These were the questions that had prevented me getting anywhere near the seven hours' slumber I need to function at what passes for optimum efficiency. I'd even managed to incorporate Carla Graham into the various theories and trains of thought I'd tossed about my brain. In the better ones, I'd solve the case, find the killer (even going so far as catching him as he prepared to despatch his latest victim), get a promotion, and end up fucking Carla's brains out.

Fat chance. But at least a man can dream.

The bacon sandwich tasted good anyway, and I was so hungry I even ate the apple down to the core.

At 9.15, Knox came into the incident room with a very tired-looking Welland. Welland sat down immediately and it looked like he needed to. Knox, meanwhile, addressed the rest of us. 'We've just told Mark Wells about the latest developments and once again he categorically denies any involvement, but, to use the old phrase, he would say that, wouldn't he? He certainly looks far more worried than he has been. As we all know, he's a cocky bastard, and he's lost a lot of that now. We should get the rest of the results on the shirt later this morning and they'll tell us whether it belongs to Wells or not, although from the way he's behaving, I feel fairly certain it's his.'

'So we're going to be knocking out the champers later, then?' This was Capper.

Knox smiled. 'It's far too early even to think about a celebration drink yet. We've done well, very well, and it's been a team effort, but until you hear otherwise, it's still business as usual.'

He strode into his office, leaving Welland where he'd sat down. One of the women DCs asked Welland if he was all right. 'Yeah, yeah, I'm fine,' he replied. 'Just a bit under the weather.' Someone suggested that he go home for the day, but he said he'd stick around and wait for Wells to be charged. 'I want to see that bastard squirm,' he said, with more vigour than I'd have thought his body would allow.

'He looks terrible,' said Malik quietly, turning to me.

'Yeah, I know. He should take a few days off. He needs it. And the taxpayer owes him a break. He's done a good job on behalf of society.'

Not that anyone had ever thanked him for it; or any of us, for that matter. It may be that it's not accurate to describe all coppers as unsung heroes, but neither is it fair to view them as the constant villains of the piece, which is usually the way we're portrayed whenever we get a mention on the box. And Welland, more than most, was one of the good guys. He'd put his all into policework, so now he might as well take something back.

'If I was him, I'd go for early retirement,' said Malik.

'If I was him, I'd have gone for it ten years ago.'

He gave me a disbelieving smile. 'No you wouldn't. You enjoy the whole thing too much.'

'Bullshit I do.'

My phone rang and I had a sudden rush of adrenalin, hoping it was Carla. But if she was the person I most wanted to speak to, then the person on the other end of the line had to be one of those whose voice I least wanted to hear.

'It's a Jean Ashcroft for you, Mr Milne,' said the civilian receptionist.

Christ, what the hell did she want? 'Thanks, can you put her through?' There was a pause as she came on the line. 'Hello, Jean. Long time no speak.'

'Hello, Dennis. Look, I'm sorry to bother you…' Her tone was strained, formal.

'It's no problem. No problem at all. What can I do?'

'It's Danny,' she said. 'I think he might be in trouble.'

'What makes you say that?'

'Well, he phoned me last night and, you know, he never normally phones me, so I knew something wasn't right. He didn't sound himself, Dennis. It was all very strange. I think he'd been drinking, or smoking something, and he was rambling, going on about changing his life, doing something different, saying that it was definitely time to make the break and go… and he said something about having saved up some money, a lot of money.'

'Maybe he has.'

'He doesn't have a job, Dennis. He would never have been able to raise a lot of money,' she stopped for a quick sniff, 'unless he's involved in something. You know, something criminal. That's what I'm worried about. You know what he's like. It would break my mum's heart if anything happened to him again, especially after all that stuff before. And now with Dad gone.'

'Look, I understand you're worried about him. It's only natural. And I know he's had his brushes with the law, but he hasn't been in trouble for a long time now.' Malik was looking at me quizzically now, but I waved him away, intimating that it wasn't business. Not police business, anyway. He stood up and walked off. 'I don't think you should let one drunken phone call get you too concerned. Seriously, Jean.'

'You still see him sometimes, don't you?'

'Yeah, occasionally, but not as often as I'd like.'

'You know, whenever we speak, which I know isn't that often, but whenever we do, he always talks about you. I think he looks up to you. Would you do me a favour? Please. I understand what you're saying about not getting too worried, but would you go round and see him, just to check things out? See that he's OK.'

This was all I needed. 'I really think you're worrying unduly. Danny's no fool. He's done his time. He won't make the same mistake again.'

'Please, Dennis. I'm sure you're busy, but it would mean a lot if you could just check up on him.'

'OK, I'll see what I can do, but I'm sure it's nothing.'

'Thanks. I really appreciate it.' And it sounded like she did.

I took her number in Leeds and said I'd get back to her one way or another in the next few days. We talked for a few moments longer, but the conversation was stilted and uncomfortable. Far too much water had passed under the bridge, and I was happy to hang up. Jean Ashcroft had been a good-looking girl once upon a time, and good company too, but now she was nothing more than a half-forgotten part of my past. Danny had really fucked up by talking to her. He'd seemed fine the other night at the pub quiz. We'd had a few drinks, a few laughs, and had even come a close second to the winners, and when I'd left him he'd been OK. Not exactly full of the joys of spring, but OK nevertheless. It was clear, however, that being cooped up at home for much of the time, with just himself for company, was making him seriously paranoid, and that was dangerous. Fuck knows what he'd do if they ever really got close. I was going to have to give him a good talking to. Knock some sense into him. Get him to calm down.

What was it that American president once said? The only thing we have to fear is fear. Well, Danny feared fear, and it was beginning to make him a liability.

At 11.55 that morning the results from the lab came back confirming that hair samples found on the shirt belonged to Mark Wells, and that it could safely be surmised that the shirt belonged to him.

At 12.10, the questioning of Mark Wells by DCI Knox and DI Welland recommenced. The suspect still denied any involvement in the crime and became hysterical when told of the new evidence against him, at one point attempting to assault both the officers present. He had to be physically restrained before questioning could continue. His solicitor then requested some time alone with his client to discuss these new developments, and this was granted.

At 12.35, the questioning once again resumed, Wells's solicitor sticking to the position that his client had had nothing to do with the murder of Miriam Fox. However, neither he nor Wells could offer any realistic explanation as to why the shirt had been found so close to the murder scene covered in the victim's blood. Wells suggested that it must have been stolen.

At 1.05, twenty-seven-year-old Mark Jason Wells was formally charged with the murder of eighteen-year-old Miriam Ann Fox. For the second time that day, he had to be physically restrained from attacking his interrogators. During the ensuing altercation, his solicitor was accidentally struck in the face by Wells and required medical treatment for a bloody nose. In a rare moment of wit, DS Capper later claimed this to be a double result for the Metropolitan Police.
