The Last Detective

PART THREE
The Men in White Coats
Chapter One

THE INCIDENT ROOM IN MANVERS Street Police Station was not as crowded as the caravan had been. Paperclips no longer danced in their boxes each time Peter Diamond walked across the floor. Nor could the filing clerks feel his breath on the backs of their necks. Loose papers and file cards were not so likely to be brushed off the edges of desks. The carousel of cards, instead of dominating the room, had been relegated to a corner. Four Trojan horses – as Diamond dubbed them – in the form of computer terminals, stood on a table near the door. The Police Committee had decreed that no major inquiry should be without its computer back-up, irrespective of the prejudices of one cantankerous detective.

'We'll soon have them up and running, sir,' Inspector Dalton, who came with the computers and four civilian operators, had rashly promised.

To this, Diamond had responded, 'Up where? Up yours, as far as I'm concerned.'

Apart from that, the air of desperation beside the lake had been supplanted by confidence. They were working to a purpose now. In the hackneyed, but comforting phrase, a man was assisting the police with their inquiries. He had been in the interview room for an hour and a half.

Diamond and John Wigfull came out for a sandwich. Neither was wearing a jacket. The Last Detective was in his element. He had loosened his tie and unfastened the top button of his shirt. His confidence was high and he wanted everyone to know. He didn't so much as glance at the computer screens. He expected all fresh developments in the case to come from the interviewing of Professor Jackman. With his weight securely deposited on a desk, he snapped open a can of beer and remarked to Wigfull, 'You know what this amounts to – this story about the fire?'

Wigfull waited. He was no reader of minds.

'He's laying the foundations for his defence,' Diamond said. 'Mentally he's already in court, pleading mitigation. She tried to kill him on this previous occasion, so when it happened a second time he defended himself. Didn't know his own strength. Panicked. Tried to get rid of the body by dumping it in the lake. See if I'm not right, John.'

Wigfull's eyebrows were raised. 'That isn't the way he told it yesterday.'

Diamond was unmoved. 'They always start by giving you the clean-as-driven-snow gambit. Left her sleeping peacefully and never saw her again. He's had plenty of time to concoct his story. That's only his first line of defence. He doesn't really expect to hold it long and he won't.'

'You think he's ready to admit he killed her?'

'Not yet. Jackman's got a good head on his shoulders, remember. First, he wants to win us over and show himself in the best possible light. But this stuff about the summerhouse, this shows how his mind is working.'

'You don't believe it, sir?'

Diamond said nothing, letting his silence make the point.

'The summerhouse was burned down,' Wigfull pointed out.

'Agreed. Did he report it at the time? No. He can give it any slant he wants.'

'Should we ask forensic to take a look at the site, see if the evidence bears out his story?'

'It's already in hand.' Diamond couldn't help sounding smug. He enjoyed keeping mentally ahead of Wigfull, who was no idiot. With the air of an achiever, he tugged at the packet containing the egg and cress sandwich he had ordered. 'Mind you, the lab will take weeks to come up with anything helpful. You and I can crack this today.' Unable to find a way into the packet, he squeezed it. The result was a pulverized sandwich. Furious, he flung the whole thing at the nearest waste-bin and missed.

'Want one of mine, sir – lettuce and tomato?' offered Wigfull.

'Rabbit food. Let's have another go at him. I need an early supper tonight.'

'Are you going to caution him?'

A guarded look closed over Diamond's blunt features. 'Is that advice, or what?'

Wigfull reddened. 'I thought if we have reasonable grounds, we ought to issue the caution.'

Diamond jabbed a finger against his assistant's shirtfront. 'Don't ever tell me my job, Inspector. What I told you just now – about his guilt – was a gut feeling. If you and I are going to work as a team you'd better get one thing straight: if I speak my thoughts aloud, that's my privilege. If I want yours, I'll bloody ask for them. Understood?'

'Understood, sir.'

'I cautioned him last night, before he said a bloody word to me. Remind him when we go in.'

Professor Jackman glanced down at his watch as they returned. He seemed so well in control that he might have been about to put the questions to them. On the desk in front of him was an empty mug and one biscuit, the last of a packet of three. Diamond reached for it and scooped it into his mouth in one rapid movement.

The constable taking shorthand slipped in unobtrusively behind them and took her place to the rear of Jackman, just as Wigfull was reinforcing the caution.

Diamond didn't waste time over small-talk. 'Getting back to the fire in the summerhouse, Professor, I take it that you got out without serious injury.'

Jackman's response was even more to the point. 'Yes.'

'You managed to rouse yourself when you sensed the danger?'

'Not without difficulty. It took an exceptional effort.'

'You're certain that you were drugged?'

'Not without difficulty. It took an exceptional

'You're certain that you were drugged?'

'I'm convinced of it. She must have used the phenobarbitone she had from the doctor. God knows how many tablets she'd crushed and mixed in the sauce she gave me. If I hadn't made myself sick, as I told you, I wouldn't have recovered consciousness at all.'

'You were lucky.'

'You can say that again. In a matter of seconds I would have been incinerated. My shoes and trousers were smouldering when I got out.'

'I suppose it's too much to hope that you kept them?'

'The shoes and trousers? I threw them away. They were no use any more.' His eyes narrowed. 'You do believe what I'm telling you?'

Diamond answered equivocally, 'I saw the burnt-out summerhouse.' He leaned back in his chair and clasped his hands behind his neck. 'What interests me, Professor, is what happened next. Your wife had tried to kill you. What did you do about it?'

'I was in no state to do anything. I flopped down on the lawn at a safe distance from the flames and watched the fire burn itself out. I still had some of the drug in my system and I must have fallen asleep, because the next thing I knew it was daylight and I was aching in every bone. Everything seemed like a dream except that I had in front of me the heap of ashes that had been the summerhouse. I went into the house to look for my wife. She'd behaved like a madwoman but she was no fool. She'd quit the place.'

'How did you know?'

'Her car wasn't in the garage.'

'So what did you do?'

'Slept a few hours more. I was still too muzzy to go looking for her. And when I came to, I started slowly clearing up after the party. I needed to occupy myself in a practical way.'

Rebuking him mildly, as if remarking on a social gaffe, Diamond said, 'You didn't notify us.'

'You?'

'The police.'

'I wanted Gerry's explanation.'

'But you didn't know where she was. She could have killed herself. People frequently do after murdering a spouse.'

Jackman said dryly, 'People clever enough to dress up a murder as an accident don't spoil it by committing suicide. I knew she would come back.'

Diamond exchanged a glance with John Wigfull. 'You're telling us you just started clearing the dishes?'

Jackman rested his elbows on the table and leaned forward to make a point. 'Look, I'm here of my own free will. I'm telling you what happened. I don't expect to have my behaviour called into question.'

With the air of a man whose behaviour had been questioned too many times to matter any more, Diamond commented, 'We're simply trying to understand why things turned out as they did. Let's move on, shall we? When did you see your wife again?'

'The same day, early that evening.'

'She came back to the house?'

'Yes.' Jackman related the events with a directness that was vivid and convincing. 'She didn't come into the house immediately. I watched her leave the car on the drive and walk around the side to the garden. She was wearing the black tracksuit that I remembered seeing her in. She stood for a moment staring at the gutted summerhouse. She didn't go too close to it, just stood about thirty yards away, fingering her hair. Then she turned and approached the house. She came in by the patio windows, which were still open.' He smiled slightly. 'Of course, she was shocked out of her skin when she saw me sitting in front of the TV with my feet up. She damned near passed out. I had to pour her a drink. I didn't accuse her right out. I wanted to see what she would make of it, so I asked where she'd been all day. She said she'd gone out early and spent the day on a deckchair in Parade Gardens catching up on her sleep. She said she couldn't face being in the house. Quite possibly she was telling the truth.'

'And what happened when you did broach the litde matter of the fire?'

'She denied it, naturally. Said I must have dreamed the bit about her coming into the summerhouse. She insisted that I must have dropped a lighted cigar and set light to the place myself – which you can bet is the story she would have put about if she'd succeeded in killing me. There's no chance that it was true,'Jackman said quickly, as if sensing that he'd given them an opening. 'In the first place, she definitely drugged me.'

'Let's say that someone drugged you,' said Diamond.

Jackman was quick to scotch that amendment. 'Listen, Geraldine had the drug in her possession. She had the sauce put aside for me. She insisted on collecting it herself. She poured it all over the food. Within a short time of eating it, I was three parts slewed. She'd put the cigars and the spirits ready beside the camp-bed in the summerhouse. It was all set up. And I'm certain it wasn't a dream when I saw her there because I noticed what she was wearing. She was still wearing that black tracksuit when she came back the next day.'

'You mentioned that already. You've been over this many times in your mind, haven't you?'

Jackman nodded. 'And the conclusion is irresistible.'

'All right, Professor,' said Diamond cheerfully, as if he accepted every word of the story. 'Why do you think it happened?'

'Why did she try to kill me?'

'Yes.'

Jackman lodged his face ruminatively against his hand. 'I put it down to her mental state. As I explained, some time before that evening she was showing symptoms of paranoia. She imagined I was plotting her downfall, or something. It was illusory, a fantasy, but plainly very real to her. I didn't appreciate how serious her mental state had become – until that night.'

'Did she have any history of disturbance?'

'Only what I've described. I'm no psychiatrist.'

'Paranoia,' Diamond repeated, and with a gleam of mischief looked across at the constable taking notes. 'Do you want the professor to spell that?'

The PC shook her head.

Diamond swung back to Jackman. 'And how about you? Did you feel persecuted?'

Jackman tensed and drew back from the desk. 'What?'

'Persecuted or threatened, at least. I should think you were entitled to feel like that after what happened.'

'I wouldn't describe it in those terms.'

'Would you care to describe it in your own terms then?'

The professor hesitated, and when he spoke it was with reluctance, as if he were being drawn into alien territory. 'Naturally there was a loss of trust on my part. I had to be on my guard in future.'

'You thought you could look after yourself?'

'She wasn't going to rush at me with an axe, or something. At least, that's the way I saw it. A lot of planning had gone into the summerhouse incident, mainly to ensure that the killing would be passed off as an accident. She didn't want to be caught. If she plotted another attempt on my life, I thought I was capable of picking up the signals before it got really dangerous.'

'Brave man,' commented Diamond, without actually meaning it.

Jackman leaned forward to solicit more understanding. 'When you've lived with a person, married them, shared their joys and disappointments, you've got to believe you have some influence, some hope of making sense to them. Okay, the magic had gone from our marriage, but we didn't have to destroy each other.'

There was a silence. Neither Diamond nor Wigfull would say one word to deflect him from what sounded like the beginning of a confession.

Jackman appeared to see the expectation in their eyes, because he said, 'I'll put that another way. I was willing to take my share of responsibility for what had happened. We'd made mistakes in our marriage. I'd alienated Gerry by failing to reach out to her mentally. The best thing I could do was try and remove the suspicions she harboured.'

'Give her the benefit of the doubt?'

'There was no doubt,' said Jackman flatly. 'She tried to kill me and failed. The fact that I knew for certain was my safeguard.'

Someone tapped on the door and opened it. Diamond wheeled around in his chair, ready to raise hell. He couldn't abide interruptions when he was interviewing a witness. But the intruder was the police doctor, accompanied by a constable carrying a kidney-shaped steel bowl containing a syringe and other items. 'Ah,' said Diamond, reconciled. He turned back to address Jackman, whose face was a study in disbelief and alarm, 'I asked the doctor to step in. We'd like to take a sample of your blood for the forensic lab. It's a routine procedure. I take it we can rely on your co-operation?'

'Just a blood sample?'

Diamond grinned unkindly. 'What did you expect – a truth drug?'
