“About a year ago,” she said. “ Charlie was home on leave and I bumped into him in the Castle. It was good to have someone to talk to, flattering, I suppose, to have him so attentive. Towards the end of the marriage David had hardly noticed me. I told Charlie that I’d left David and that the boys and I were staying at Mum and Dad’s. But that’s all. I didn’t give him any encouragement. He walked me home and gave me a good-night kiss, but I didn’t mean anything by it. I was just pleased we were friends again.”

The heater was beginning to clear the ice from the windscreen and they could see the bulk of the Tower in the moonlight.

“What happened then?”

“Charlie left the army,” she said. “ It was awful. Like a nightmare. He wrote to his father to tell him and Fred Elliot turned up at our house accusing me of leading him on. “You’ve broken his heart once,” he said. “Now you’re meaning to do it again.” His wife had recently died and everything seemed to upset him. I didn’t know what to say or do. I wrote to Charlie telling him there was no point coming home, that I hadn’t changed my mind, but it didn’t do any good.”

“Did you persuade your father to give him a job?” Ramsay asked.

“No,” she said quickly. “ I didn’t want to have anything to do with him. My father thought that if he offered Charlie a job, there would be a reconciliation between the families. You don’t understand what it’s like in a place like this. The village was split in two, with half supporting me and half supporting Charlie. My father’s idea was to bring everyone together again.”

“But it didn’t work?”

“It would have done,” she said, “if Charlie hadn’t been such a bloody fool.” She began to cry. “ He’s worn me out. I don’t know if I can stand it any longer. I think he’s mad.”

“What does he do?” Ramsay asked.
