The buildings at Voxter were darker shapes against the sky. Chickens stirred in the hen house as he passed. He stopped outside the house and looked in through the window. The light was still on in the kitchen. There was no sign of George in the chair, where Sandy had left him earlier in the evening, though a nearly empty bottle of whisky and a glass remained on the table. No sign of Grusche, either. Sandy thought if they had any sense they’d both be in their bed. Caroline had said she’d spoken to them when she’d phoned Voxter about the missing woman, but that might have been a while ago. Sandy wondered if George was outside helping in the search. He tapped on the window, but there was no response, so he walked round to the front door. He switched off his torch because there was light from the window and his eyes were accustomed to the dusk now. The door was unlocked and he went inside.

There was a rush of sound and a white figure appeared in front of him. It was Grusche in an old-fashioned cotton nightgown and a shawl wrapped around her shoulders. ‘Who is it? Lowrie, is that you?’ She sounded older than Sandy remembered, panicky and frail. He realized that if she’d come out of a lit bedroom, he would be just a shape to her.

‘It’s Sandy Wilson. The detective from Lerwick.’ ‘Sandy, what are you doing here at this hour of the morning? You scared me.’ She reached out for a switch and suddenly the room – a small scullery with space for boots and coats – was full of light.

He blinked. ‘Polly Gilmour is still missing. Jimmy Perez sent me here to see if she’d wandered this way.’

‘We’d have told you if she was here, Sandy. Of course we would. Caroline phoned earlier to say she was missing.’ She paused. ‘These have been terrible times. I’ll be glad when the English people go south again. They’ve brought nothing but trouble.’

Sandy thought that Caroline was English too, but perhaps Grusche already counted her as local.

‘Could I speak to George?’

She hesitated for a moment. ‘He’s asleep,’ she said. ‘He’d been drinking all evening and I sent him to bed.’ Her voice was bitter. Sandy decided you could never tell what went on between a man and his wife. The picture they showed to the world could be quite different from what went on in the home. It started with the wedding – all music and smiling, a kind of performance – and then unless you were lucky things started to crack. Maybe Grusche was so eager for Lowrie to move back to Shetland because George provided no companionship for her at all.
