For a while during the meal Eleanor wasn’t mentioned at all. Ian and George were drinking steadily, both intent, Polly thought, on getting drunk. All she knew of George was that he’d once been a lightkeeper. Lowrie had talked of growing up with the ritual of his father disappearing for four weeks out of eight. ‘The Lighthouse Board flew him out to Muckle Flugga in the helicopter and sometimes the weather was so wild that he couldn’t get home.’

‘That must have been tough,’ she’d said. She and Lowrie were both only children, and her father had doted on her. She’d looked forward to him coming home each day from the factory where he was a supervisor, the sound of his key in the door. She couldn’t imagine having grown up without him.

‘Not at all.’ Lowrie had laughed. ‘My mother spoilt me rotten. And it wasn’t so unusual then. Lots of kids’ parents were at sea or worked on the rigs. It was almost easier when he was away. He’s found it hard to adjust to life with more than two other people. If he seems a bit odd just now, that’s the reason for it.’

Polly wondered if George had developed the habit of heavy drinking when he worked on the rock. There’d surely be no drink allowed in the lighthouse, so perhaps he’d made up for it when he was at home and that had formed a ritual too. Lowrie’s parents seemed a strange couple to her. Grusche was cultured. She knew about books and films and talked about her weekly treat – a trip to the matinee movie at the Mareel arts centre in Lerwick. ‘It’s not all blockbusters from the US, you know. We get our share of art house too. I can’t wait until I’m a pensioner and then I’ll get a free cup of tea at the afternoon viewings.’ George seemed entirely absorbed by the work of the croft and had no interest in any life away from the islands. It had always been Grusche who’d come to visit Lowrie when he’d been at university, dragging him off to plays and art exhibitions, exhausting him with her energy. Polly could only remember seeing George once. He’d been there for Lowrie’s graduation, uncomfortable in an old suit that didn’t quite fit, while Grusche had been splendid in a dress that she’d made herself. And as soon as the ceremony was over George had taken them all to a pub and stood a round of drinks for the whole crowd. Her own parents had stood awkwardly beside her; it had been the first time they’d been in a bar for years.

It was Grusche who first brought up the subject of Eleanor’s murder. ‘You’re very lucky to have Jimmy Perez working on the case. He’s a good man. I knew his girlfriend, Fran. She was a fine painter.’ The table fell silent and everyone looked at her. She seemed not to notice, though, and began to clear the plates. Then she paused. ‘Of course Jimmy will understand what pain you’re going through. Fran was murdered too.’
