‘Ben, it’s Matt. Give me a call.’

The first one was a very short message, but it made Cooper frown. His brother didn’t usually call him unless it was really necessary. In fact, Matt was always scrupulous about not phoning his mobile because he knew he used it for work. He supposed he’d have to call back and see what was wrong. But there were two more messages to listen to yet.

‘Ben. Matt. Give me a call as soon as you can. It’s important.’

Now Cooper began to feel uneasy. He pressed the button for the third message.

‘Ben, please give me a call. It’s very important.’ Then a pause. ‘It’s about Mum.’

Turning her Peugeot from Castleton Road into Grosvenor Avenue, Diane Fry finally pulled up at the kerb outside number 12. The house had once been solid and prosperous, just one detached Victorian villa in a tree-lined street. Its front door nestled in mock porticos, and the bedsits on the top floor were reached only by hidden servants’ staircases. But now most of the occupants were students at the High Peak College campus on the west side of town.

Fry often found her flat depressing, especially when it was empty. But she’d found Wardlow depressing, too. The very ordinariness of the place had made the calls from the phone box near the church seem even more disturbing.

Though Wardlow had been bad enough, at least it wasn’t the real back of beyond, the area they called the Dark Peak. Up there was only desolation – bleak, empty moorlands with nothing to redeem them. She recalled the road sign she’d seen last time she was there: sheep for 7 miles. Seven miles. That was the distance all the way across Birmingham from Chelmsley Wood to Chad Valley, taking in a population of about a million people. But here in Derbyshire you could find seven miles of nothing. That just about summed it up.

She’d transferred from the West Midlands as an outsider, the new girl who had to prove herself. It had been a struggle at times, just as she’d expected. But she’d been focused, and she’d worked hard. And now she got a lot of respect, though it was mostly from people she despised.

Fry went to the window, thinking she’d heard a car in the street. But she could see no vehicles, not even pedestrians passing on their way home for the night. All she could see out there was Edendale.

No, wait. There was someone. Two figures parting on the corner, so close to the edge of her field of view that she had to press her forehead to the window pane to see them. A second later, one of the figures came into focus, walking towards the house. Angie.

Fry pulled away from the window before she was seen, and went into the kitchen. Two minutes later, she heard Angie’s key in the lock.

‘Hi, Sis.’

‘Hi. Had a good day?’

‘Sure.’

‘What have you been doing?’
