhail had sent him the evening before about his research into U-boat sightings in the Caribbean in the weeks following the Nazi surrender in May 1945. Everything they had found out so far, from Frau Hoffman, from the Ahnenerbe man Schoenberg in British Columbia, had pointed them to the Caribbean, to a place where Himmler’s men had apparently built a secret installation at the site of an extraordinary landfall dating to more than seven thousand years before. But that still left thousands of square miles of ocean to explore, with numerous uncharted islets and reefs. Jack hoped against hope that Mikhail would provide a lead, something that would allow them to pinpoint a location. All the time Saumerre’s men would be closing in, watching and waiting, their patience wearing thin. Jack knew that the gamble he had taken to keep Saumerre from ordering his men to attack would only succeed if he and Costas arrived at the site very soon. What he found out here today from Mikhail might prove decisive.

He stopped the vehicle at the top of the lane and switched off the engine, then opened the door and stepped out to enjoy a moment of silence. The first light of dawn revealed wisps of mist that hung between the dense line of cedars on either side of the lane. The forest extended off in all directions, rising up the foothills of the Adirondacks, which formed dark ridges on either side. He remembered the preternatural quiet of this place, more than twenty miles from the nearest town and separated from other farms by dense tracts of forest. Somewhere in the distance he heard the yipping and howling of a pack of eastern coyotes, an eerie sound that sent a shiver up his spine. During the week he had spent here six months ago, he had hiked with Mikhail and Petra all over the surrounding Adirondack hills, the three of them struggling to keep up with Rebecca. He took a deep breath, savouring the chill morning air. Rebecca. She was here too, with Jeremy. She knew he was coming, but he had hoped to arrive before she was up. He got back into the SUV and switched on the engine, looking through the tunnel of light created by the headlamps down the lane. The house lay in a clearing more than a quarter of a mile ahead, surrounded by irregular fields hacked out of the forest by pioneer settlers more than two centuries before, when this had been Iroquois territory.

He edged the vehicle forward, hearing the tyres crunch on the gravel. After about two hundred metres he passed over a small creek with swampy ponds on either side, and saw the dark shadow of the barn ahead. Any hope of a quiet arrival was shattered by the raucous barking of the pair of German shepherds that Mikhail kept in a fenced compound beside the house; then a cluster of motion-sensor halogen lights lit him up. He accelerated to the end of the lane between the barn and the house and switched off the engine, taking his fleece and getting out just as a figure appeared out of the gloom holding a rifle muzzle-down, like a soldier. Jack extended his hand. ‘Mikhail. Good to see you.’

‘Jack.’ Mikhail took his hand from the rifle grip and shook Jack’s, smiling warmly at him. He was about Jack’s age, a few inches shorter, with cropped grey hair, a Russian whose features were more Viking than Slavic, and he spoke English with a slight accent.

Jack pointed at the rifle, a British Lee-Enfield. 303 that he knew Mikhail used for deer hunting. ‘Have you had any trouble?’

Mikhail shook his head. ‘Nothing yet. But we treat every arrival as suspicious. Your security chief Ben Kershaw and the British secret service guy, John, have both been here for the past two nights, ever since Rebecca and Jeremy arrived. One of them is always on the perimeter near the road. John does the day shift, Ben the night. Ben was probably within sniffing distance of you at the head of the lane, but I know he wouldn’t reveal himself even to you.’

‘When he was in the SAS in the 1980s, that’s what they got good at,’ Jack said. ‘Squatting in hedgerows in South Armagh in Northern Ireland for hours and days on end, waiting for IRA terrorists.’

‘Jeremy’s making breakfast. I expect you’ll need some. I’ve got some really exciting stuff to show you, Jack. It could be just what you want.’ They walked past the dogs, both quiet now, and then up the path to the house, where Mikhail opened the screen door and ushered Jack in, closing it and locking the main door behind them. They went through a room that had once been the pioneer log cabin and then into a spacious modern extension, up a wide staircase to a large open-concept pentagonal room that served as a living area as well as Mikhail’s study. On every side above bookcases were wide windows that gave an unimpeded view over the farm up to the edge of the field clearings, now visible in the light of dawn. Mikhail walked a few steps down to a sunken sitting area in the centre of the room, with easy chairs surrounding a rustic table made from sections of hardwood trunk. He opened the bolt of the rifle, extracted the round that had been in the chamber and pressed it back into the magazine, then closed the bolt over the rounds, placing the rifle on the table beside several other guns. He and Jack sat down opposite each other as another figure appeared up the stairway. Jeremy looked half asleep, with dishevelled hair, and he wore a sweater and jeans that looked as if they had just been thrown on, but he was carrying a tray of coffee mugs and croissants.

‘Grub’s up,’ he said, putting the tray on the table and grinning at Jack. ‘Isn’t that what your old seadog grandfather used to say?’

Jack took a coffee and smiled. ‘Hello, Jeremy. Is Rebecca awake?’

‘I’ll knock on her door if you want.’

‘No,’ Jack said. ‘It’s only just dawn, and she is still a teenager.’

Jeremy grinned again. ‘As you keep reminding me. She can’t wait to see you.’

‘Let’s see what Mikhail has to say first.’ Jack leaned forward, took a gulp of coffee and put the mug down on the table. He pointed to where the Lee-Enfield lay beside three other weapons, a Ruger 10/22 semi-automatic rifle, a Beretta side-by-side 12-gauge shotgun and a revolver, alongside a cardboard box filled with ammunition. ‘That’s quite an arsenal.’

‘Ben and John are both carrying Glocks,’ Mikhail said. ‘These are just my farm guns, for hunting and personal defence. I know how good you are with the Lee-Enfield, from shooting with you here last year, but I’ve only just sighted it in for new ammunition I’ve reloaded myself so I’ll take that. If the need arises, Rebecca has the shotgun and Jeremy the Ruger.’

Jack looked questioningly at Jeremy. ‘Have you done much shooting?’

‘I grew up in rural Vermont, where just about every boy I knew had a 10/22. You just have to know the limitations of the. 22, even the hyper-velocity rounds. For anything bigger than a squirrel, that means less than fifty yards and always a head shot. But with the right shot placement, that rifle could kill a man instantly.’

There was a rustle from a corner of the room and Rebecca appeared bleary-eyed around a door, her long dark hair hanging over an oversized T-shirt. She gave a small wave, then shut the door again. Jeremy turned back to Jack. ‘I know what you’re asking. I haven’t pulled a gun on a man before, but I’ll do what it takes. We’ve got assets to protect.’

Jack reached over and picked up the revolver, a heavy break-top Webley. ‘So it looks as if this is mine.’

‘It’s an old British service revolver,’ Mikhail said. ‘A lot of Webleys were sold as surplus into the States in the fifties and sixties. It’s a man-stopper,. 455 calibre, designed to put down fanatical tribesmen on the Afghan frontier. It’s my home defence weapon.’

Jack spun the cylinder, then cupped his hands around the grip and aimed the pistol. ‘Scott Macalister has one of these, and I’ve practised with it from the ship.’ He pressed the lever on the receiver with his right thumb and broke the pistol open, pivoting the barrel and cylinder forward and letting the ejector snap out and fall back again. He reached over to the cardboard box and took out a container of. 455 ammunition, opened it and loaded six cartridges into the cylinder, leaving the pistol broken open and laying it back on the table. ‘If Saumerre’s men do try to attack, what’s the drill?’

Mikhail sprang up from his chair and went up to the window on the opposite side of the house from the barn, gesturing for Jack and Jeremy to follow. Jack mounted the stairs and stood beside him, looking over the lush green winter wheat that carpeted the field towards the pine and maple trees bordering the forest beyond. Mikhail opened the mosquito screen on the window, took a compact laser rangefinder from the ledge below and peered through it, finding a target and holding the rangefinder steady with both hands while he pressed the activator on the top. ‘That large dead pine at the end of the field is three hundred and twelve metres away,’ he murmured. ‘That’s the furthest line-of-sight distance in any direction from the house.’ He took down the rangefinder and pointed to a large aerial photograph of the farm pinned to the wall beside the window, showing the three main fields extending off from the buildings like fingers penetrating the forest. ‘It’s all near enough for me to shoot using the battle sights on the Lee-Enfield without any need for range adjustment.’ He looked back, scanning the far edge of the field for a moment, and then pulled shut the mosquito screen. ‘It’s been done before,’ he said, looking at Jack. ‘During the war of 1812, the place withstood a combined British and Iroquois attack. The farmer and his boys only had flintlock longrifles, but it did the trick.’

‘Should one of us be standing lookout?’ Jeremy said.

Mikhail shook his head. ‘No need until we’re certain there’s a threat. Best to rest and keep alert. At the moment Ben is the first line of defence, and the dogs provide an early-warning system. I built the pen so they have a full run around the house. They’re very territorial and want to attack anything that intrudes on this place. They’ll let us know.’

Jack gestured at a spotting scope on a tripod beside the window. ‘It looks as if you designed this room as a defensive outpost.’

Mikhail gave a wry smile. ‘I’m a pretty serious birder. Rebecca’s probably told you all about it. I used to drag her along to all kinds of places to spend hours sitting beside some swamp at migration time. When we bought this farm, the house was derelict and I had this room built as part of an extension, custom-designed as an observatory.’

‘And a place to write your books. I envy you that.’

Mikhail paused. ‘There’s another reason for the design of this room, the open-plan concept with the continuous window. Even when I’m absorbed in writing, I’m not comfortable in a room where I’m not aware of my surroundings. I can’t sleep unless the windows are open. It’s a small legacy of war.’

Jeremy eyed him cautiously. ‘You were in Afghanistan during the Soviet war, weren’t you? Before you defected? Rebecca told me, but I know you don’t like it spread about. Plenty of people here haven’t forgotten the Cold War and still think of the Russians as the enemy.’

Mikhail walked over and opened the top drawer of a small wooden chest beside the sofa. He took out two badges and tossed them on the sheepskin carpet on the floor in front of them. One was a hammer-and-sickle design within a star surrounded by golden sheaves of wheat; the other was a red-enamel pentagonal star containing a white-metal image of a Soviet soldier holding a rifle. He looked at them ruefully. ‘The Order of the Red Banner and the Order of the Red Star. They dished those out to everyone who fought in the battle for Hill 3234, to the men who survived and the families of the men who died. I was an intelligence officer attached to the 345th Independent Guards Airborne Regiment. We were ordered to occupy a nameless ridge 3,234 metres high overlooking the road from Gardez to Khost near the Pakistan frontier. It was the night of the seventh of January 1988. A single reduced company of thirty-seven men fought off waves of attacks by hundreds of mujahideen all night long. By the time we were relieved, we’d suffered thirty-four casualties.’

‘And you survived unscathed?’ Jeremy asked.

Mikhail pulled up his left sleeve, revealing an ugly scar under his bicep. ‘You may have noticed that I can’t really use all the fingers of my left hand. The mujahideen who shot me was using an old British service rifle, a Lee-Enfield. Somehow having one of those rifles here and being in control of it helps me to deal with the pain. He came right up to our perimeter and I killed him with a grenade.’

‘That’s one less Taliban today,’ Jeremy murmured.

‘Maybe. But if we hadn’t invaded Afghanistan in 1979, there’d have been no mujahideen and then maybe no Taliban and no al-Qaeda. The only thing I can be sure of is that I fought in the last campaign of the Cold War and that our defeat brought about what I so desperately wanted, the collapse of the Soviet Union. Just like Korea and Vietnam and numerous other proxy conflicts between communism and the West, fighting mujahideen on the Afghan frontier served as a pressure-relief valve that kept the prospect of nuclear annihilation at bay. That’s the way I see it as a historian, though as a soldier you only see yourself and your mates. Without the breakdown in the Soviet security system that was precipitated by the Afghan War, Petra and I might never have defected and I wouldn’t be a professor of history in the United States today.’

‘And Rebecca wouldn’t have had such marvellous foster-parents,’ Jack said.

Mikhail walked around and peered out of the window facing the driveway. ‘The difference between here and Hill 3234 is that we held a mountain ridge with three-hundred-and-sixty-degree visibility down into the surrounding valleys. What nearly finished us was the sheer force of mujahideen numbers, as well as the rocky terrain that allowed them easy concealment as they came up the slopes, and the limitations of our weapons and ammunition supply. What mainly concerns me here are the two places where the forest comes within seventy metres of the house. But let’s leave that to Ben and the dogs. I want to show you what I found in the archive, Jack.’

‘Good. The Embraer’s returning to Syracuse for me this afternoon.’

They walked down the steps and sat around the table. Mikhail picked up a large manila envelope from beside the guns and slid out a sheaf of papers that looked like scanned documents. He peered at Jack, his eyes alight with excitement. ‘You asked me for two things. First, to try to get the inside story on the discovery of those crates of Schliemann’s treasures in Moscow in the 1980s, the artefacts from Troy taken by the Russians in 1945 from Berlin. My contact in Moscow is looking into it, and it’s very promising. She says the curator who found the crates also discovered a package of documents with it, German military order books that the Russian soldiers who seized them must have shoved into one of the crates and then forgotten. She thinks they still exist in the museum store, and she’s on the trail.’

‘Hoffman’s diary,’ Jack murmured. ‘Frau Hoffman told us he’d mentioned it to her during their brief final encounter before he embarked on the U-boat, that he’d left it with the crates in the Zoo tower for the Soviet intelligence people to find. He told her it contained everything he knew about the final months of the Third Reich.’

‘That could be explosive,’ Jeremy said.

‘As soon as we’re done here and Rebecca’s safely in your hands, I’m on a plane to Moscow,’ Mikhail said. ‘This kind of thing comes to a historian once in a lifetime.’

‘And the second thing?’ Jack said. ‘The reason why I’m here?’

Mikhail leaned forward. ‘You asked me to look for any reports of U-boat sightings in the Caribbean after the German surrender on the eighth of May 1945, for anything unexplained or odd. At first I was sceptical. The Caribbean was a major area of operations for long-range U-boats in 1942 and 1943, with many merchantmen torpedoed and at least a dozen subs sunk in the area by Allied aircraft and ships. But the last recorded attacks on Allied shipping in the Caribbean were in July 1944, and the last known U-boat patrol there ended the following month. Most reports of sightings after that can be put down to jittery coastguards, seeing dark shapes on the sea at night. But it’s true there has always been a big question mark over the final weeks of the war. There are some who believe that U-boats secretly sailed through the Caribbean on the way to Costa Rica and Brazil and other south American destinations, taking fleeing Nazis and their plunder.’

‘A voyage like that could have extended well beyond the eighth of May,’ Jack said. ‘A U-boat could have set off from the Baltic just before the surrender and then taken a circuitous voyage across the Atlantic to avoid detection.’

‘Right,’ Mikhail replied. ‘Two Type IX U-boats, U-530 and U-977, refused Grand Admiral Donitz’s order and didn’t surrender until the tenth of July and the seventeenth of August respectively, both in Argentina. But as for U-boats in the Caribbean, that’s only ever been speculation. By yesterday afternoon I thought I’d reached a dead end. But then I remembered something from research I did in the US National Archives in Washington almost twenty years ago, soon after my defection. In Moscow I’d been a student of military history and then a defence analyst before being called up for service in Afghanistan. After my debriefing at Langley, I worked for several years as a researcher for the CIA historical division. They allowed me access to classified material in order to bring a Soviet intelligence perspective on periods of Cold War arms build-up that still remained poorly understood. As you know, Jack, my speciality has become the shift of Allied and Soviet strategic planning from the defeat of Nazi Germany to the Cold War stand-off, particularly during those crucial first months after the Nazi defeat. My interest really began when my CIA handlers asked me to file a report on the earliest Soviet plans for tactical nuclear bombing, for the use of atomic bombs as battlefield weapons. They let me look at classified files relating to comparable US plans, and that’s when I came across this account. I still have security clearance and was able to order a scan of the contents and have it couriered to me yesterday evening. The access records show that from the date when the file was boxed away in August 1945, nobody else has ever looked at it. I’d remembered it because it was so unusual, and also because it was the eyewitness report of an experienced combat aviator who would have known what he was looking at.’

‘Go on,’ Jack said, leaning forward.

Mikhail took an A4 black-and-white photograph from the file and slid it over the table. ‘You recognize that?’ Jack stared, then nodded. The picture showed a large-bellied four-engine aircraft in wartime British Royal Air Force camouflage, white underneath and on the fuselage sides, and khaki and olive green above, with a large RAF roundel on the centre of the fuselage and the red identification letters MA below the cockpit. In front of the letters was the image of a scantily clad woman and a roaring red dragon, and the words ‘Dragon Lady’.

‘It’s a B-24 Liberator,’ he said. ‘Somewhere in the tropics, judging by the palm trees beyond the tarmac. That’s the RAF Coastal Command camouflage scheme, isn’t it? Was this a submarine hunter?’

‘It’s a Liberator of 111 Operational Training Unit, based at Nassau in the Bahamas and used to train new aircrew on four-engine bombers. A lot of the aircrew were Canadians of the RCAF, as well as British and Commonwealth RAF men who had done their initial training in Canada. The Liberator had a longer range than the other main four-engine bombers used in the European war, and many of the crews were destined for the Far East to take part in operations against the Japanese.’

‘You mean about the time when the Americans were gearing up to drop the first atomic bomb.’

Mikhail nodded. ‘That’s what I was researching when I came across the records box with that picture. The box was peculiar because it contained papers and logbooks relating to 111 OTU in May and June 1945, material that would normally be found in England with the squadron operations records in the UK National Archives, or under restricted access along with other Second World War material still held by the Ministry of Defence. Its location in the US archives in Washington only made sense when I began reading the files and realized that they related to a secret training scheme co-ordinated by the US and were intimately tied up with the events of early August 1945, with the atomic bomb programme.’

Jack peered at the photograph. ‘My father was an RAF Lancaster pilot in the final months of the war. He told me I owed my existence to a silver butterfly that had kept him and his crew alive. It was a pendant left in the aircraft by the previous pilot, who’d brought his crew through two tours. My father kept the butterfly and had it in his hand when he died as an old man. That’s virtually all I know about his wartime experiences, as he never spoke of them. He said he was one of the lucky ones who was able to live for the future. I think that pendant had something to do with it. But he did talk a lot about his beloved Lancaster, so I grew up knowing a bit about planes. I was right, wasn’t I? This Liberator may have flown with a training unit, but she’s armed and equipped for operational flying.’

Mikhail nodded. ‘This is B-24D, serial number FK-856. You were right about Coastal Command. She’d been a Royal Canadian Air Force U-boat hunter based in Newfoundland, but with the Battle of the Atlantic winding down by early 1945, she was one of a number sent to operational training units. You can see she still has the chin fairing that houses the air-to-surface-vessel radar, and the airfoil winglets below the cockpit that carried eight five-inch rockets. Both of those features were removed when she went to 111 OTU, but the bomb-bay adaptation to carry depth charges was retained.’

‘What about the crew?’

‘That was what really piqued my interest. When I looked at the crew lists, I saw something odd. The usual operational conversion crews were men straight out of flight school. But the final crew to fly this Liberator was very different.’ Mikhail picked up the scanned sheets and flipped through them. ‘An inordinate amount of attention was paid to their selection, with secret reports from their squadron and station commanders as well as detailed intelligence assessments on each man. They were all highly experienced aircrew from the same elite RAF pathfinder group, the bombers that had flown ahead in the raids on Nazi Europe and marked the targets. Every member of the crew of FK-856 had flown at least a full tour of thirty missions over Europe, several of them a lot more; all four of the NCO gunners had Distinguished Flying Medals, the officers had Distinguished Flying Crosses and the pilot had the Distinguished Service Order as well. With the war in Europe over, many Lancaster crews were being remustered as part of “Tiger Force”, the plan to send RAF and Commonwealth squadrons to bomb Japan, and I could only think that this crew had been selected for special duties to get them to the Far East as soon as possible and were being converted to fly anti-submarine operations in the Pacific. But then I found the top-secret memo that explained it all. They were being given flight time on the Liberator before being sent to a secret destination in the Pacific to be upgraded to the Liberator’s successor, the B-32 “super-bomber”. They were being groomed to be the first generation of bomber crews to drop tactical nuclear weapons on the battlefield, something Allied commanders envisaged had the Hiroshima and Nagasaki bombs failed to persuade the Japanese to surrender.’

‘But then the war against Japan did end, and the programme was scrapped,’ Jeremy said.

Mikhael nodded, then pursed his lips. ‘Too late for these men, though. They may well count as the last combat casualties of the war against the Nazis.’

‘Explain,’ Jack said.

Mikhail picked out one sheet with a yellow marker stuck to it. ‘It was the morning of the third of June 1945. The crew had only been in Nassau for two weeks, having previously been involved in the airdrop of relief supplies to the emergency hospital units dealing with survivors of the Belsen concentration camp. One of their last bombing missions had been over Berlin, an attempt to use the “Tallboy” twelve-thousand-pound bomb to break the flak-tower defences. It was their expertise with those bombs that caught the eye of the US intelligence officers scouting for pathfinder crews suitable for conversion to nuclear bombing. The bomber crews were very tightly knit, and the pathfinders were the best of the best. The psychological reports show that these were not the kind of men who desperately counted down the last missions to the end of their tour, traumatized by what they had seen and done and by the constant fear. We often forget that some men relished it. The men in this crew seem to have been pleased to be selected to go out to the Far East ahead of Tiger Force, eager to get back into action again. These were precisely the kind of men the intelligence officers would have been looking for.’

‘So that day they were on a training mission?’ Jack asked.

Mikhail nodded, then took out a photocopied map with ruled lines on it. ‘It was their last operation in an intensive week. They were due to take their Liberator across the United States to the island of Guam in the Pacific the next day. They were fully armed as if they were on an anti-submarine patrol, with three depth charges in the bomb bay and the machine guns in the turrets fully belted up. The depth charges were an experimental type designed to bounce on the surface of the sea, hit their target and roll under it to explode, like the famous dambuster bombs. Their mission was to fly three hundred and fifty nautical miles east of Nassau to a designated live-fire zone just north of the central Bahamas chain, find a decommissioned minesweeper that had been anchored as a target and expend all their ammunition on it before returning in a clockwise route to Nassau. Their last radio contact shows that they made it to the live-fire zone, a rectangular area of about fifty square miles extending north from the island of San Salvador. Intermittently, there’s severe electromagnetic disturbance at this location, on the edge of the abyssal plain where the Bahamas shelf extends over the Atlantic plate, an extension of the Puerto Rico Fault Line that’s still poorly understood. It’s the kind of thing that would get Bermuda Triangle fantasists all excited, but an oceanographer colleague of mine at Columbia University thinks it might be a localized upsurge of the magma that affects the geomagnetic field, an anomaly that might also disrupt compasses.’

‘I’ve heard that before,’ Jack murmured, thinking hard. ‘About the North Anatolian Fault off Turkey, at the site of Atlantis. It makes some meteoritic materials seem heavier.’

‘That reference on the pillar at Lixus,’ Jeremy interjected. ‘“Where the palladion becomes heavier.”’

Jack nodded, leaning over and staring at the map. ‘I take it there was no more contact.’

‘None whatsoever. Over the next few days hurricane conditions prevented search-and-rescue flights, and by the time the weather had cleared, the Nassau station commander deemed that there was little chance the crew had survived. They found the anchored minesweeper completely untouched, so assumed the Liberator must have gone down before reaching it, on a flight path that was meant to take them on a compass bearing of thirty degrees from the northern tip of San Salvador out to sea towards a coral ridge where the minesweeper was anchored. The aircraft was meant to attack at very low level, and the base commander’s log concludes that she may have clipped the waves in the rising wind and gone into the sea intact, accounting for the absence of floating debris. That was pretty unusual for the Liberator, which tended to break up on ditching, but the pilot, Squadron Leader White, was exceptionally skilled. The case was closed, but was briefly reopened nearly three weeks later, when a horrifying discovery was made almost three hundred nautical miles south-east of their target off the far end of the Bahamas chain.’

He pulled out another photograph and passed it to Jack, who took it and stared. ‘Jesus,’ he said quietly. ‘I’ve seen harrowing pictures of survivors of wartime sinkings who’d endured weeks at sea in lifeboats, but this is one of the worst.’ He stared for a moment longer, and then passed it to Jeremy. It was a low-level aerial photo of a one-man inflatable boat Jack recognized from the survival equipment his father had once shown him in the RAF museum at Hendon. The pontoons were smudged and criss-crossed with markings. Inside was a man, apparently naked, beneath a scrappy awning that seemed to have been rigged using his battledress and life jacket. He was in a foetal position, but his face protruded under one side of the awning, blackened and horribly ulcerated.

‘Surely he can’t have been alive,’ Jeremy said.

‘He was, just,’ Mikhail replied. ‘He was so dehydrated that his eyeballs had shrunk into his head. After his emergency rations ran out, he’d survived by fishing, making his first catch using pieces of his own flesh as bait. He’d been trying to drink his own blood. That’s what those markings on the pontoons are, like finger painting, all kinds of numbers and slashes that must have been his way of marking the days. The Catalina aircraft that spotted him managed to land on the sea and pick him up, and he was taken back to Nassau. By then, 111 OTU unit had departed and everything was winding down. In the hospital he was debriefed by the last remaining US intelligence officer on the base, an inexperienced man who had been sent out to take the records of the secret programme back to Washington for classified storage. His report from that day is in the file. The rescued airman had no chance of recovery and died that night, but during brief periods of lucidity he told the story that caught my eye when I unearthed that box in the archives almost fifty years later.’

‘Go on,’ Jack said.

‘His name was Flight Sergeant Brown. He was the rear gunner of Liberator FK-856. You won’t find his name or those of any of the other crew on the Commonwealth War Graves Commission website, as officially they were lost in a peacetime training accident. He was English but had emigrated to Canada to make a new life on the prairies. His parents had been killed in the Blitz and he had no other recorded family. He was twenty-six when he died. From the debriefing, it’s clear that the pilot was talking to the crew right up to the plane’s final moments, fighting to keep it level as it dropped towards the sea. The Boulton Paul rear turret on the RAF Liberators was a deathtrap at high altitude if a plane went down, but it often came away on impact in a forced landing, and that’s probably what saved him. He said there was a fire, but the pilot managed to ditch the plane nose-up, dousing the rear turret with seawater before the flames reached him and causing the turret to break away. The Liberator’s poor ditching characteristics were mainly a result of the lightly built bomb-bay doors, which tended to collapse on impact, causing the fuselage to fill up quickly and sink. He said that when he recovered consciousness the aircraft had disappeared and the pilot and other crew were nowhere to be seen. At that location the plane could well have gone down beyond the abyssal wall, where the ocean is more than a mile deep, and by the time the surviving crew had struggled out of their harnesses it may have been too deep for any hope of escape.’

‘So a fire caused the crash?’ Jeremy asked.

‘He claimed they were shot down.’

‘ Shot down? ’ Jeremy said in disbelief. ‘Nearly a month after the war had ended? No way.’

‘That’s what the intelligence officer thought. Flight Sergeant Brown was delirious, in and out of consciousness, and I think the officer recorded what I’m about to tell you only as a matter of getting something into the debriefing report before closing the file. Brown kept repeating that they had depth-charged a U-boat over a blue hole, but had been shot down. The officer noted in pencil on the side that he’d checked Brown’s personnel record and seen that before joining the pathfinders he had done a tour with Coastal Command and had a similar experience, flying rear gunner in a Liberator in 1943 that depth-charged a U-boat off Newfoundland but was hit by machine-gun fire and forced to ditch. The officer evidently thought that the 1943 ditching was a traumatic experience that came out in Brown’s delirium. Even the blue-hole story was dismissed out of hand. Blue holes are a striking feature of the Bahamas from the air, and the officer noted that from his position of boredom cramped in the rear turret for hours on end, Brown may have become fixated on them.’

‘You mean the sinkholes where so many cave divers die?’ Jeremy said.

Jack nodded. ‘The Bahamas land mass is a limestone plateau, and during the last Ice Age the sea level was over a hundred metres lower than it is today. Rainwater percolated through the limestone and created huge cavern systems that became submerged as the sea rose after the end of the Ice Age. Where the roofs of the caverns have collapsed, they appear as deep blue holes in the reefs, or as depressions where the limestone fragments from the ceiling have collapsed and filled up the caverns.’

Jeremy turned to Mikhail. ‘But when you read the file, you believed Brown’s story?’

Mikhail paused. ‘I’ve been to war, and I know about post-traumatic flashbacks. The streets and hospitals of Russia are strewn with veterans of the Afghan war who’ve never been able to deal with it. The trauma, the flashback, is rarely generalized or conflated. It isn’t a mishmash of memories. It tends to be one specific event, remembered in exacting detail.’

‘You’re saying that Brown’s account wasn’t a product of delirium.’

‘I’m saying that if he was traumatized by his U-boat experience with Coastal Command in 1943, he wouldn’t have seen a blue hole in the flashback. He would have remembered everything from that event in 1943, but not added other memories. And anyway, the trauma idea doesn’t ring true. The intelligence officer was assuming what we might assume, that experiences such as that 1943 ditching must have been traumatic. But that’s just wrong. Flying night raids over Germany was about the most terrifying thing a man could do in that war, yet Brown and his fellow crew had done it over and over again, and volunteered for more. There was a reason they were selected for the nuclear programme. They were the toughest of the tough. Some people just don’t get traumatized.’

Jack peered at the map. ‘If he really was describing one specific blue hole, the trouble is there are hundreds of them in the Bahamas over several thousand square miles. All we have to go on is the last reported position of the aircraft over that sector north of the island of San Salvador.’

‘I looked into this with my oceanographer friend,’ Mikhail said. ‘At the co-ordinates of the target minesweeper noted in the file, the Liberator would have been beyond the land-mass plateau of the Bahamas and probably over the abyssal plain, beyond the huge underwater cliffs that run up from the Puerto Rico Fault along the Atlantic side of the Bahamas towards the coast of Florida. The plain is at least a mile deep and you won’t find blue holes there. But there’s one crucial feature we noticed. Off San Salvador there’s an undersea ridge that extends about twenty-five nautical miles north-east, rising up from the abyssal plain. The detailed bathymetry was unknown in 1945, but I wondered whether there might be sections of reef shallow enough to have been upstanding land mass in the Ice Age, enough for rainwater erosion to have formed caverns that might have become blue holes as the sea level rose. We just don’t know enough about the sea and reef at that point. That whole sector was a weapons test range, designated in April 1945 and in the event seeing little use. After the war it became part of the Atlantic Test and Evaluation range for anti-submarine weapons, continuing to be an exclusion zone even after the decision had been made to use another sector of undersea trench closer to Nassau for most testing. The San Salvador ridge extends beyond the twelve-nautical-mile Bahamas territorial limit, but the weapons test zone remains in force beyond the end of the ridge and we couldn’t find any record of exploration or diving there. So it’s possible that there is a shallow reef and a blue hole that has never been properly charted.’

Jack reached over and picked up the photograph showing the raft with the airman’s body slumped inside. He looked closely at the dark smears on the pontoons and the mass of marks the man had made with his own blood. He could just make out a sequence of numbers, possibly repeated several times, but the image needed to be magnified and sharpened for there to be any hope of reading it. He stared, his mind racing. Something was niggling him, something his father had told him when they had seen the survival equipment at the museum at Hendon, about how pilots were trained to think of what information the crew who escaped from a ditched aircraft might need to call in a rescue. He needed to get this image to Lanowski.

At that moment Mikhail’s two-way radio crackled and he spoke into it briefly, then got up. ‘Okay. That was Ben. There’s a propane tanker truck beginning to back down the lane. This was scheduled. Ben’s going to remain concealed, and will stay at the top of the lane until he’s relieved by John. I need to go out and make sure the path’s clear for the men to drag the hose to the propane tank. It’s hidden under a cedar growth beyond the barn.’

‘I’ll come with you,’ Jeremy said, getting up and stretching. ‘I need some fresh air. I’ll see if Rebecca’s out of the shower yet.’

‘Can I use the internet and a scanner?’ Jack asked.

Mikhail pointed to a monitor on a desk in an alcove. ‘Be my guest. It can be a little slow out here. There’s Skype if you need it.’

Mikhail and Jeremy left the room together, and Jack went over to the desk and sat down. He opened up the IMU home page and quickly logged on, then accessed his email account and clicked on the Skype. He checked his watch. Seaquest II was in a different time zone, one hour ahead of Bermuda, and he guessed that by now Lanowski and Costas would have their heads down over the computers in the operations room. He picked up the landline phone and dialled IMU Headquarters in Cornwall. The phone was answered immediately. ‘Hello, this is Jack Howard. Please patch me through to Seaquest II. Get me a secure line. This is a priority call.’
