The lady changed her name to Anastassia and died her hair and nobody ever found out were she went, she vanished.

“Is that what you’d like to do, Brittany?” the investigator had asked quietly on the tape Strike had watched later. “You’d like to run away and vanish?”

“It’s just a story!” Brittany had insisted, trying for a scornful laugh, her little fingers twisting together, one leg almost wrapped around the other. Her thin blonde hair had hung lank around her pale, freckly face. Her spectacles had been wonky. She had reminded Strike of a yellow budgerigar. “I only made it up!”

DNA testing would find out soon enough who the woman in the fridge had been, and then the police would trawl backwards to see who Oxana Voloshina—if that was her name—really was. Strike could not tell whether he was being paranoid or not in continuing to worry that the body belonged to Brittany Brockbank. Why had the name Kelsey been used on the first letter to him? Why did the head look so young, still smooth with puppy fat?

“I should be on Platinum by now,” said Robin sadly, checking her watch as she sat back down at the table. One of the office workers beside them seemed to be celebrating her birthday: with much raucous laughter from her colleagues she had just unwrapped a red and black basque.

“I wouldn’t worry about it,” Strike said absently, as his fish and chips and Robin’s plowman’s descended in front of them. He ate silently for a couple of minutes, then set down his knife and fork, pulled out his notebook, looked something up in the notes he had made back in Hardacre’s Edinburgh office and picked up his phone. Robin watched him key in words, wondering what he was doing.

“Right,” said Strike, after reading the results, “I’m going to Barrow-in-Furness tomorrow.”

“You’re—what?” asked Robin, bewildered. “Why?”

“Brockbank’s there—or he’s supposed to be.”

“How do you know?”

“I found out in Edinburgh that his pension’s being sent there and I’ve just looked up the old family address. Someone called Holly Brockbank’s living in the house now. Obviously a relative. She should know where he is. If I can establish that he’s been in Cumbria for the last few weeks, we’ll know he hasn’t been delivering legs or stalking you in London, won’t we?”

“What aren’t you telling me about Brockbank?” Robin asked, her blue-gray eyes narrowing.

Strike ignored the question.

“I want you to stay at home while I’m out of town. Sod Two-Times, he’s got only himself to blame if Platinum cops off with another punter. We can live without his money.”

“That’ll leave us with a single client,” Robin pointed out.

“I’ve got a feeling we’ll have none at all unless this nutter’s caught,” said Strike. “People aren’t going to want to come near us.”

“How are you going to get to Barrow?” asked Robin.

A plan was dawning. Hadn’t she foreseen this very eventuality?

“Train,” he said, “you know I can’t afford a hire car right now.”
