They’d reached the steps that led through the terraced garden. David paused for a moment, not to catch his breath – he was obviously very fit – but to remember. ‘I’ve never told anyone else that story.’ Another pause. ‘But then nobody has ever asked.’ They stopped at the front door. ‘What will happen now?’

‘Willow has already contacted the funeral director in Lerwick,’ Perez said. ‘Charles will go south for post-mortem. You met James Grieve, the pathologist. He’s great at what he does.’ He hesitated. ‘Very respectful.’

‘What do think killed him?’ It came out as a strangled cry of pain.

‘Dr Grieve will help us to know that.’ Perez remembered a conversation with the pathologist, late one night. Another case. They’d had dinner together and shared a bottle of wine. My patients aren’t the dead, Jimmy, but the living relatives. My responsibility is to them. At least there was no mystery about what happened to Fran, he thought. I was there. He had a sudden flashback: the lightning glint of a knife in moonlight. A scream. He thought not knowing how she’d died would have been the worst kind of torture.

Sandy was waiting for them inside. ‘I found rooms for the other guests in a B&B in Yell and booked them onto the ferry. They left five minutes ago.’ His voice was almost a whisper, but David wouldn’t have heard if Sandy had shouted. He was lost in memories of his lover.

‘What should I do?’ David asked. It was as if he was a stranger in his own home. Perez thought the roles had reversed now. The police officers were in charge of the place and David was more like a guest. ‘I want to help.’

‘We’d be really glad of some coffee, if you’re up to making it.’

David looked grateful to have something specific to do and disappeared towards the kitchen. Perez sent Sandy to the beach to relieve Willow. Hillier’s death must be linked to Eleanor Longstaff’s, and he wanted to speak to the group at Sletts before news of the tragedy leaked out. But he knew better than to go without speaking to Willow first. The only time they’d really fallen out on an earlier case was when he followed his own line of investigation. And the previous evening he’d pushed his luck by talking to George without her permission. He stood by the front door and watched Sandy’s progress across the beach, then waited as Willow walked towards him. He saw her as if for the first time, the long, tangled hair and the easy stride, and thought she looked more like a Viking than most Shetlanders. He could imagine her rowing a longboat with the strength of a man. The thought made him smile and the image stayed with him until she reached him.
