He sat them in the living room and went to the tiny kitchen to make coffee. There was a packet of biscuits at the back of the cupboard and he ripped it open and tipped them onto a plate. Chocolate digestives, Cassie’s favourites. He pulled a can of lager from the fridge for Sandy. He heard the murmur of conversation, but made no attempt to listen. The flash of curiosity he’d felt earlier that day about the Jerry Markham murder had long gone. He wondered why he’d bothered to get involved, to walk down the hill to the Ravenswick Hotel to talk to Peter and Maria.

When he carried in the tray, Willow was still standing at the window, looking over the Sound to Bressay. She took the mug that he handed her and sat, straight-backed, on the floor. Sandy pulled open the beer and took a handful of biscuits.

‘So what have we got?’ Willow said. She looked at them, and Perez thought they were an odd team for her to be lumbered with. It didn’t seem fair when it was her first major case. An emotional cripple who was likely to burst into tears or lash out at any opportunity, and a young Whalsayman who hadn’t really had the chance to grow up. Suddenly he felt sorry for her and made an effort to become engaged.

‘Did you hear that Markham left Shetland under a bit of a cloud?’ Perez said. He described what he knew of Jerry’s relationship with Evie Watt.

‘I’ve seen her about,’ Sandy said. ‘She didn’t go into bars much. You’d have her down as a quiet, studious sort of girl. Her father’s always going on about the old ways in his column, and she seemed kind of old-fashioned to me too. Religious.’

‘So she’s not one for partying then?’ Perez asked. Sandy liked girls who were up for a party.

‘No,’ Sandy said. ‘Not at all.’

‘But she fell for Jerry Markham.’ Willow looked up. ‘And was too naive to stop herself getting pregnant. Or perhaps that was her strategy. She thought it would be a way of holding on to him, the glamorous young journalist. Only he ran away.’

‘She lost the baby soon after,’ Perez said. ‘It looks as if she’s graduated and is working in Shetland. It might be worth tracking her down. She’d provide an insight into the man, even if she’s an unlikely suspect.’

‘Will you do that, Jimmy? She’s more likely to talk to you than to an outsider.’
