‘Eighteen months ago, I was introduced to a quite extraordinary man by the name of Cornelius Stillman who was in London at the end of a lengthy European tour. His home was on the East Coast of America and he was what is termed a Boston Brahmin, which is to say that he belonged to one of their most elevated and honoured families. He had made a fortune from the Calumet and Hecla mines and had also invested in the railroads and the telephone companies. In his youth, he had apparently had ambitions to become an artist and part of the reason for his visit was to visit the museums and galleries of Paris, Florence, Rome and London.
‘Like many wealthy Americans, he was imbued with a sense of civic responsibility that did him great credit. He had purchased land in the Back Bay area of Boston and had already begun work on the construction of an art gallery which he called The Parthenon and which he planned to fill with the finest works of art, purchased on his travels. I met him at a dinner party and found him to be a huge volcano of a man, brimming with energy and enthusiasm. He was rather old-fashioned in his dress, bearded and affecting a monocle, but he proved to be remarkably well informed, fluent in French and Italian with a smattering of ancient Greek. His knowledge of art, his aesthetic sensibility, also set him apart from many of his fellow citizens. Do not think of me as unnecessarily chauvinistic, Mr Holmes. He himself told me of the many shortcomings of the cultural life to which he had become accustomed as he grew up — how great paintings had been exhibited next to freaks of nature such as mermaids and dwarves. He had seen Shakespeare performed with interludes by tightrope walkers and contortionists. Such was the way of things in Boston at the time. The Parthenon would be different, he said. It would, as its name implied, be a temple to art and to civilisation.
‘I was overjoyed when Mr Stillman agreed to come to my gallery in Albemarle Street. Mr Finch and I spent many hours in his company, taking him through our catalogue and showing him some of the purchases we had recently made in auctions around the country. The long and the short of it was that he bought from us works by Romney, Stubbs and Lawrence but also a series of four landscapes by John Constable which were quite the pride of our collection. These were views of the Lake District, painted in 1806, and unlike anything else in the artist’s canon. They had a profundity of mood and spirit that was remarkable, and Mr Stillman promised that they would be exhibited in a large and well-lit room that he would design specifically for them. We parted on excellent terms. And in view of what happened, I should add that I banked a substantial sum of money. Indeed, Mr Finch remarked that this was undoubtedly the most successful transaction of our lives.
‘It now only remained to send the works to Boston. They were carefully wrapped, placed in a crate and dispatched with the White Star Line from Liverpool to New York. By one of those twists of fate that mean nothing at the time but which will later return to haunt you, we had intended to send them directly to Boston. The RMS Adventurer made that journey but we missed it by a matter of hours and so chose another vessel. Our agent, a bright young man by the name of James Devoy, met the package in New York and travelled with it on the Boston and Albany Railroad — a journey of one hundred and ninety miles.
‘But the paintings never arrived.
‘There were, in Boston at this time, a number of gangs, operating particularly in the south of the city, in Charlestown and Somersville. Many of them had fanciful names such as the Dead Rabbits and the Forty Thieves and had come originally from Ireland. It is sad to think that, having been welcomed into that great country, their return to it should have been lawlessness and violence, but such was the case and the police had been unable to restrain them or bring them to justice. One of the most active and most dangerous groups was known as the Flat Cap Gang, headed by a pair of Irish twins — Rourke and Keelan O’Donaghue, originally from Belfast. I will describe these two devils to you as best as I can, because they are central to my narrative.
‘The two of them were never seen apart. Although they were identical when they were born, Rourke was the larger of the two, square-shouldered and barrel-chested with heavy fists that he was always ready to use in a fight. It is said that he beat a man to death in a game of cards when he was barely sixteen. By contrast, his twin stood very much in his shadow, smaller and quieter. Indeed, he seldom spoke at all — there were rumours that he was unable to. Rourke was bearded, Keelan clean-shaven. Both wore flat caps and it was this that gave the gang its name. It was also widely believed that they carried each other’s initials, tattooed on their arms, and that in every aspect of their lives they were inseparable.
‘Of the other gang members, their names tell you perhaps as much as you would wish to know about them. There was Frank “Mad Dog” Kelly and Patrick “Razors” Maclean. Another was known as “The Ghost” and was feared as much as any supernatural being. They were involved in every conceivable form of street crime, robberies, burglaries and protectionism. And yet, at the same time, they were held in high regard by many of the poorer inhabitants of Boston who seemed unable to recognise them as the foul pestilence that they undoubtedly were to the community. They were the underdogs, waging war on an uncaring system. I need hardly point out to you that twins have appeared in mythology since the very dawn of civilisation. There are Romulus and Remus, Apollo and Artemis and Castor and Pollux, for ever immortalised as Gemini in the night sky. Something of this attached itself to the O’Donaghues. There was a belief that they would never be caught, that they could get away with anything.
‘I knew nothing about the Flat Cap Gang — I had never even heard of them — when I sent off the paintings at Liverpool but somehow, at exactly the same time, they were tipped off that a large amount of currency was about to be transferred from the American Bank Note Company in New York to the Massachusetts First National Bank in Boston a few days hence. The sum in question was said to be one hundred thousand dollars and it was travelling on the Boston and Albany Railroad. Some say that Rourke was the brains behind their operation. Others believe that Keelan was the more natural mastermind of the two. In any event, between them they arrived at the idea of holding up the train before it could reach the city and making off with the cash.
‘Train robberies were still prevalent in the western frontiers of America, in California and Arizona, but for such a thing to take place on the more developed eastern seaboard was almost inconceivable and that is why the train left the Grand Central Terminal in New York with only one armed guard stationed in the mail car. The banknotes were contained in a safe. And by some wretched chance, the paintings were still in their crate, travelling in the same compartment. Our agent, James Devoy, was travelling in second class. He was always assiduous in his duties and had taken a seat as close to the mail car as possible.
‘The Flat Cap Gang had chosen an area just outside Pittsfield for the attempted raid. Here, the track climbed steeply upwards before crossing the Connecticut River. There was a tunnel that ran for two thousand feet and, according to railway regulations, the engineer was obliged to test his brakes at the exit. The train was therefore travelling very slowly as it emerged and it was a simple matter for Rourke and Keelan O’Donaghue to jump down onto the roof of one of the wagons. From here, they climbed over the tender and, to the astonishment of the driver and his brakeman, they suddenly appeared in the engine cab with guns drawn.
‘They ordered the train to come to a halt in a forest clearing. They were surrounded by white pine trees that soared up all around, forming a natural screen behind which they might commit their crime. Kelly, Maclean and all the other members of the gang were waiting with horses — and with dynamite which they had stolen from a construction site. All of them were armed. The train drew in and Rourke struck the driver with the side of his revolver, concussing him. Keelan, who had not uttered a word, produced some rope and tied the brakeman to a metal stanchion. Meanwhile, the rest of the gang had boarded the train. Ordering the passengers to remain seated, they approached the mail car and began to set charges around the door.
‘James Devoy had seen what was happening and was in despair of the consequences. He must have guessed that the robbers were here for reasons other than the Constables. After all, very few people knew of their existence, and even if they’d had the wit or the education to recognise the work of an old master, there would have been no one to whom the paintings could be sold. While the other passengers cowered all around him, Devoy left his seat and climbed down, meaning to plead with the gang. At least, I assume that was his intention. Before he could say a word, Rourke O’Donaghue turned on him and gunned him down. Devoy was shot three times in the chest and died in a pool of his own blood.
‘Inside the mail car, the security guard had heard the shots and I can only imagine the terror he must have felt as he heard the gang members operating outside. Would he have unlocked the door if they had demanded it? We will never know. A moment later, a huge explosion rent the air and the entire wall of the carriage was blown apart. The guard was killed instantly. The safe with the money was exposed.
‘A second, smaller charge sufficed to open it and now the band discovered that they had been misinformed. Only two thousand dollars had been sent to the Massachusetts First National Bank, a fortune perhaps to these vagabonds, but immeasurably less than they had hoped for and expected. Even so, they snatched up the notes with whoops and cries of exaltation, not caring that they had left two men dead behind them and unaware that their explosives had utterly destroyed four canvases which alone were worth twenty times what they had taken. These, and the other works, were and are an incalculable loss to British culture. Even now I have to remind myself that a young and dutiful man died that day, but I would be lying to you if I did not say that, shameful to admit, I mourn the loss of those paintings just as much.
‘My friend, Finch, and I heard the news with horror. At first we were led to believe that the paintings had been stolen and would have preferred it had this been the case, for at least the works would still have been appreciated by someone and there was always a chance that they might be recovered. But such an unhappy accident of timing, wanton vandalism in pursuit of a handful of cash! How bitterly we regretted the route we had chosen and blamed ourselves for what had occurred. There were also financial considerations. Mr Stillman had paid a large deposit for the paintings but, according to the contract, we were entirely responsible for them until they were delivered into his hands. It was fortunate that we were insured with Lloyd’s of London or else we would have been wiped out, as eventually I would have no choice but to repay the money. There was also the matter of James Devoy’s family. I now learned that he had a wife and a young child. Someone would have to take care of them.
‘It was for these reasons that I resolved to travel to America and I left England almost at once, arriving first in New York. I met Mrs Devoy and promised her that she would receive some compensation. Her son was nine years old and a sweeter, more good-looking child would be hard to imagine. I then travelled to Boston and from there to Providence, where Cornelius Stillman had built his summer house. I have to say that even the many hours I had spent in the company of the man had failed to prepare me for the spectacle that met my eyes. Shepherd’s Point was huge, constructed in the style of a French chateau by the celebrated architect Richard Morris Hunt. The gardens alone stretched out for thirty acres and the interior displayed an opulence beyond anything I could have imagined. Stillman himself insisted on showing me round, and it is a journey I will never forget. The magnificent wooden staircase that dominated the Great Hall, the library with its five thousand volumes, the chess set that had once belonged to Frederick the Great, the chapel with its ancient organ once played by Purcell … by the time we reached the basement with its swimming pool and bowling alley, I was quite exhausted. And as for the art! Well, I counted works by Titian, Rembrandt and Velasquez, and this before I had even reached the drawing room. And it was while I was considering all this wealth, the limitless funds on which my host must be able to draw, that an idea formed in my mind.
‘Over dinner that night — we were sitting at a vast, medieval banqueting table and the food was carried in by negro servants dressed in what you might call colonial style — I raised the subject of Mrs Devoy and her child. Stillman assured me that even though they were not resident in Boston, he would alert the city fathers who would take care of them. Encouraged by this, I went on to the matter of the Flat Cap Gang and asked if there was any way he could help bring them to justice, the Boston police having so far signally failed to make any progress. Might it not be possible, I suggested, to offer a sizeable reward for information as to their whereabouts and, at the same time, to hire a private detective agency to apprehend them on our behalf. In this way we would avenge the death of James Devoy and simultaneously punish them for the loss of the Constable landscapes.
‘Stillman seized on my idea with enthusiasm. “You’re right, Carstairs!” he cried, bringing his fist crashing down. “That’s exactly what we’ll do. I’ll show these bums that it was a bad day that they chose to hornswoggle Cornelius T. Stillman!” This was not his usual manner of speech, but we had had between us finished a bottle of particularly fine claret and had moved on to the port and he was in a more than usually relaxed mood. He even insisted on funding the full cost of the detectives and the reward himself, although I had offered to make a contribution. We shook hands on it and he suggested that I stay with him while the arrangements were made, an invitation I was glad to accept. Art has been my life, both as a collector and as a dealer, and there was enough in Stillman’s summer home to keep me entranced for months.
‘But in fact, events took a swifter course than that. Mr Stillman contacted Pinkerton’s and engaged a man called Bill McParland. I was not invited to meet him myself — Stillman was the sort of person who must do everything alone and in his own way. But I knew enough of McParland’s reputation to be sure that he was a formidable investigator who would not give up until the Flat Cap Gang had been delivered into his hands. At the same time, advertisements were placed in the Boston Daily Advertiser offering a reward of $100 dollars — a considerable sum — for information leading to the arrests of Rourke and Keelan O’Donaghue and all those associated with them. I was glad to see that Mr Stillman had included my name along with his own beneath the announcement, even though the money was entirely his.
‘I spent the next few weeks at Shepherd’s Point and in Boston itself, a remarkably handsome and fast-growing city. I travelled back to New York a few times and took the opportunity to spend several hours at the Metropolitan Museum of Art, a poorly designed building, though containing a superb collection. I also visited Mrs Devoy and her son. It was while I was in New York that I received a telegram from Stillman, urging me to return. The size of the reward had achieved its aim. McParland had been given a tip-off. The net was closing in on the Flat Cap Gang.
‘I returned at once, taking a room at a hotel on School Street. And it was there, in the evening, that I heard from Cornelius Stillman what had occurred.
‘The tip-off had come from the owner of a dramshop — which is what the Americans call a saloon — in the South End, a less than salubrious part of Boston and one that was already home to a large number of Irish immigrants. The O’Donaghue twins were holed-up in a narrow tenement house close to the Charles River, a dark, squalid building on three storeys with dozens of rooms clustered together, no hallways and just one privy serving each floor. Raw sewage ran through the corridors and the stench was only kept at bay by the fumes of charcoal, burning in a hundred tiny stoves. This hell-hole was filled with screaming babies, drunken men and mumbling, half-crazed women, but a rough construction, mainly of timber with a few pressed bricks, had been added separately at the back and this the twins had managed to make their own. Keelan had one room to himself. Rourke shared another with two of his men. A third room was occupied by the rest of the gang.
‘The money they had stolen from the train was already gone, frittered away on alcohol and gambling. As the sun set that evening, they were crouched around the stove, drinking gin and playing cards. They had no look-out. None of the families would have dared to peach on them and they were sure that the Boston police had long ago lost any interest in the theft of two thousand dollars. And so they were oblivious to the approach of McParland who was closing in on the tenement, accompanied by a dozen armed men.
‘The Pinkerton’s agents had been instructed to take them alive if they could for it was very much Stillman’s hope that he would see them in a court of law, besides which there were many innocent people in close proximity making an all-out gunfight something to be avoided if at all possible. When his men were in position, McParland took up the bullhorn he had brought with him and called out a warning. But if he had hoped that the Flat Cap Gang would surrender quietly, he was disillusioned a moment later by a volley of shots. The twins had allowed themselves to be taken by surprise, but they were not going to give up without a fight, and a cascade of lead poured out into the street, fired not just out of windows but through holes punched in the very walls. Two of the Pinkerton men were gunned down and McParland himself was wounded, but the others gave as good as they got, emptying their six-shooters directly into the structure. It is impossible to imagine what it must have been like as hundreds of bullets tore through the flimsy wood. There was no protection. There was nowhere to hide.
‘When it was all over, they found five men lying together in the smoke-filled interior, their bodies shot to pieces. One had escaped. At first it seemed impossible, but McParland’s informant had assured him that the entire gang would be assembled in that place and during the gunfight it had seemed to him that six men had returned their fire. The room was examined and at last the mystery was solved. One of the floorboards was loose. It was pulled aside to reveal a narrow gulley, a drainage ditch which sank below the surface of the ground and continued all the way to the river. Keelan O’Donaghue had escaped by this means, although it must have been the devil of a tight squeeze for the pipe was barely large enough to contain a child, and certainly none of the Pinkerton’s agents was willing to give it a try. McParland led some of his men down to the river but by now it was pitch-dark and he knew any search would be fruitless. The Flat Cap Gang was destroyed but one of its ringleaders had got away.
‘This was the outcome that Cornelius Stillman described to me in my hotel that night, but it is not by any means the end of the story.
‘I remained in Boston another week, partly in the hope that Keelan O’Donaghue might even now be found. For a slight concern had risen in my mind. Indeed, it might have been there from the very start, but it was only now that I became conscious of it. It referred to that blasted advertisement which I have already mentioned and which bore my name. Stillman had made public the fact that I had been party to the reward and to the posse which had been sent after the Flat Cap Gang. At the time I had been gratified, thinking only of my sense of public duty and, I suppose, the honour of being associated with the great man. It now occurred to me that to have killed one twin and to have left the other alive might make me a target for revenge, particularly in a place where the very worst criminals could count on the support of so many friends and admirers. It was with a sense of nervousness that I now walked in and out of my hotel. I did not stray into the rougher parts of the city. And I certainly didn’t go out at night.
‘Keelan O’Donaghue was not captured and there was even some doubt that he had actually survived. He could have been wounded and died of blood loss, like a rat, underground. He could have drowned. Stillman had certainly persuaded himself that this was the case by the time we met for the last time, but then, he was the sort of man who never liked to admit failure. I had booked passage back to England on the SS Catalonia, run by the Cunard line. I was sorry not to be able to bid farewell to Mrs Devoy and her son, but I did not have the time to return to New York. I left the hotel. And I remember that I had actually reached the gangplank and was about to board the ship when I heard the news. It was being shouted out by a newsboy and there it was, on the front page.
‘Cornelius Stillman had been shot dead whilst walking in the rose garden of his home in Providence. With a shaking hand, I purchased a copy of the newspaper and read that the attack had happened the day before; that a young man wearing a twill jacket, scarf and flat cap had been seen fleeing from the scene. A manhunt had already begun and would spread all over New England, for this was the murder of a Boston Brahmin and no effort could be spared in bringing the perpetrator to justice. According to the report, Bill McParland was assisting the police and there was a certain irony in this, as he and Stillman had fallen out in the days before Stillman’s death. Stillman had held back half the fee that he had agreed with the Pinkerton man, arguing that the job would not have been fully completed until the last body had been recovered. Well, that last body was up and walking, for there could be no doubt at all as to the identity of Stillman’s assailant.
‘I read the newspaper and then climbed the gangplank. I went directly to my cabin and remained there until six o’clock in the evening when there was a tremendous hoot and the Catalonia lifted its moorings and slipped out of port. Only then did I return to the deck and watch as Boston disappeared behind me. I was hugely relieved to be away.
‘That, gentlemen, is the story of the lost Constables and my visit to America. I of course told my partner, Mr Finch, what had occurred, and I have spoken of it with my wife. But I have never repeated it to anyone else. It happened more than a year ago. And until the man in the flat cap appeared outside my house in Wimbledon, I thought — I prayed — that I would never have to refer to it again.’
Holmes had finished his pipe long before the art dealer came to the end of his narration, and had been listening with his long fingers clasped in front of him and a look of intense concentration on his face. There was a lengthy silence. A coal tumbled and the fire sparked. The sound of it seemed to draw him out of his reverie.
‘What was the opera you intended to see tonight?’ he asked.
It was the last question I had expected. It seemed to be of such trivial importance in the light of everything we had just heard that I wondered if he was being deliberately rude.
Edmund Carstairs must have thought the same. He started back, turned to me, then back to Holmes. ‘I am going to a performance of Wagner — but has nothing I have said made any impression on you?’ he demanded.
‘On the contrary, I found it of exceedingly great interest and must compliment you on the clarity and attention to detail with which you told it.’
‘And the man in the flat cap …’
‘You evidently believe him to be this Keelan O’Donaghue. You think he has followed you to England in order to exact his revenge?’
‘What other possible explanation could there be?’
‘Offhand, I could perhaps suggest half a dozen. It has always struck me that any interpretation of a series of events is possible until all the evidence says otherwise and even then one should be wary before jumping to a conclusion. In this case, yes, it might be that this young man has crossed the Atlantic and found his way to your Wimbledon home. However, one might ask why it has taken him more than a year to make the journey and what purpose he had in inviting you to a meeting at the church of St Mary. Why not just shoot you down where you stood, if that was his intent? Even more strange is the fact that he failed to turn up.’
‘He is trying to terrorise me.’
‘And succeeding.’
‘Indeed.’ Carstairs bowed his head. ‘Are you saying that you cannot help me, Mr Holmes?’
‘At this juncture, I do not see that there is a great deal I can do. Whoever he may be, your unwanted visitor has given us no clue as to how we may find him. If, on the other hand, he should reappear, then I will be pleased to give you what assistance I can. But there is one last thing I can tell you, Mr Carstairs. You can enjoy your opera in a tranquil state of mind. I do not believe he intends to do you harm.’
But Holmes was wrong. At least, that was how it appeared the very next day. For it was then that the man in the flat cap struck again.
