No, the shock of what she had discovered in the receiving line had not rendered her surroundings blurred. It had instead affected her perception of both sound and time. At one point, she knew that Matthew had urged her to eat, but it did not register with her until after her full plate had been removed by a solicitous waiter, because everything said to her had to permeate the thick walls that had closed in on her in the aftermath of Matthew’s admission of perfidy. Within the invisible cell that separated her entirely from everyone else in the room, adrenaline thundered through her, urging her again and again to stand up and walk out.

If Strike had not arrived today, she might never have known that he wanted her back, and that she might be spared the shame, the anger, the humiliation, the hurt with which she had been racked since that awful night when he had sacked her. Matthew had sought to deny her the thing that might save her, the thing for which she had cried in the small hours of the night when everybody else was asleep: the restoration of her self-respect, of the job that had meant everything to her, of the friendship she had not known was one of the prizes of her life until it was torn away from her. Matthew had lied and kept lying. He had smiled and laughed as she dragged herself through the days before the wedding trying to pretend that she was happy that she had lost a life she had loved. Had she fooled him? Did he believe that she was truly glad her life with Strike was over? If he did, she had married a man who did not know her at all, and if he didn’t…

The puddings were cleared away and Robin had to fake a smile for the concerned waiter who this time asked whether he could bring her something else, as this was the third course that she had left uneaten.

“I don’t suppose you’ve got a loaded gun?” Robin asked him.

Fooled by her serious manner, he smiled, then looked confused.

“It doesn’t matter,” she said. “Never mind.”

“For Christ’s sake, Robin,” Matthew said, and she knew, with a throb of fury and pleasure, that he was panicking, scared of what she would do, scared of what was going to happen next.

Coffee was arriving in sleek silver pots. Robin watched the waiters pouring, saw the little trays of petits fours placed upon the tables. She saw Sarah Shadlock in a tight turquoise sleeveless dress, hurrying across the room to the bathroom ahead of the speeches, watched heavily pregnant Katie following her in her flat shoes, swollen and tired, her enormous belly to the fore, and, again, Robin’s eyes returned to Strike’s back. He was scoffing petits fours and talking to Stephen. She was glad she had put him beside Stephen. She had always thought they would get on.

Then came the call for quiet, followed by rustling, fidgeting and a mass scraping of chairs as all those who had their backs to the top table dragged themselves around to watch the speakers. Robin’s eyes met Strike’s. She could not read his expression. He didn’t look away from her until her father stood up, straightened his glasses and began to speak.

Strike was longing to lie down or, failing that, to get back into the car with Shanker, where he could at least recline the seat. He had had barely two hours’ slumber in the past forty-eight, and a mixture of heavy-duty painkillers and what was now four pints was rendering him so sleepy that he kept dozing off against the hand supporting his head, jerking back awake as his temple slid off his knuckles.

He had never asked Robin what either of her parents did for a living. If Michael Ellacott alluded to his profession at any point during his speech, Strike missed it. He was a mild-looking man, almost professorial, with his horn-rimmed glasses. The children had all got his height, but only Martin had inherited his dark hair and hazel eyes.

The speech had been written, or perhaps rewritten, when Robin was jobless. Michael dwelled with patent love and appreciation on Robin’s personal qualities, on her intelligence, her resilience, her generosity and her kindness. He had to stop and clear his throat when he started to speak of his pride in his only daughter, but there was a blank where her achievements ought to have been, an empty space for what she had actually done, or lived through. Of course, some of the things that Robin had survived were unfit to be spoken in this giant humidor of a room, or heard by these feathered and buttonholed guests, but the fact of her survival was, for Strike, the highest proof of those qualities and to him it seemed, sleep-befuddled though he was, that an acknowledgment ought to have been made.

Nobody else seemed to think so. He even detected a faint relief in the crowd as Michael drew to a conclusion without alluding to knives or scars, gorilla masks or balaclavas.

The time had come for the bridegroom to speak. Matthew got to his feet amid enthusiastic applause, but Robin’s hands remained in her lap as she stared at the window opposite, where the sun now hung low in the cloudless sky, casting long dark shadows over the lawn.

Somewhere in the room, a bee was buzzing. Far less concerned about offending Matthew than he had been about Michael, Strike adjusted his position in his chair, folding his arms and closing his eyes. For a minute or so, he listened as Matthew told how he and Robin had known each other since childhood, but only in their sixth form had he noticed how very good-looking the little girl who had once beaten him in the egg-and-spoon race had become…

“Cormoran!”

He jerked awake suddenly and, judging by the wet patch on his chest, knew that he had been drooling. Blearily he looked around at Stephen, who had elbowed him.

“You were snoring,” Stephen muttered.

Before he could reply the room broke into applause again. Matthew was sitting down, unsmiling.

Surely it had to be nearly over… but no, Matthew’s best man was getting to his feet. Now that he was awake again, Strike had become aware just how full his bladder was. He hoped to Christ this bloke would speak fast.

“Matt and I first met on the rugby pitch,” he said and a table towards the rear of the room broke into drunken cheers.

“Upstairs,” said Robin. “Now.”

They were the first words she had spoken to her husband since they had sat down at the top table. The applause for the best man’s speech had barely died away. Strike was standing, but she could tell that he was only heading for the bathroom because she saw him stop a waiter and ask directions. In any case, she knew, now, that he wanted her back, and was convinced that he would stay long enough to hear her agreement. The look they had exchanged during the starters had told her as much.

“They’ll be bringing in the band in half an hour,” said Matthew. “We’re s’posed to—”

But Robin walked off towards the door, taking with her the invisible isolation cell that had kept her cold and tearless through her father’s speech, through Matthew’s nervous utterings, through the tedium of the familiar old anecdotes from the rugby club regurgitated by the best man. She had the vague impression that her mother tried to waylay her as she plowed through the guests, but paid no attention. She had sat obediently through the meal and the speeches. The universe owed her an interlude of privacy and freedom.

Up the staircase she marched, her skirt held out of the way of her cheap shoes, and off along a plush carpeted corridor, unsure where she was going, with Matthew’s footsteps hurrying behind her.

“Excuse me,” she said to a waistcoated teenager who was wheeling a linen basket out of a cupboard, “where’s the bridal suite?”
