The hazy, clear-skied promise of another summer’s day hadn’t yet translated itself into actual warmth when Robin arrived next morning at the café closest to Chiswell’s house. She could have chosen one of the circular tables outside on the pavement, but instead she huddled down in a corner of the café where she was to meet Strike, hands clasped around her latte for comfort, her reflection in the espresso machine pale and heavy-eyed.

Somehow, she had known that Strike would not be here when she arrived. Her mood was simultaneously depressed and nervy. She would rather not have been alone with her thoughts, but here she was, with only the hiss of the coffeemaker for company, chilly in spite of the jacket she had grabbed on the way out of the house and full of anxiety about the imminent confrontation with Chiswell, who might quibble his bill, after the catastrophe of Strike’s fight with Jimmy Knight.

But that wasn’t all that was worrying Robin. She had woken that morning from a confused dream in which the dark, spike-booted figure of Charlotte Ross figured. Robin had recognized Charlotte immediately when she spotted her at the reception. She had tried not to watch the once-engaged couple as they’d talked, angry with herself for being so sharply interested in what was passing between them, yet, even as she had moved from group to group, shamelessly insinuating herself into conversations in the hope of finding the elusive Elspeth Curtis-Lacey, her eyes had sought out Strike and Charlotte, and when they left the reception together she had experienced a nasty sensation in her stomach, akin to the drop of an elevator.

She had arrived home unable to think of anything else, which had made her feel guilty when Matthew emerged from the kitchen, eating a sandwich. She had the impression that he had not been home long. He subjected the green dress to an up-and-down look very like the one Kinvara had given her. She made to walk past him upstairs, but he had moved to block her.

“Robin, come on. Please. Let’s talk.”

So they had gone into the sitting room and talked. Tired of conflict, she had apologized for hurting Matthew’s feelings by missing the cricket match, and for forgetting her wedding ring on their anniversary weekend. Matthew in turn had expressed regret for the things he had said during Sunday’s row, and especially for the remark about her lack of achievements.

Robin felt as though they were moving chess pieces on a board that was vibrating in the preliminary tremors of an earthquake. It’s too late. You know, surely, that none of this matters anymore?

But when the talk was finished, Matthew said, “So we’re OK?”

“Yes,” she replied. “We’re fine.”

He had stood up, held out a hand and helped her up from her chair. She had forced a smile and then he had kissed her, hard, on the mouth, and begun to tug at the green dress. She heard the fabric around the zip tear and when she began to protest, he clamped his mouth on hers again.

She knew that she could stop him, she knew that he was waiting for her to stop him, that she was being tested in an ugly, underhand way, that he would deny what he was really doing, that he would claim to be the victim. She hated him for doing it this way, and part of her wanted to be the kind of woman who could have disengaged from her own revulsion and from her own reluctant flesh, but she had fought too long and too hard to regain possession of her own body to barter it in this way.

“No,” she said, pushing him away. “I don’t want to.”

He released her at once, as she had known he would, with an expression compounded of anger and triumph. Suddenly, she knew that she had not fooled him when they had had sex on their anniversary weekend, and paradoxically that made her feel tender towards him.

“I’m sorry,” she said. “I’m tired.”

“Yeah,” said Matthew. “So am I.”

And he had walked out of the room, leaving Robin with a chill down her back where the green dress had torn.

Where the hell was Strike? It was five past nine and she wanted company. She also wanted to know what had happened after he left the reception with Charlotte. Anything would be preferable to sitting here, thinking about Matthew.

As though the thought had summoned him, her phone rang.

“Sorry,” he said, before she could speak. “Suspicious package at bloody Green Park. I’ve been stuck on the Tube for twenty minutes and I’ve only just got reception. I’ll be there as quick as I can, but you might have to start without me.”

“Oh, God,” said Robin, closing her tired eyes.

“Sorry,” Strike repeated, “I’m on my way. Got something to tell you, actually. Funny thing happened last night—oh, hang on, we’re moving. See you shortly.”

He hung up, leaving Robin with the prospect of having to deal alone with the first effusions of Jasper Chiswell’s anger, and still grappling formless feelings of dread and misery that swirled around a dark, graceful woman who was sixteen years’ worth of knowledge and memories ahead of her when it came to Cormoran Strike, which, Robin told herself, shouldn’t matter, for God’s sake, haven’t you got enough problems without worrying about Strike’s love life, it’s nothing whatsoever to do with you…

She felt a sudden guilty prickle around her lips, where Strike’s missed kiss had landed outside the hospital. As though she could wash it away, she downed the dregs of her coffee, got up and left the café for the broad, straight street, which comprised two symmetrical lines of identical nineteenth-century houses.

She walked briskly, not because she was in any hurry to bear the brunt of Chiswell’s anger and disappointment, but because activity helped dispel her uncomfortable thoughts.

Arriving outside Chiswell’s house precisely on time, she lingered for a few hopeful seconds beside the glossy black front door, just in case Strike were to appear at the last moment. He didn’t. Robin therefore steadied herself, walked up the three clean white steps from the pavement and knocked on the front door, which was on the latch and opened a few inches. A man’s muffled voice shouted something that might have been “come in.”

Robin passed into a small, dingy hall dominated by vertiginous stairs. The olive-green wallpaper was drab and peeling in places. Leaving the front door as she had found it, she called out:

“Minister?”

He didn’t answer. Robin knocked gently on the door to the right, and opened it.

Time froze. The scene seemed to fold in upon her, crashing through her retinas into a mind unprepared for it, and shock kept her standing in the doorway, her hand still on the handle and her mouth slightly open, trying to comprehend what she was seeing.

A man was sitting in a Queen Anne chair, his legs splayed, his arms dangling, and he seemed to have a shiny gray turnip for a head, in which a carved mouth gaped, but no eyes.

Then Robin’s struggling comprehension grasped the fact that it was not a turnip, but a human head shrink-wrapped in a clear plastic bag, into which a tube ran from a large canister. The man looked as though he had suffocated. His left foot lay sideways on the rug, revealing a small hole in the sole, his thick fingers dangled, almost touching the carpet, and there was a stain at his groin where his bladder had emptied.

And next she understood that it was Chiswell himself who sat in the chair, and that his thick mass of gray hair was pressed flat against his face in the vacuum created by the bag, and that the gaping mouth had sucked the plastic into itself, which was why it gaped so darkly.
