Sandy didn’t know how to answer that. He wanted to say that murder was important even if the victims didn’t belong to the islands. And that the murder of a ten-year-old child was important even if it happened years ago. Because he was starting to think that Peerie Lizzie had been murdered. Perhaps by her adoptive mother. And that both the Geldards had been happy to blame Sarah Malcolmson and see her move away. Then there would be nothing to remind them of the girl, and of the man’s sexual violence. They could continue to convince themselves that they were good people, and to hold their grand parties. Except that the child had come back to haunt them, even if she only appeared in their dreams, and eventually they’d had to move away too.

George was looking at Sandy and was expecting a response. The place was so quiet that they had been able to hear Grusche’s spinning wheel in the next room, the rhythm as soothing as a lullaby.

‘I just wanted to understand,’ Sandy said at last. ‘The story as we’d been told it just didn’t make sense.’ He paused. ‘Did Eleanor know the truth about Peerie Lizzie? Did Lowrie tell her the full background?’ Because why wouldn’t he? Lowrie was sophisticated and he lived in London. He wouldn’t understand why George would feel awkward about the true story of the dead child being made public. He would probably have lost the Shetland islanders’ habit of restraint and discretion. And it would make a great programme for Eleanor. A piece of detective work going back over time. Sandy could see that she would be excited.

‘I don’t think he would have told her about it,’

George said. ‘He’d grown up with thinking of it as something to keep in the family.’

But Lowrie might well have told his new wife. She was a family member too, an academic full of curiosity about unusual places and the people who lived in them. Perhaps Caroline had passed on the story to her friend. A gift. Something to cheer Eleanor up when she was depressed. Not realizing that it was any kind of secret.

The hum of the spinning had stopped. Sandy realized that if they had been able to hear the wheel, Grusche had probably heard every word of the conversation. She appeared now at the door, big and angular. She was wearing wide linen trousers and a loose fisherman’s smock. She ignored Sandy.

‘I’m going to phone Lowrie,’ she said. ‘Offer them a lift back from the boat club. In this fog I don’t think it’s safe for them to be walking back along the cliffs.’
