On the way south Perez thought about Angela. He hadn’t realized the reputation she’d gained on the island. His father would call her a scarlet woman. Perez had known her as a celebrity, someone the place was proud to acknowledge as a resident. This was another woman he couldn’t get a fix on. Sarah Fowler and Angela Moore: two unfathomable women. He was losing his grip. He thought maybe he should speak to Angela’s family. They had no record of her mother’s whereabouts, but there was a father, who’d brought her up. He lived on his own in Wales. The local police had informed him of Angela’s death but Perez had no information about how he’d taken it. He wished he could have been there when the constable had knocked at the father’s door, but what would he have asked? Was your daughter always a sexual predator? He made a mental note to track down the Welsh officer who’d notified Angela’s father of her murder.

Ben Catchpole was waiting for Perez outside the hall. Perez saw the tall figure as he walked from the road. It was playtime in the school and the children were playing in the yard; a couple of the girls were swinging a long rope for the others to jump over. Perez waved to the individuals that he recognized. They giggled and waved back.

Inside the hall, he set the tape recorder on the table and asked if Ben had any objections. The man shook his head. Then Perez realized he was terrified, so scared that he was almost frozen and could hardly speak.

‘How long have you been working at the North Light?’ Factual, unthreatening.

‘This is my third season.’

‘Isn’t that unusual?’ In Perez’s experience most of the assistant wardens just stayed for one year. He looked at Ben’s statement. Although he looked so young he was nearly thirty. ‘I mean, it’s only seasonal employment. Aren’t you looking for something more permanent?

‘You think I should be settling down, Inspector?’

Perez didn’t answer and after a pause Ben continued: ‘I grew up in a weird kind of family. I mean it didn’t seem weird when I was growing up, but it was different from other kids’. My mum was one of the Greenham women and she couldn’t settle to domesticity when she left the Common. There was always a battle to fight, strangers coming to stay, discussions into the night about politics and justice and the environment. I suppose for me communal living seems kind of normal.’

‘I’ve checked your criminal record. You were found guilty of criminal damage. Lucky not to get a custodial sentence, according to the notes. That was here on Shetland?’
