Fran saw this was at the root of the girl’s misery. It had affected her more than Angela’s death and her father’s grief; she felt abandoned. She had been desperate to leave the island to find out why her older man was refusing to respond to her. When she was mooning in her bedroom, listening to depressing music and watching endless television, it was the man she was thinking of, not the violence of her stepmother’s death.

‘Angela knew,’ Poppy said. ‘She knew that Des hadn’t been in touch. She laughed about it: “What would a grown man see in you?” She didn’t do it when Dad was around, but when we were on our own she’d pick away at me: “Heard anything from the boyfriend yet? Still no news?” I think it drove me crazy. In the flat with the wind howling outside. Nobody to talk to. I dreamed of killing her. When it actually happened I could almost believe I’d done it, I’d wanted it so much. I was drunk and I couldn’t remember much about the night of your party. Perhaps it was me after all.’

She turned so Fran saw her face and realized how scared she was. She wanted a reassurance Fran wasn’t able to give. Fran tucked her arm around Poppy’s and they walked together into the shop. ‘Chocolate,’ Fran said in the no-nonsense tone she used to Cassie when she woke with nightmares. ‘That’s what you need.’

They sat on the bench outside the shop to eat the sweets they’d bought. ‘Do you have any idea who might have killed Angela?’ Fran asked. She couldn’t help herself. ‘You were there all day, every day.’

Poppy shook her head. ‘She was in a weird mood all week,’ she said. ‘I mean, even weirder than usual. Something was freaking her out. She treated them all like she did me – poking and prying. It could have been any of them.’

Later Fran and Mary distracted Poppy with long games of Scrabble and Cluedo. They sat at the kitchen table and at last could hear the sound of sheep and herring gulls over the wind. James was at the Haven supervising the return of the Good Shepherd into the water. In the croft, Poppy shrank back into herself and there were long periods of silence. She could have been sulking. It seemed to Fran that the girl switched from a woman to a child and back again in seconds. She wondered how any parent could deal with these mood changes. She could see why Poppy’s mother had needed a break.

At four o’clock Fran offered to drive Poppy back to the North Light. She hoped she might catch up with Perez there, even for a few minutes, and thought she was as star-struck about him as the girl was with her unsuitable boyfriend. But Poppy said she would walk.
