Hattie didn’t think Paul would have allowed her to set up the project if he’d been supervising from the start. But he’d only joined the department the year before. She remembered the meeting at which he’d been introduced to her and Sophie. ‘You’ll have heard of Paul Berglund,’ the head of department said. ‘You couldn’t wish for a better supervisor.’ Paul had shaken Hattie’s hand, said how pleased he was to be working with her and given no sign that they’d met before. His hand had been cold and dry; hers was sweaty. She’d muttered something about feeling unwell, fled the office and thrown up in the nearest ladies’ toilet. Perhaps he expected her to dump the project, find another subject for her PhD.

But she hadn’t left – the dig on Whalsay had been her idea from the start – and she had made sure that he had no excuse for excluding her. Now the merchant’s house mattered more to her than escaping from him. Her record-keeping was impressive and though she wasn’t as physically strong as Sophie, her fieldwork was deft and thorough. Whenever she was in Paul’s presence she felt tense. She watched him, always aware of the space he took up, of his position in the room.

‘Paul Berglund was in the bar after you left,’ Sophie said. They’d left the Bod and were on their way to Lindby. They couldn’t see much beyond the field on each side of the track. Sheep were darker shades in the mist.

‘Oh.’ Hattie tried to sound unbothered. She didn’t want to hear about him.

‘Yeah, he was drinking whisky. I’ve never seen him pissed before. Not that pissed.’

I have, Hattie thought, and shivered inside her fleece. ‘Anything else happen after I’d gone?’ She wanted to move the discussion away from Berglund.

‘Not really. I was chatting to Sandy, but he left before I did. He had to get home to his mammy. I mean, what is he like? He still acts like a fourteen-year-old.’ She shifted the straps of the rucksack on her shoulders. ‘I do see him as a bit of a challenge, though. I’m sure he gets up to all sorts of mischief in Lerwick. It would be fun to see if I can get him to misbehave here, on his mother’s doorstep.’

Hattie didn’t know what to say about that. She supposed Sophie could look after herself, but in her opinion all games around sex were dangerous. She would be quite pleased though if Sophie and Sandy hooked up with each other for a while.
