James Laidlaw looked strangely young without his spectacles. In the half light of the dunes Mary had mistaken him for Max and Ramsay could see how that was possible. James had lost all desire to fight. When they opened the back door of the police car for him, he got in without a word. He sat upright, a respectable figure. He was still wearing a suit. A policewoman who had taken Mary to her car was wrapping her in a rug, pouring tea from a flask.

Hunter was about to drive away when Ramsay tapped on the window. Hunter opened it with hostility, expecting another command or rebuke.

“Well done,” Ramsay said. “That was a good arrest.”

Chapter Twenty-Five

Ramsay would have liked to take Mary Raven to his cottage in Heppleburn to talk to her. He would have been more comfortable there, without interruptions and telephone calls. He could have made her coffee and waited until she was ready to talk. But he knew it would not do and the interview would have to take place in the police station in Otterbridge, with its institutional furniture and the knowledge that somewhere in the same building James Laidlaw was being questioned, too.

At first she refused to go with him.

“It’s my story,” she said. “I need a phone and a typewriter. No other bugger’s going to get the glory after all this work.”

“It will be your story,” he said, coaxing her with his attention and his gratitude. “ There’ll be no press release tonight. All the papers will know is that James Laidlaw has been arrested. They’ll be desperate to talk to you tomorrow. And, you know, I might be able to give you some useful information.”

So she allowed herself to be helped into the back of his car, complaining only when he drove past the Castle Hotel without stopping to buy her a drink. At the police station he left her for a while in the company of a policewoman, but she seemed not to mind and from the corridor he saw her scribbling intensely in her notebook. He went to talk to Hunter. Laidlaw, it seemed, had started talking as soon as the car left Brinkbonnie and nothing could stop him.

“He asked to write a statement,” Hunter said. “He’s doing that now. He refused to see a solicitor. We’ll have no problem with a conviction.”

So when Ramsay returned to begin his interview with Mary, he knew most of the details of the case. But he gave nothing away. He was diffident, unsure, so she thought he needed her. He let her believe that it was her story after all.
