arol pushed past the two men and stared uncomprehendingly at the carnage before her.

"You lot took your time," Tony gasped. As he passed out, the last thing he heard was his own hysterical laughter.

Carol pushed open the door of the side ward. Tony was propped up on a pile of pillows, the left side of his face swollen and bruised.

"Hi," Tony said, a wan half-smile the best he could manage without too much pain.

"Come on in."

Carol closed the door behind her and sat down on a chair by the bed.

"I brought you some bits and pieces," she said, dumping a plastic bag and a padded envelope on the coverlet.

Tony reached out for the bag. Carol winced inside as she saw the bracelet of bruises round his inflamed wrists. He took out a copy of Esquire, a can of Aqua Libra, a tin of pistachio nuts and a Dashiel Hammett omnibus. Thanks," he said, surprised by how her choice touched him.

"I wasn't sure what you liked," she said defensively.

"Then you're obviously a good guesser. The perfect task- force officer."

"If a little slow on the uptake," Carol said bitterly.

Tony shook his head.

"John Brandon was here earlier. He told me how you worked it all out. I don't see how you could have got there any quicker."

"I should have realized sooner that you wouldn't have done a disappearing act at such a crucial time. Come to that, I should have realized as soon as I saw that profile that you could be a target and taken steps to protect you."

"Bollocks, Carol. If anyone should have realized that, it was me. You did a bloody good job."

"No. If I'd been on the ball, we'd have got there in time to save you having to ... to do what you did."

Tony sighed.

"You mean, you'd have saved Angelica's life? For what?

Years in a secure mental hospital? Look on the bright side, Carol.

You've saved the state a fortune. No expensive trial, no years of incarceration and treatment to pay for. Shit, they'll probably give you a medal. "

"That's not what I meant. Tony," Carol said.

"I meant you wouldn't have to live with the knowledge that you've killed someone."

"Yes, well, I can't pretend it was the perfect outcome, but I'll learn to live with it." He forced a smile.

"Don't take this the wrong way, but the first thing I'm going to do when I can walk again is go out and buy you a new mac," he said.

"Every time I look at that coat of yours, I get the urge to scream."

"Why?" Carol frowned in puzzlement.

"Didn't you know? She was wearing the identical mac when she turned up on the doorstep. That way, if she left any fib res at the scene.

Forensic would assume they'd come from you. "

"Terrific," Carol said ironically.

"How are the ankles, by the way?"

Tony pulled a face.

"I don't think I'll ever play the violin again. I managed to make it to the loo on crutches, but I had to sit on the edge of the bath to pee. They're saying there probably won't be any permanent damage, but it'll take a while for the torn ligaments to heal. How was your day?"

Carol pulled a face.

"Grisly. I suspect you'd have been in your element. You were right about keeping the fantasy alive. She, he, it, had tapes of all the telephone-sex conversations she'd had with her victims, and she'd stolen the outgoing message tapes from the men who had answering machines.

"It took the boffins a little while to crack the computer stuff. We didn't have anybody who really knew what they were doing, but my brother Michael came in and sorted it out for us."

Tony gave a twisted smile.

"I didn't want to say anything at the time, but for a wild moment, I actually wondered about your brother."

"Michael? You're kidding!"

Embarrassed, Tony nodded.

"It was when you posited the idea of the computer manipulation of the videos. Michael had the expertise to do that, no question. He's in the right age group, he lives with a woman but not in a sexual relationship, he's got access to all the information the killer needed about the way the police and forensic scientists work, his job is in the general area where I'd expect the killer to work, and he was in a position to know exactly what the police were up to and be involved in the investigation. If we hadn't caught Angelica when we did, I'd have been scrounging an invitation to dinner to check him out."

Carol shook her head.

"See what I mean about being- slow on the uptake? I had access to all the same information as you, and Michael never even crossed my mind as a possibility."

"Not so surprising. You know him well enough to know he's not a psychopath."

Carol shrugged.

"Do I, though? It wouldn't be the first time a close family member, a wife even, has made the same mistake."

"Usually, they're either deluding themselves or they're emotionally unstable and dependent on the killer in some way. Neither of which would have applied in this case." He gave a tired smile.

"Anyway, tell me about what your Michael uncovered."

"The computer was a total gold mine She'd kept her own diary of the stalking and the murders. It even says that she wanted it published after her death. Can you beat that?"

"Easily," Tony said.

"Remind me to show you some of the academic papers I've got on the subject of serial killers."

Carol shivered.

"Thanks, but no thanks. I got a printout of the diary for you. I figured you'd be interested." She gestured to the envelope.

"It's in there. Also, as you'd surmised, she had video-taped the killings, and as I suggested, she'd imported them into her computer and manipulated the images to keep the fantasy alive. It was absolutely gruesome. Tony. It went way beyond nightmare."

Tony nodded.

"I won't say you get used to it, because you never do if you're going to be any use at this job. But you do get to the stage where you can lock it away, so it doesn't jump out and wreck your head unawares."

"Oh, yeah?"

"That's the theory. Ask me again in a few weeks," he said grimly.

"Was there anything in there about how she chose her victims?"

"Just a fucking bit," Carol said bitterly.

"She'd been at this for months before she even picked out the first victim. She worked for the phone company, a computer systems manager. Apparently, she used to work for a small private phone company back in Seaford, which gave her the experience to get the job in Bradfield. She was what they call a super-user of the computer system, so she had access to every piece of data in there. She used the phone company's computer to extract all the residential numbers who had made regular calls to sex chat lines in the past year." Carol paused, letting the obvious question hang in the air.

"It was research," Tony said wearily.

"I published a paper on the role of chat lines in the development of fantasies among serial offenders. Someone should have told Angelica not to jump to conclusions."

Reading his remark as a veiled reproach, Carol moved on.

"She cross-referenced that against the electoral roll and came up with men who lived alone. Then she just checked them out by watching their houses. She had a clear picture of the physical type she wanted, and she wanted one with his own house, a decent income and good career prospects. Can you believe it?"

"Only too well," Tony said grimly.

"Her rationale was that she never wanted to kill them, she only wanted to love them. But they made her murder because they betrayed her. She kept telling herself that what she really wanted was a man who would love her and live with her."

Don't we all, Carol thought but didn't say.

"Anyway, once she'd decided on the likely candidate, she paved the way with the dirty phone calls. She got them on the hook that way, on account of all you sleazy men can't resist anonymous sex."

"Ouch," Tony said, wincing.

"In my defence, I'd have to say that a large part of my interest was purely academic. I was interested in the psychology of a woman who would do what she did on the phone."

Carol smiled tightly.

"At least I know now that you were telling the truth when you said you didn't know the woman who was leaving the sexy messages on your answering machine."

Tony looked away.

"And the discovery that a man you were attracted to was getting his rocks off in kinky telephone sex with a stranger must have been delightful for you."

Carol was silent, unsure what to say.

"I've heard the tapes now," she admitted.

"Yours are very different from the others. You were clearly uncomfortable a lot of the time. Not that it's any of my business."

Still unable to meet her eyes. Tony spoke, his voice clipped and clinical.

"I have a problem with sex. To be precise, I have problems with achieving and maintaining an erection. The honest truth is that only part of me was treating the calls with professional interest.

The other part of me was trying to use them as a kind of therapy. I know that makes me sound like a pervert, but part of the trouble with doing the job I do is that it's virtually impossible to find a therapist I can respect and trust who isn't connected in some way to the world I work in. And however much they verbally espouse the principle of client confidentiality, I've always been reluctant to expose myself to the risk. "

Realizing the difficulty Tony had had in making his confession, Carol reached out for his hand and covered it lightly with hers.

"Thank you for telling me that. It won't go any further. And if it makes you feel any better, the only people who have heard the tapes in full are me and John Brandon. You don't have to worry about what people are saying about you behind your back within the force."

"That's something, I suppose. So, go on. Tell me about Angelica's phone calls to the other victims."

"It was obvious that the men thought this was sex without any commitment or comeback. Angelica's analysis was completely different.

She'd convinced herself that their responses meant they were falling in love with her. Unfortunately for the guys, they decided otherwise.

As soon as they showed any interest in another woman, they signed their death warrants. Apart from Damien, that is. She killed him to teach us a lesson. You were going to be the other lesson. "

Tony shuddered.

"No wonder she had to go abroad for the sex-change operation. The NHS psychologists she saw must have had a field day with her attitudes and aspirations."

"Apparently, they decided she was not an appropriate candidate for a sex change because of her lack of insight into her sexuality. They concluded that she was a gay man who couldn't cope with his sexuality because of cultural and family conditioning. They recommended counselling with a sex therapist rather than a sex change. There was an ugly scene at the time. He threw one of the psychologists through a glass door," Carol revealed.

"Pity they didn't press charges," Tony said.

"Yes. And you'll be pleased to hear they're definitely not going to charge you."

"I should think not! Like I said, think of the taxpayers' money I've saved. Maybe we should have dinner to celebrate when I get out of here?" he asked tentatively.

"I'd like that. There is one other good thing that came out of all of this," Carol said.

"What's that?"

"Penny Burgess took the day off yesterday to go walking in the dales.

Apparently, her car broke down and she got stranded in the middle of a forest all night. She missed the whole shooting match. There's a dozen by-lines in the Sentinel Times tonight, and not a single one of them is hers! " .

Tony lay back and stared at the ceiling. Papering over the cracks, that's what they were doing. He suspected Carol knew that as well as he did, and he wasn't sorry for the effort she was making. But he'd had enough for now. He closed his eyes and sighed.

"Oh God, I'm sorry," Carol said, getting to her feet.

"I wasn't thinking. You must still be exhausted. Look, I'm out of here. I'll leave you this stuff to read when you feel up to it. I could drop in tomorrow if you like ..."

"I think I'd like that," Tony said wearily.

"It just comes over me in waves sometimes."

He heard her feet cross the floor and the click of the door opening.

"Take care," Carol said.

The door closed behind her and Tony pushed himself back up till he was leaning against the pillows. He reached for the padded envelope.

While he couldn't cope with conversation, his curiosity wouldn't let him ignore Angelica's diary. He pulled out a thick wedge of A4 paper.

"Let's see what you were really made of," he said softly.

"What's the story? How did you justify, what did you hide behind?" Hungrily, he began to read.

Wading through the outpourings of the psychologically damaged was normally a routine exploratory experience for Tony. But this was different, he realized after only a few paragraphs. At first, he couldn't pin down what it was.

The writing was more literate, more controlled and more immediate than most of their ramblings, but that didn't explain why his response was so different. He moved on a few pages, fascinated and repelled equally. It was no more or less self-obsessed than other things he'd read, but there was a chilling relish here that was unusual. Most killers whose writings he'd read had gloried far more in their own bloody role, reflecting less on what they'd done to their victims and its effect on them, but here was someone who identified herself as much in terms of them. But even that couldn't entirely explain why he felt so unsettled by what he was reading.

Whatever it was, it was making him more reluctant to continue the more he read, the opposite to his normal response. He'd been so obsessively keen to get inside the head of the killer he'd dubbed Handy Andy, but now it was laid out before him, it was as if he didn't want to know.

As he forced himself to read on, mentally chalking up the correct assumptions he'd made in his profile, it eventually dawned on him that what he was feeling was personal. These words were touching him in ways he'd never experienced before because the life outlined in these pages had touched him with a directness he'd never known before. These were the footsteps of his own personal nemesis that he was tracing, and it was an uncomfortable journey.

He tossed the papers to one side, unable to keep going, seeing his own fate mirrored in the broken bodies Angelica had meticulously described. The trouble with being a psychologist was that he knew exactly what was happening to him. He knew he was still in shock, still deep in denial. Although he couldn't get the events in the cellar out of his mind, there was still a distance between him and the memory, as if he were watching them from a long way off. One day the horror of the previous night was going to come roaring back in stereo, splashed across his inner eye in Cinemascope. Knowing that, this numbness was a blessing.

Already, he knew, his answering machine would be crammed with lucrative offers for the story of how the hunter turned killer. One day, he was going to have to tell that story. He hoped he'd have the strength to save it for a psychiatrist.

It was no comfort to rationalize that having been the target of one serial killer, he was statistically unlikely ever to find himself in that position again. All he could think of was the hours in the cellar, dredging his experience and knowledge for the magic words that would give him a few minutes longer to try for the key to his freedom.

Then that kiss. The whore's kiss, the killer's kiss, the lover's kiss, the saviour's kiss, all rolled into one. A kiss from the mouth that had been seducing him for weeks, the mouth whose words had given him hope for his future, only to leave him finally stranded in this place. He had spent his working life worming his way into the heads of those who kill, only to end up one of them, thanks to a Judas kiss.

"You've won, haven't you, Angelica?" he said softly.

"You wanted me, and now you've got me."
