In the incident room, she found that the morning briefing was already going on. Superintendent Lynley glanced her way in the middle of listening to something being said by Winston Nkata, and he did not look particularly chuffed as his gaze traveled beyond her to the clock on the wall.

Winston was saying, “…works of wrath or vengeance, ’cording to what the lady at Crystal Moon told me. She looked it up in a book. She handed over a register of shop visitors wanting to be on their newsletter list, and she’s got credit card purchases and postal codes of customers as well.”

“Let’s match the postal codes with the body sites,” Lynley said to him. “Do the same with the register and the credit card purchases. We may get some joy there. What about Camden Lock Market?” Lynley looked towards Barbara. “What did you get from that stall, Constable? Did you stop there this morning?” Which was his way of saying, I trust that’s your reason for walking in here late.

Barbara thought, Holy hell. The run-in with Azhar had wiped every other consideration from her mind. She fumbled round her head for an excuse, but the course of wisdom brought her back from the brink at the last moment. She opted for the truth. “I dropped the ball on that,” she admitted. “Sorry, sir. When I was finished with Colossus yesterday, I…Never mind. I’ll get on to it directly.”

She saw the looks exchanged round her. She saw Lynley’s lips get thin for an instant, so she went on hastily in an attempt to smooth over the moment. “I think the direction we need to take is Colossus anyway, sir.”

“Do you.” Lynley’s voice was even, too even, but she chose to ignore that.

She said, “I do. We’ve got possibles and counting over there that need looking into. Aside from Jack Veness, who seems to know something about everyone, there’s a bloke called Neil Greenham who’s a bit overly helpful. He had a copy of the Standard that he was dead chuffed to show me, by the way. And that Robbie Kilfoyle-he was in reception yesterday, playing cards with that kid?-he volunteers in the kit room. He does lunch deliveries as a second job-”

“Van?” Lynley asked.

“Bike. Sorry,” Barbara said regretfully. “But he admitted he’s aiming for a real job at Colossus if it expands across the river, which gives him a motive to make someone else look-”

“Killing off the customers is hardly going to get him that, is it, Havers?” John Stewart cut in acerbically.

Barbara ignored the dig, going on to say, “His competition could be a bloke called Griff Strong, who’s lost his last two jobs in Stockwell and Lewisham because, according to him, he didn’t get along with female coworkers. That’s four possibles, and they’re all in the age range of the profile, sir.”

“We’ll look into them,” Lynley agreed. And just as Barbara thought she’d redeemed herself, Lynley asked John Stewart to hand out that assignment and he went on to tell Nkata to dig round in the background of Reverend Bram Savidge and to deal with the goings-on at Square Four Gym in Swiss Cottage, and a car repair shop in North Kensington, while he was at it. Then he made additional assignments involving the taxi driver who’d called 999 about the body in the Shand Street tunnel and the abandoned car where that body had been deposited. He took in a report about the cookery schools in London-no Jared Salvatore enrolled in any of them-before he turned to Barbara and said, “I’ll see you in my office, Constable.” He strode out of the incident room with a “Get on with it, then” to the rest of the team, leaving Barbara to follow. She noted that no one looked at her as she trailed after Lynley.

She found herself scurrying to keep up with him, and she didn’t like the dog-and-master feeling this evoked. She knew she’d muffed it by forgetting to check the stall in Camden Lock Market and she supposed she deserved a dressing-down for that, but on the other hand, she’d given them a new direction with Strong, Greenham, Veness, and Kilfoyle, hadn’t she, so that had to count for something.

Once in the superintendent’s office, however, it seemed that Lynley didn’t see things this way. He said, “Shut the door, Havers,” and when she had done so, he went to his desk. Instead of sitting, however, he merely leaned his hips against it and faced her. He gestured her to a chair, and he loomed above her.

She absolutely loathed the way this made her feel, but she was determined that loathing would not rule her. She said, “Your picture was on the front page of the Standard, sir. Yesterday afternoon. So was mine. So was Hamish Robson’s. We were standing just outside of the Shand Street tunnel. You were named. That’s not good.”

“It happens.”

“But with a serial killer-”

Lynley broke in. “Constable, tell me this: Are you deliberately attempting to shoot yourself in the foot or is all of this part of your unconscious?”

“All of this…? What?”

“You were given the assignment. Camden Lock Market. On your route home, for the love of God. Or, for that matter, on your route here. Do you realise how you appear to the others when-as you put it-you ‘drop the ball’? If you want your rank back, which I assume you do and which I also assume you know depends upon your being able to function as part of a team, how do you expect to achieve that if you’re going to make your own decisions about what’s important in this investigation and what is not?”

“Sir, that’s not fair,” Barbara protested.

“And this isn’t the first time you’ve operated on your own,” Lynley said, as if she hadn’t spoken. “If ever an officer had a professional death wish…What the hell were you thinking? Don’t you see I can’t keep running interference for you? Just when I begin to think I’ve got you sorted, you begin it all again.”

“All what?”

“Your infernal bloody-mindedness. Your taking the reins in your hands instead of the bit in your mouth. Your constant insubordination. Your unwillingness even to make a pretence of being part of a larger team. We’ve been through this before. Time and again. I’m doing my best to protect you, but I swear to you if this doesn’t stop…” He threw up his hands. “Get over to Camden Lock Market, Havers. To Wendy’s Rainbow or whatever the hell it was called.”

“Wendy’s Cloud,” Barbara said numbly. “But she may not be open because-”

“Then you can bloody well track her down! And until you do, I don’t want to see your face, hear your voice, or know you exist on the planet. Is that clear?”

Barbara stared at him. Her stare turned into an observation. She’d worked with Lynley for long enough to know how wildly out of character his outburst was, no matter how richly she deserved being sorted. She did a mental riffling through the reasons he was on the edge: another murder, a row with Helen, a run-in with Hillier, trouble with his younger brother, flat tyre on the way to work, too much caffeine, not enough sleep…But then it came to her, as easily as knowing who Lynley was.

She said, “He’s got in touch with you, hasn’t he? He saw your name in the paper and he bloody got in touch.”

Lynley observed her for a moment before making his decision. He moved round his desk. There he took a paper out of a manila folder. He handed it to her, and Barbara saw it was a copy of an original, which, she presumed, was already on its way to forensics.

THERE IS NO DENIAL, ONLY SALVATION was printed neatly in block letters on a single line across the page. Beneath this was not a signature but rather a marking that looked not unlike two squared-off but separated sections of a maze.

“How’d it get here?” Barbara asked, returning it to Lynley.

“By post,” Lynley said. “Plain envelope. Same printing.”

“What d’you make of the marking? A signature?”

“Of sorts.”

“Could be some bugger just wanting to play games, couldn’t it? I mean, he doesn’t actually tell us anything to show he knows something only the killer would know.”
