Ronald answered immediately. ‘She came into Shetland on holiday. She’s always been interested in the traditional crafts and she came to Whalsay to talk to Evelyn about the island knitting. It has its own unique pattern, apparently, and Evelyn’s a kind of expert. We met in the Pier House Hotel one night and kept in touch. She came to visit a few times . . . Maybe she fell in love with the place and not the man.’

Sandy had described Ronald as intelligent. For the first time Perez caught a glimpse of that. The man turned away suddenly and put his head in his hands. Perez and Sandy saw themselves out.

Chapter Eight

Sandy felt shattered. He’d always prided himself on being able to manage without much sleep. At Up Helly Aa he’d keep going for two or three days without getting to his bed, fuelled by the drink, the dancing and the company. He supposed this tiredness was to do with the shock. He’d never much understood the response of bereaved relatives when he’d come across them at work. He’d known he should be sympathetic, but their slow blankness and dull exhausted eyes had irritated him. He’d wanted to shake them. Maybe in the future he’d be less impatient. It had been such a relief when Jimmy Perez had arrived. Sandy had watched the ferry cross from Laxo with a sort of desperation, willing it to put on a bit of speed, knowing it was pathetic to want his boss to take things over, but not being able to help himself.

Now he was grateful that Perez had been so gentle with Ronald. Sandy had always got on well with Ronald, even though they were different. Sandy had never been one for schoolwork. He considered Ronald to be his best friend; when he finally took the plunge and decided to get married, he’d ask Ronald to be his best man. Jackie and Evelyn had never been friends. There’d always been the grit of envy and competition, and while Joseph and Andrew had been more civilized, Sandy had sensed a tension there too. Perhaps he and Ronald had become so close partly because their parents disapproved.

Perez hadn’t said anything after they’d left the Clouston house, except that he’d wished he’d thought to bring his wellies because the grass was so wet. He could go half an hour at a time without saying a word, and that really spooked Sandy. He liked chat, even as background noise, always had the radio or the telly on if he was on his own in his flat.

They were back standing by the car. ‘Where now?’ he asked, thinking if he didn’t move them on they could be here all day with Perez staring out towards the shore.

‘I don’t know about you, but I’m starving. Anywhere we could get a decent breakfast?’
