She turned away and went inside, making her way up the threadbare staircase to the first floor, conscious that her foot was playing up again. It was the second time she’d been shot in the space of five years. Add to that the fact that she’d killed a man and that two of her colleagues, one a lover, had been murdered, and it was hardly a wonder she had such a high profile.

The Black Widow, they’d called her at one time. Perhaps they still did, she wasn’t entirely sure. Either way, people tended to keep their distance from her, as if she was some kind of jinx, and because of this she’d become something of a loner. She was a nomad too, unable to settle fully in any one job. She’d already left the force once before coming back a year later and joining Soca, the Serious Organised Crime Agency, where she’d lasted a year before returning to where she’d first been a wet-behind-the-ears DC, at Islington CID. But regular detective work hadn’t lived up to her expectations either, so when a slot on CMIT had come up with a chance for promotion, she’d jumped at it. Perhaps her profile hadn’t done her as much harm as she’d thought, because she’d got the job, and was making a pretty decent go of it too, although she preferred detective work to the management of others.

The reinforced door to Andrew Kent’s flat had been propped open with a telephone directory and there was a vague smell of stale sweat coming from inside, mixed with cheap air freshener. It was a cramped little one-bed place with a narrow corridor connecting the rooms, and it was already busy with members of the team, working two and three to a room, meticulously going through Kent’s possessions. They would take this place apart piece by piece over the next few days until they’d searched every last inch of it. A man who’d brutally murdered five women was always going to keep some kind of trophy from his experiences — a means of helping him to relive them — and however well he might have hidden it, they’d find it. Because now they had him in custody, time was on their side.
