“You’ve just told me you don’t think he’s really gone to Scotland!”

“The fact that the door of his flat’s been closed ever since you’ve been watching it suggests he’s gone somewhere.”

Strike dropped tea bags into two mugs.

“I don’t buy the friend’s funeral bit, but it wouldn’t surprise me if he’d popped back to Melrose to try and beat some cash out of his demented mother. That could easily be our Donnie’s idea of holiday fun.”

“One of us should be there for when he comes back—”

“One of us will be there,” said Strike soothingly, “but in the meantime, I want you to switch to—”

“Brockbank?”

“No, I’m doing Brockbank,” said Strike. “I want you to have a bash at Stephanie.”

“Who?”

“Stephanie. Whittaker’s girl.”

“Why?” asked Robin loudly, as the kettle boiled in its usual crescendo of rattling lid and rambunctious bubbles, condensation steaming up the window behind it.

“I want to see whether she can tell us what Whittaker was doing the day Kelsey was killed, and on the night that girl got her fingers hacked off in Shacklewell. The third and the twenty-ninth of April, to be precise.”

Strike poured water on the tea bags and stirred in milk, the teaspoon pinging off the sides of the mug. Robin was not sure whether she was pleased or aggrieved by the suggested change to her routine. On balance, she thought she was glad, but her recent suspicions that Strike was trying to sideline her were not easily dispelled.

“You definitely still think Whittaker could be the killer?”

“Yep,” said Strike.

“But you haven’t got any—”

“I haven’t got any evidence for any of them, have I?” said Strike. “I’m just going to keep going until I either get some or clear all of them.”

He handed her a mug of tea and sank down on the mock-leather sofa, which for once did not fart beneath him. A minor triumph, but in the absence of others, better than nothing.

“I hoped I’d be able to rule out Whittaker on how he’s looking these days,” said Strike, “but, you know, it could’ve been him in that beanie hat. I know one thing: he’s exactly the same bastard he was when I knew him. I’ve blown it completely with Stephanie, she’s not going to talk to me now, but you might be able to do something with her. If she can give him an alibi for those dates, or point us towards someone else who can, we’ll have to rethink. If not, he stays on the list.”

“And what are you going to be doing while I’m on Stephanie?”

“Sticking with Brockbank. I’ve decided,” said Strike, stretching out his legs and taking a fortifying drink of tea, “I’m going into the strip club today, find out what’s happened to him. I’m tired of eating kebabs and hanging round clothes shops waiting for him to show up.”

Robin did not say anything.

“What?” said Strike, watching her expression.

“Nothing.”
