Inside the house, he saw his mother through Perez’s eyes: little, round, short hair that she trimmed herself if she couldn’t get into Lerwick, dressed today in her best hand-knitted sweater because she was expecting guests. Enough energy to power Shetland Hydro. She’d already warmed the pot and made the tea and she was still talking. But she’s not a stupid woman, Sandy thought, and Perez will see that too. She got all that money out of the Arts Trust for the community theatre project last year and everyone says she’s the best chair the island forum has ever had.

There was a newborn lamb in a cardboard box next to the Rayburn. ‘An orphan,’ Evelyn said. ‘We’re hand-rearing her. No one else would bother, but Joseph’s a soft old thing.’

Now that the tea was brewing she turned back into the room. ‘What can I get you to eat? We’ve got some of our own bacon and Mima gave me a dozen eggs yesterday, so I have plenty to spare. Will that do you?’

Sandy found himself remembering the day his father had killed the pig. Because it was for the family’s own use there’d been no need to send it out to the abattoir, but it was a horrible job. The pig always made a dreadful noise before the throat was cut. He’d seemed to sense what was about to happen to him. Sandy had been on the island that day, but he’d not been a lot of use. He’d stood watching along with Anna. His father had been the strong one, finishing off the job with Ronald’s help, and Evelyn had caught the blood in a bowl.

‘It sounds brilliant, Mrs Wilson,’ Perez said. He’d made himself at home already. His shoes were left in the porch and he’d taken the chair by the table where Sandy’s father usually sat. She beamed, took down a heavy frying pan from the wall, opened the Rayburn hotplate.

‘Mrs Wilson, indeed! No one’s called me that in this house since that politician from the SNP came canvassing at the last election.’

It was warm in the kitchen and Sandy felt himself nodding off, heard the conversation between Perez and his mother as though from a long distance.

‘What time did you last see Mima?’ Perez asked.

‘About two o’clock. I called round to have a chat about the dig. The two lasses from the university were there. What nice wee girls they are, though I think that Hattie could do with a bit of feeding up. She’s a skinny little thing. All eyes and bone.’ She paused to take breath.
