The Seaforth Estate had been baking in the midday sun when Strike visited it the following day. The houses here were the oldest of the island’s military accommodation, white-painted and a little shabby. He had chosen to visit while Laing, who had successfully eluded his charge of rape, was busy at work. When he rang the doorbell, he heard only a baby’s distant cries.

“We think she’s agoraphobic,” confided a gossipy female neighbor who had rushed outside to share her views. “There’s something a bit off there. She’s really shy.”

“What about her husband?” asked Strike.

“Donnie? Oh, he’s the life and soul, Donnie,” said the neighbor brightly. “You should hear him imitating Corporal Oakley! Oh, it’s spot on. So funny.”

There were rules, many of them, about entering another soldier’s house without his express permission. Strike pounded on the door, but there was no answer. He could still hear the baby crying. He moved around to the rear of the house. The curtains were all closed. He knocked on the back door. Nothing.

His only justification, if he had to defend his actions, would be the sound of that baby crying. It might not be considered sufficient reason for forcing entry without a warrant. Strike mistrusted anyone who was overreliant on instinct or intuition, but he was convinced that there was something wrong. He possessed a finely honed sense for the strange and the wicked. He had seen things all through his childhood that other people preferred to imagine happened only in films.

The door buckled and gave the second time he shouldered it. The kitchen smelled bad. Nobody had emptied the bin for days. He moved into the house.

“Mrs. Laing?”

Nobody answered. The baby’s feeble cries were coming from the upper floor. He climbed the stairs, calling out as he went.

The door to the main bedroom stood open. The room was in semidarkness. It smelled horrible.

“Mrs. Laing?”

She was naked, tied by one wrist to the headboard, partially covered by a heavily bloodstained sheet. The baby lay beside her on the mattress, wearing only a nappy. Strike could see that it looked shrunken, unhealthy.

As he bounded across the room to free her, his other hand already scrambling for the mobile to call an ambulance, she spoke in a cracked voice:

“No… go away… get out…”

Strike had rarely seen terror like it. In his inhumanity, her husband had come to seem almost supernatural. Even as Strike worked to release her wrist, which was bloody and swollen, she begged him to leave her there. Laing had told her that he would kill her if the baby was not happier when he returned. She did not seem able to conceive of a future where Laing was not omnipotent.

Donald Laing had been sentenced to sixteen years’ imprisonment for what he had done to his wife, and Strike’s evidence had put him away. To the last, Laing had denied everything, saying that his wife had tied herself up, that she liked it, that she was kinky that way, that she had neglected the baby, that she had tried to frame him, that it was all a put-up job.
