Havers bristled but said calmly enough, “Never been able to do much with it.”

“Then perhaps someone else can. Do you have a regular hair-dresser, Sergeant?”

Havers put a hand to her chopped-up locks. They were a decent colour. Pine would come closest to describing it, Isabelle decided. But they appeared completely unstyled. Obviously, the sergeant had been cutting her hair herself. God only knew how, although Isabelle reckoned it involved the use of secateurs.

“Well, have you?” Isabelle asked her.

“Not as such,” Havers said.

“You need to find one.”

Havers moved her fingers in a way that suggested she wanted a smoke, rolling a fantasy fag between them. “When, then?” she asked.

“When then what?”

“When am I s’posed to take all of your…suggestions to heart?”

“Yesterday. Not to put too fine a point on it.”

“Straight away, you mean?”

Isabelle smiled. “I see you’re going to be good at reading my every nuance. Now”-and here they were at the real point, the reason that Isabelle had moved them from the desk to the conference table-“tell me. What do you hear from Inspector Lynley?”

“Nothing much.” Havers looked and sounded immediately cagey. “Talked to him a couple times is all.”

“Where is he?”

“Don’t know, do I,” Havers told her. “I expect he’s still in Cornwall. He was walking the coast last I heard. All of it.”

“Quite a hike. How did he seem to you when you spoke to him?”

Havers knotted her unplucked eyebrows, clearly wondering about the line of questioning upon which Isabelle had now embarked. She said, “Like you’d expect someone to seem when he’s had to pull the plug on his wife’s life support. I wouldn’t call him chipper. He was coping, guv. That’s about all.”

“Will he be returning to us?”

“Here? London? The Met?” Havers considered this. She considered Isabelle as well, obviously her mind clicking away with all the possibilities that might explain why the new acting detective superintendent wanted to know about the former acting detective superintendent. Havers said, “He didn’t want the job. He was just doing it temporarily. He’s not into promoting or anything. It’s not who he is.”

Isabelle didn’t like being read. Least of all did she like being read by another woman. Thomas Lynley was indeed one of her worries. She wasn’t averse to having him back on the team, but if that was going to happen, she wanted it to be with her prior knowledge and on her terms. The last thing she desired was his sudden appearance and everyone welcoming him with religious fervor.

She said to Havers, “I’m concerned about his well-being, Sergeant. If you hear from him, I’d like to know it. Just how he is. Not what he says. May I rely on you for that?”

“I suppose,” Havers said. “But I won’t be hearing from him, guv.”

Isabelle reckoned she was lying on both accounts.

MUSIC MADE THE ride bearable. The heat was intense because, while windows nearly the size of cinema screens lined both sides of the vehicle, they did not open. Each of them had a narrow, tilt-out pane of glass at the top, and all of these were open, but that did nothing to relieve what sunlight, weather, and restless human bodies effected within the rolling tube of steel.

At least it was a bendy bus and not one of the double-deckers. Whenever it stopped, both its front door and its back door opened and a gust of air-hot and nasty but still, new air-allowed him to breathe deeply and believe he could survive the ride. The voices in his head kept declaring otherwise, telling him that he needed to get out and get out soon because there was work to do and it was God’s mighty work. But he couldn’t get out, so he was using the music. When he had it coming through his earphones loud enough, it drowned out everything else, voices included.

He would have closed his eyes to lose himself in it: the sweep of the cello and its mournful tone. But he had to watch her and he had to be ready. When she made a move to debark, so would he.

They’d been riding for over an hour. Neither of them should have been there. He had his work, as did she, and when people didn’t do what they were meant to do, the world went amiss and he had to heal it. He was told to heal it, in fact. So he’d followed her, careful not to be seen.

She’d got onto one bus and then onto another and now he could see she was using an A-Z in order to follow the route. This told him that she was unfamiliar with the area through which they were riding, an area that looked to him like much of the rest of London. Terraces of houses, shops with grimy plastic signs above their front windows, graffiti looping letters into meaningless words like killdick boyz, chackers, and porp.

As they wound through town, on the pavements tourists morphed into students with backpacks who themselves became women in black from head to toe, slits for their eyes, in the company of men comfortably dressed in jeans and white T-shirts. And these became African children at play, running in circles beneath the trees in a park. And then for a time, blocks of flats blended into a school, and this in turn dissolved to a collection of institutional-looking buildings from which he turned his gaze. Finally, a narrowing of the street occurred and it then curved and they came into what looked like a village, although he knew it was not a village at all but rather a place that had been a village once. It was another of the multitude of communities consumed over time by the creeping mass of London.

The street climbed a modest hill and then they were among the shops. Mothers pushed prams here, and people mixed. Africans talked to whites. Asians shopped for halal meats. Old-age pensioners sipped Turkish coffee in a café advertising pastries from France. It was a pleasant place. It made him relax, and it almost made him turn his music off.

Up ahead, he saw her begin to stir. She closed her A-Z after carefully turning down the corner of a page. She had nothing with her but her shoulder bag, and she tucked the A-Z into this as she made for the door. He noticed they were coming to the end of the High Street and its shops. A wrought-iron railing atop a brick revetment suggested they had reached a park.

It seemed odd to him that she’d come all this way by bus in order to visit a park, when there was a park-or perhaps more accurately a garden-not two hundred metres from where she worked. True, the day was wretchedly hot and beneath the trees it would be cool and even he looked forward to the cool after that ride in the moving furnace. But if cool had been her intention all along, she could merely have gone into St. Paul’s parish church, which she sometimes did in her lunch hour, reading the tablets on the walls or just sitting near the communion rail to gaze at the altar and the painting above it. Madonna and child, this painting was. He knew that much although-despite the voices-he did not think himself a religious man.

He waited until the last moment to get off the bus. He’d placed his instrument on the floor between his feet, and because he’d watched her so closely as she headed in the direction of the park, he nearly forgot to take it along. That would have been a disastrous mistake, and because he’d come so close to making it, he removed his earphones to silence the music. The flame is come is come is here went round in his head immediately when the music ceased. I call on the birds to feast on the fallen. He blinked hard and shook his head roughly.

There was a gate of wrought iron fully open, at the top of four steps leading into the park. Before mounting these, she approached a notice board. Behind glass, a map of the place was posted. She studied this, but only briefly, as if verifying something that she already knew. Then she went inside the gate and in an instant she was swallowed up by the leafy trees.
