“I see.” Ramsay stood up and walked towards the window. The room was so stuffy that he felt he would fall asleep. He did not know what to make of the builder who stood before the gas fire with such confident certainty. “What time did Mrs. Parry leave here?”

“Quarter to eleven,” Henshaw said.

“Are you sure?”

“I looked at the clock,” Henshaw said. “ I knew it was late. I offered to drive her home, but she said she’d rather walk.”

“Did you go out after she went?”

“No,” Henshaw said shortly. “ I’ve told you. It was late. We went to bed.”

There was a silence. Ramsay felt he was getting nowhere with the builder. Henshaw would have an answer whatever question was asked. Ramsay felt tired and incompetent. Hunter, he thought, would have bullied something out of him.

Rosemary Henshaw let Ramsay out of the house. Her husband, unmoved, stayed in the living room and barely looked up to say goodbye. In contrast she was too friendly to the policeman, almost gushing: “ Do let us know if there’s anything we can do to help. Call at any time.”

Then he was gone. She watched him walk down the drive until the only sign of him was the sound of his shoes on the frosty gravel. She realised how cold she was and shut the door.

She was a plump woman, always had been. Built like a dairymaid, Colin had said when they first met. He was a city boy from the west end of Newcastle and he liked to think of her as a country girl, though there was nothing romantic about her childhood.

“We’ll live in the country one day,” he had said when they first moved into their flat in town. He had talked a lot about what he wanted in those days and she had thought he was just dreaming. Now, wanting things had become a habit and he seemed unable to stop.

After seeing Ramsay out, Rosemary Henshaw paused in the hall before an ornate gilt-framed mirror and absent-mindedly studied her reflection. She wanted to confront Colin about the policeman’s visit, but she had left the important things to him for so long that she did not know how to begin. He would accuse her of making a scene, as he did sometimes when she asked tentatively where he had been when he stayed out all night. She knew he had other women and had stopped asking. She did not want to cause a scene. She wanted to offer Colin her help, but even that seemed an impudent thing to do because he was so far above her in intelligence and understanding. She wanted, above all things, to know what was going on.
