‘It was only a bit of rough grazing and he was never a farmer.’

‘What does Ronald do for a living?’

‘He’s got a place on his father’s pelagic trawler. The Cassandra. She’s a beauty. Four years old now, but still state-of-the-art.’ It was what Perez had been expecting and fitted in with the image of the hard drinker who went out in the middle of the night shooting. Most of the Whalsay boats were family-owned. Fishing was a tough life and the men let off steam when they came ashore.

‘He was the brainy one at school,’ Sandy went on. ‘Not much good at anything practical, but OK at passing exams. Kind of dreamy, you know. He went off to university, but his father was taken ill and the place came up on the boat. He had to take it. You understand how it works. Maybe he was glad of the excuse to leave and he wouldn’t have got his degree anyway. That’s what my mother says.’

A bit of jealousy there, Perez thought. Or competition between the two cousins, Sandy’s mother and Ronald’s mother, comparing their sons. No one would ever have called Sandy brainy.

‘Is the wife a Shetlander?’

‘No, Anna’s English. They had their wedding here, though, a couple of years ago. All her folks came up for it. It was a grand do.’ Sandy’s eyelids drooped for a minute and he shook himself awake, stared out at the drizzle. Condensation ran down the inside of the windscreen.

Perez thought this was still a huge house for two people and one baby. He wondered where Ronald had met his Anna. There was a history of Shetland men going out to find their wives. During his brief spell at university perhaps. Perez had married an Englishwoman. Sarah, soft and gentle, pretty and fair. But he hadn’t had it in him to be the sort of husband she’d wanted. He’d always been too easily caught up in other folks’ problems. ‘I always come at the bottom of the pile,’ she’d said. ‘After work and your parents, sorting out the neighbour’s delinquent son and the plumber’s cat. You’re drained when you do find time for me. You’ve nothing left to give.’ At the time he’d thought she was talking that way because she’d just been through a miscarriage. Now he could see there was some truth in her words. He couldn’t keep his nose out of other people’s business. He told himself it was about being a good detective, but he’d have been curious even if work weren’t involved.

Sarah was happier now without him, married to a doctor and living in the Borders with him, her children and her dogs. And Perez had taken up with another Englishwoman, divorcee Fran Hunter. Sarah had always been needy. Fran, he thought, didn’t need him at all.
