There were still sheepskins on the bed. White ones and black ones, piled in profusion, more of them certainly than had been there when he’d spent the lazy afternoons here with Sarah. Perez saw them while he was still standing on the ladder. He reached in to set down the candle, so he could use both hands to climb into the loft. At the same time he saw the woman’s body lying, as if in abandon, on the rugs, and the blood that had turned the sheep’s wool pink, as if it had been dyed. He saw the small white feathers that covered the skin like flakes of snow.

Perez stood for a moment, so shocked by the scene in front of him that it was as if his hands were frozen to the ladder rungs. A draught caught the candle flame, made it flicker and then burn more brightly, and he saw the patterns of blood spatter on the wooden walls of the loft: at some point the killer had pierced an artery. This was quite a different murder. The first had been planned and calmly executed. This was wilder. If it had been committed by the same person, the killer was beginning to panic or to lose control.

Chapter Twenty-two

Sitting at the makeshift table in the ground floor of the Pund, Perez made phone calls. His voice was abrupt and urgent. The colleagues on the end of the line hardly recognized it. The Perez they knew was relaxed and softly spoken. He didn’t bark out orders or shout down their objections.

The first call was to Sandy. ‘Is Vicki Hewitt in from Aberdeen yet?’

‘Aye, she’s ready for the boat in the morning.’

‘I need you to charter a plane and get into Fair Isle now. Bring Vicki with you.’

‘You’ll not get a plane tonight.’ Sandy would have liked the drama of the emergency flight; Perez could tell that. He just didn’t see how it was possible. ‘It’s almost dark.’

‘There’s no wind to speak of and there’ll be a moon. We’ll light the airstrip. They’d do it for an ambulance flight.’

‘What’s the rush?’

‘There’s been another murder. I need the crime scene assessed by an expert before it gets contaminated. This doesn’t look to me like the same sort of killing. This victim’s been stabbed, but it’s not such a clean job. More wounds. More of a struggle, I’d say, though the scene’s been posed like the first time.’ Perez paused for breath. ‘And I want suspects properly interviewed. I can’t do that on my own. I need you both here tonight. Within an hour if possible.’
