He walked across the field towards the dig, his coffee mug still in his hand, and paused as he always would now at the spot where he’d found Mima’s body. Would it be such a terrible thing to give up his work in Lerwick and take over Setter? He was good with beasts and it would make his father awful happy. If he sold his flat he could bring some cash and some energy into the place, make a real go of it. But even as the thought came into his head, he knew it was impossible. He’d end up hating his family and the island. It was better to stay as he was and just come every now and again to visit.

By now he’d reached the practice trench where his mother had found the skull. He peered inside. What was he expecting? More bones, growing out of the ground, an elbow maybe, bent like a huge potato tuber? Or a row of toes? Of course there was nothing, except the earth scraped flat by his mother’s trowel.

He sauntered on to the deeper trench where the medieval house had stood, where the silver coins had lain hidden for hundreds of years. He knew he was putting off his return to Utra. He couldn’t face the stoic good cheer of his father or his mother’s restless energy. He had a hazy recollection of television documentaries. What if he found a whole heap of coins, gold and silver, jewellery maybe? He had a picture of a pile of rubies and emeralds glinting in the morning sunshine. Wo uldn’t that be considered treasure trove? Wouldn’t it make enough money so his parents could take a holiday, so they wouldn’t have to work quite so hard to keep up with the Cloustons and the other fishing families? He checked himself: he was making up fairy tales in his head again. As a child he’d been told stories of the trows who hoarded shiny, glittering objects, but it would never happen in real life.

But as he approached the rectangular hole in the ground, for a moment it seemed as if the childish fantasy was being played out in real life. The sunlight was reflected from an object within it, a dull gleam that might be buried treasure.
