hen Damien Connolly failed to turn up at the start of his shift as local information officer in F Division's station on the south side of the city, the duty sergeant hadn't been unduly worried. Although PC Connolly was one of the best collators in the force, and a trained HOLMES officer, he was a notoriously bad timekeeper. At least twice a week, he came hurtling through the doors of the station a good ten minutes after his shift was due to start. But when he still hadn't shown up half an hour after he was due on duty. Sergeant Claire Bonner felt a twinge of irritation. Even Connolly had enough sense to realize that if he was going to be more than fifteen minutes late, he had to phone in. Today of all days as well, when headquarters were demanding a full turnout of HOLMES officers on the serial-killer investigation.

Sighing, Sgt Bonner checked Connolly's home number in her files and dialled it. The phone rang and rang, till finally it was automatically disconnected. She felt a prickle of concern. Connolly was something of a loner outside the job. He was quieter and maybe more thoughtful than most of the officers on Sgt Bonner's relief, always keeping his distance when he joined in the social life of the station. As far as she was aware, there was no girlfriend in whose bed Connolly might have overslept. His family were all up in Glasgow, so there were no relatives to try locally. Sgt Bonner cast her mind back. Yesterday had been a day off for the relief. When they'd knocked off from the previous night shift, Connolly had come for breakfast with her and half a dozen of the other lads. He'd not said anything about having plans for his time off other than catching up on his kip and working on his car, an elderly Austin Healey roadster.

Sgt Bonner went through to the control room and had a word with her opposite number, asking him to have one of the patrol cars swing round by Connolly's house to check he wasn't ill or injured.

"See if they can check the garage, make sure that bloody car of his hasn't come off the jack with him underneath," she added as she went back to her desk.

It was after eight when the control room sergeant appeared in her office.

"The lads have checked Connolly's house. No answer to the door. They had a good scout round, and all the curtains were open.

Milk on the doorstep. No sign of life as far as they could make out.

There was only one thing a bit odd that they could see. His car was parked on the street, which isn't like him. I don't have to tell you, he treats that motor like the crown jewels. "

Sgt Bonner frowned.

"Maybe he's got somebody stopping with him? A relative, or a girlfriend? Maybe he's let them stick their car in the garage?"

The control room sergeant shook his head.

"Nope. The lads had a look in the garage window, and it was empty. And don't forget the milk."

Sgt Bonner shrugged.

"Not a lot more we can do, then, is there?"

"Well, he's over twenty-one. I'd have thought he'd have more sense than to go on the missing list, but you know what they say about the quiet ones."

Sgt Bonner sighed.

"I'll have his guts for garters when he shows his face. By the way, I've asked Joey Smith to stand in for him in the collator's office for this shift."

The control room sergeant cast his eyes upwards.

"You really know how to make a man's day, don't you? Couldn't you have got one of the others? Smith can barely manage the alphabet."

Before Sgt Bonner could argue the toss, there was a knock at the door.

"Yeah?" she called.

"Come in."

A PC from the control room entered hesitantly. She looked faintly sick.

"Skip," she said, the worry in her voice obvious from the single word.

"I think you'd better have a look at this." She held out a fax, the bottom edge ragged where it had been torn hastily off the roll.

Being nearer, the control room sergeant took the flimsy sheet and glanced at it. He drew in his breath sharply, then closed his eyes for a moment. Wordlessly, he handed the fax to Sgt Bonner.

At first, all she saw was the stark black and white of the photograph. For a moment, her mind automatically protecting her from horror, she wondered why someone had gone over her head and reported Connolly missing. Then her eyes translated the marks on the paper into words.

"Urgent fax to all stations. This is the unidentified murder victim discovered yesterday afternoon in the back yard of the Queen of Hearts public house. Temple Fields, Bradfield. Photograph to follow later this a.m. Please circulate and display. Any information to DI Kevin Matthews at Scargill Street Incident Room, ext. 24 j 6."

Sgt Bonner looked bleakly at the other two officers. "There isn't any doubt about it, is there?"

The PC looked at the floor, her skin pale and clammy. "I don't think so, skip," she said.

"That's Connolly. I mean, it's not what you'd call a good likeness, but it's definitely him."

The control room sergeant picked up the fax.

"I'll get on to DI Matthews right away," he said.

Sgt Bonner pushed her chair back and stood up.

"I'd better go round to the morgue. They're going to need a formal identification as soon as possible so they can get weaving."

"This makes it a whole new ball game," Tony said, his face sombre.

"It certainly ups the stakes," Carol said.

"The question I'm asking myself is whether or not Handy Andy knew he was giving us a bobby," Tony said softly, swinging round in his chair to stare out of the window at the city rooftops.

"Sorry?"

He gave a twisted smile and said,

"No, it's me who should apologize.

I always give them a name. It makes it personal. " He swung back to face Carol.

"Does that bother you?"

Carol shook her head.

"It's better than the station nickname."

"Which is?" Tony asked, eyebrows raised.

"The Queer Killer," Carol said, her distaste clear.

"That begs a lot of questions," Tony said noncommittally. "But if it helps them deal with their fear and anger, it's probably no bad thing."

"I don't like it. It doesn't feel personal to me, calling him the Queer Killer."

"What does make it personal to you? The fact that he's taken one of yours now?"

"I felt like that already. As soon as we got the second murder, the one I was handling, I was convinced we were dealing with a serial offender. That was when it got personal for me. I want to nail this bastard. I need to. Professionally, personally, whatever." The cold vehemence in Carol's voice gave Tony confidence. This was a woman who was going to pull out all the stops to make sure he had what he needed to do his job. Her tone of voice and the words she'd chosen were also a calculated challenge, showing him she didn't give a damn what he made of her desire. She was just what he needed. Professionally, at any rate.

"You and me both," Tony said.

"And together, we can make it happen.

But only together. You know, the first time I got directly involved in profiling, it was a serial arsonist. After half a dozen major fires, I knew how he was doing it, why he was doing it, what was in it for him. I knew exactly the kind of mad bastard he was, yet I couldn't put a name or a face to him. It drove me crazy with frustration for a while. Then I realized it wasn't my job to do that.

That's your job. All I can do is to point you in the right direction. "

Carol smiled grimly.

"Just point, and I'll be off like a gun dog,"

she said.

"What did you mean when you said you wondered whether he knew Damien Connolly was a bobby?"

Tony ran a hand through his hair, leaving it spiky as a punk's.

"OK.We've got two scenarios here. Handy Andy may not have known Damien Connolly was a bobby. It may be nothing more than a coincidence, a particularly unpleasant coincidence for his colleagues, but a coincidence nevertheless. That's not a scenario I'm happy with, however, because my reading, based on the little I know so far, is that these aren't random victims snatched by chance. I think he chooses his victims with care, and plans thoroughly. Would you agree with that? "

"He doesn't leave things to chance, that's obvious," Carol said.

"Right. The alternative is that Handy Andy knows full well that his fourth victim is a policeman. That in itself leads to two further possibilities. One: Handy Andy knew he'd killed a copper, but that fact is supremely irrelevant to the meaning of the killing for him.

In other words, Damien Connolly fulfilled all the other criteria that Andy needs from his victims, and he would have died at this point whether he was a bobby or a bus driver.

"The other scenario is the one I like best, though. The fact that Damien was a copper is a crucial part of the reason why Handy Andy chose him as his fourth victim."

"You mean he's thumbing his nose at us?" Carol asked.

Thank God she was quick. That was going to make the job so much simpler. She'd done well to get as far up the ladder as she had, given she had looks as well as brains. Either attribute without the other would have made promotion easier.

"That's certainly a possibility," Tony acknowledged.

"But I think it's more likely to be about vanity. I think he'd started to get pissed off with Detective Superintendent Cross's refusal to acknowledge his existence In his own eyes, he's very successful at what he does. He's the best. And he deserves recognition. And that desire for recognition has been thwarted by the police's refusal to admit there's only one offender behind these killings. OK, so the Sentinel Times has been speculating about a serial killer since the second victim, but that's not the same as being given the official accolade by the police themselves.

And I may have unwittingly added fuel to the fire after the third killing. "

"You mean, the interview you did with the Sentinel Times?"

"Yeah. My suggestion that it was possible there were two killers at work will have made him angry that he wasn't being acknowledged as the master of his craft."

"Dear God," Carol said, torn between revulsion and fascination.

"So he went out and stalked a police officer so we'd take him seriously?"

"It's a possibility. Of course, it can't have been just any police officer. Even though making his point to the powers that be is important to Handy Andy, the prime directive is still to go for victims who fulfill his very personal criteria."

Carol frowned.

"So what you're saying is that there's something about Connolly that makes him different from most other coppers?"

"Looks like it."

"Maybe it's the sexuality thing," Carol mused.

"I mean, there aren't many gays in the force. And those that there are tend to be so deep in the closet you could mistake them for a clothes hanger."

"Whoa," Tony laughed, holding up his hands as if to fend her off.

"No theorizing without data. We don't know yet whether Damien was gay.

What might be useful, though, is to find out what shifts Damien worked recently. Say, the last two months. That'll give us some idea of the times he was at home, which might help the officers who'll be questioning his neighbours. Also, we should be asking around the other officers on his relief, to check out whether he always left alone, or if he ever gave anyone a lift home. We need to find out everything there is to know about Damien Connolly both as a man and as a bobby. "

Carol pulled out her notebook and scribbled a reminder to herself.

"Shifts," she muttered.

"There's something else this tells us about Handy Andy," Tony said slowly, reaching for the idea that had just swum into his consciousness.

Carol looked up, her eyes alert.

"Go on," she said.

"He's very, very good at what he does," Tony said flatly. "Think about it. A police officer is a trained observer. Even the thickest plod is a lot more alert to what's going on around them than the average member of the public. Now, from what you've told me, Damien Connolly was a bright lad. He was a collator, which means he was even more on the ball than most officers. As I understand it, a collator's job is to act like the station's walking encyclopaedia. It's all very well having all the local information about known villains and MOs on file cards, but if the collator isn't sharp, then the system's worthless, am I right?"

"Spot on. A good collator is worth half a dozen bodies on the ground," Carol said.

"And by all accounts, Connolly was one of the best."

Tony leaned back in his chair.

"So if Handy Andy stalked Damien without setting any alarm bells ringing, he must be bloody good. Face it, Carol, if somebody was tailing you on a regular basis, you'd pick them up, wouldn't you?"

"I bloody hope so," Carol said drily.

"But I'm a woman. Maybe we're just a bit more on our guard than the blokes."

Tony shook his head.

"I think a copper as smart as Damien would have noticed anything other than a very professional tail."

"You mean we might be looking for someone who's in the Job?" Carol demanded, her voice rising as she spoke the unthinkable.

"It's a possibility. I can't pitch it more strongly than that till I've seen all the evidence. Is that it?" Tony asked, nodding towards the cardboard box Carol had deposited by the door of his office.

"That's some of it. There's another box and some folders of photographs still in the car. And that's after some serious editing."

Tony pulled a face.

"Rather you than me. Shall we go and fetch it, then?"

Carol stood up.

"Why don't you get started while I go and get the rest?"

"It's the photographs I want to look at first, so I might as well come and help," he said.

"Thanks," Carol said.

In the lift, they stood on opposite sides, both conscious of the other's physical presence. That's not a Bradfield accent," Tony remarked as the doors slid shut. If he was going to work successfully with Carol Jordan, he needed to know what made her tick, personally as well as professionally. The more he could find out about her, the better.

"I thought you said you left the detective work to us?"

"We're good at stating the obvious, us psychologists. Isn't that what our critics on the force say?"

Touche. I'm from Warwick, originally. Then university at Manchester and into the Met on the fast track. And you? I'm not great on accents, but I can spot you're a Northerner, though you don't sound like Bradfield either," Carol replied.

"Born and bred in Halifax. London University, followed by a DPhil at Oxford. Eight years in special hospitals. Eighteen months ago, the Home Office head-hunted me to run this feasibility study." Give a little to get a lot. Tony thought wryly. Who exactly was probing whom?

"So we're both outsiders," Carol said.

"Maybe that's why John Brandon chose you to liaise with me."

The lift doors slid open and they walked through the underground car park to the visitors' parking area where Carol had left her car. Tony hefted the cardboard box out of the boot.

"You must be stronger than you look," he gasped.

Carol picked up the folders of photographs and grinned. "And I'm a black belt in Cluedo," she said.

"Listen, Tony, if this maniac is in the Job, what sort of stuff would you expect to find?"

"I shouldn't have said that. I was theorizing ahead of data, and I don't want you to place any weight on it, OK? Strike it from the record," Tony panted.

"OK, but what would the signs be?" she persisted.

They were back in the lift before Tony answered her. "Behaviour that exhibits a familiarity with police and forensic procedure," he said.

"But in itself, that proves nothing. There are so many true-crime books and TV detectives around these days that anyone could know that sort of stuff. Look, Carol, please put it out of your head. We need to keep an open mind. Otherwise the work we do is valueless."

Carol stifled a sigh.

"OK. But will you tell me if you still think that way after you've seen the evidence? Because if it's more than a slim possibility, we might need to rethink the way we're dealing with the enquiry."

"I promise," he said. The lift doors slid open, as if placing their own full stop on the conversation.

Back in the office. Tony slid the first set of photographs out of their folders.

"Before you start, could you fill me in on how you want to pursue this?" Carol asked, notebook at the ready.

"I'll go through all the pictures first, then I'll ask you to take me through the investigation so far. When we've done that, I'll work through the paperwork myself. After that, what I usually do is draw up a profile of each of the victims. Then we have another session with these," he said, brandishing his forms.

"And then I walk out on the high wire and do a profile of the offender. Does that sound reasonable to you?"

"Sounds fine. How long is all that likely to take?"

Tony frowned.

"It's hard to say. A few days, certainly. However, Handy Andy seems to work on an eight-week cycle, and there's no sign that he's accelerating. That's unusual in itself, by the way. Once I've studied the material I'll have a better idea of how in control he is, but I think we've probably got a bit of time to spare before he kills again. Having said that, he may well have already selected his next victim, so we've got to make sure that we keep any progress we make well away from the press. The last thing we want is to be the catalyst for him speeding up the process."

Carol groaned.

"Are you always this optimistic?"

"It goes with the territory. Oh, and one more thing? If you develop any suspects, I'd prefer not to know anything about them at this stage there's a danger that my subconscious will alter the profile accordingly."

Carol snorted.

"We should be so lucky."

That bad, is it? "

"Oh, we've pulled in anybody who's got form for indecent assault or violent of fences against gay men, but none of them looks even a remote possibility."

Tony pulled a sympathetic face then picked up the photographs of Adam Scott's corpse and slowly started going through them. He picked up a pen and moved his A4 pad nearer to him. He glanced up at Carol.

"Coffee?" he asked.

"I meant to ask earlier, but I was too interested in what we were talking about."

Carol felt like a co-conspirator. She had been enjoying their conversation too, in spite of a twinge of guilt that multiple murders shouldn't be a source of pleasure. Talking with Tony was like talking to an equal who had no axe to grind, whose primary concern was finding a path to the truth rather than a way to boost the ego. It was something she'd missed on this case so far. The too," she admitted. " I'm probably approaching the point where coffee is a necessity. Do you want me to go and fetch some? "

"Good God, no!" Tony laughed.

"That's not what you're here for. Wait there, I'll be right back. How do you take yours?"

"Black, no sugar. In an intravenous drip, preferably."

Tony took a large Thermos jug out of his filing cabinet and disappeared. He was back inside five minutes with two steaming mugs and the jug. He handed Carol a mug and gestured towards the Thermos.

"I filled it up. I figured we might be some time. Help yourself as and when."

Carol took a grateful sip.

"Will you marry me?" she asked, mock romantic.
