The tension between his parents could be caused by anxieties about money. He preferred to think it was about that. Any other cause – sex: that one of them had fallen for someone else – was simply horrible. They were old and they were his parents; he couldn’t contemplate it. He wondered if he was overreacting. Perhaps the two deaths so close to home had made him jittery and caused him to blow trivial arguments out of proportion. Then he remembered his father yelling at his mother after Mima’s funeral. Joseph had never raised his voice to Evelyn throughout their marriage, even when he was exhausted after working all day for Duncan Hunter. Sandy wasn’t overreacting. Something was wrong between them.

Then came the difficult part. He forced himself to order his ideas and take the next logical step. If his parents had problems with money, was it possible that one of them had shot Mima for her house and her land? Not Joseph. He could tell how upset his father was. Besides, he’d been made a good offer for the house already and he’d turned it down. Evelyn then? Sandy had known all along that this was where the thinking would end up. Evelyn had never particularly got on with Mima. She could shoot well enough and there was a shotgun in Utra. But if the couple had no money problems, then there would be no real motive. That was why Sandy was lurking in Utra like a thief or a spy.

He knew where his mother kept the bank statements: in the drawer in the sideboard in the living room, where the lasses had put the silver coins before the man from the university had taken them away. It was locked, but the spare key was hanging from a hook in the larder along with all the others. Evelyn had always been the one to look after the family finances. Even when his father had worked for Hunter she’d sorted out the bills and the invoices and filled in Joseph’s tax returns. Sandy could remember her sitting at the table every month, going through the bank statements, frowning when she saw how little they had to live on until the next paycheque.

He found the key and unlocked the drawer. The statements were neatly clipped together in the blue file he remembered. He looked immediately at the balance and felt a wild relief when he saw it was in credit. He scanned back over the past twelve months. No problems. Little excess in the pot, but no debt. He wondered if Evelyn could have taken out a loan, but there was no sign of that and the paperwork would be in the drawer too. How could I have doubted her? he thought. How could I have even considered for a minute that she would be capable of murder?
