Strike regretted his witticism in the meeting room, because Robin had returned from a twenty-minute bathroom trip looking white and slightly clammy, a whiff of peppermint revealing that she had cleaned her teeth again. Instead of taking a taxi he had suggested they take a short walk in the fresh air along Broadway to the Feathers, the closest pub, where he ordered them a pot of tea. Personally, he was ready for a beer, but Robin had not been trained up to consider alcohol and bloodshed natural fellows and he felt a pint might reinforce her impression of his callousness.

The Feathers was quiet at half past eleven on a Wednesday morning. They took a table at the back of the large pub, away from a couple of plainclothes officers who were talking in soft voices near the window.

“I told Wardle about our friend in the beanie while you were in the bathroom,” Strike told Robin. “He says he’s going to put a plainclothes man around Denmark Street to keep an eye out for a few days.”

“D’you think the press are going to come back?” asked Robin, who had not yet had time to worry about this.

“I hope not. Wardle’s going to keep the fake letters under wraps. He says it’s playing into this nutter’s hands to release them. He inclines to the view that the killer’s genuinely trying to frame me.”

“You don’t?”

“No,” said Strike. “He’s not that unhinged. There’s something weirder going on here.”

He fell silent and Robin, respecting his thought process, maintained her own silence.

“Terrorism, that’s what this is,” said Strike slowly, scratching his unshaven chin. “He’s trying to put the wind up us, disrupt our lives as much as possible; and let’s face it, he’s succeeding. We’ve got police crawling over the office and calling us into the Yard, we’ve lost most of our clients, you’re—”

“Don’t worry about me!” said Robin at once, “I don’t want you to worry—”

“For fuck’s sake, Robin,” said Strike on a flash of temper, “both of us saw that guy yesterday. Wardle thinks I should tell you to stay home and I—”

“Please,” she said, her early-morning fears swarming back upon her, “don’t make me stop work—”

“It’s not worth being murdered to escape your home life!”

He regretted saying it immediately, as he saw her wince.

“I’m not using it as an escape,” she muttered. “I love this job. I woke up this morning feeling sick about what I told you last night. I was worried you—might not think I’m tough enough anymore.”

“This hasn’t got anything to do with what you told me last night and nothing to do with being tough. It’s about a psycho who might be following you, who’s already hacked a woman to bits.”

Robin drank her lukewarm tea and said nothing. She was ravenous. However, the thought of eating pub food containing any form of meat made sweat break out over her scalp.

“It can’t have been a first murder, can it?” Strike asked rhetorically, his dark eyes fixed on the hand-painted names of beers over the bar. “Beheading her, cutting off her limbs, taking bits of her away? Wouldn’t you work up to that?”
