Three novels featuring Derbyshire police detectives, DC Ben Cooper and DS Diane Fry from award-winning crime writer Stephen Booth.BLACK DOG - The long, hot Peak District summer came to an end when they found Laura Vernon's body. But for local policeman Ben Cooper the work has just begun. His community is hiding a young girl's killer and a past as dark as the Derbyshire night.

But the past has a way of influencing the present and before either knows it, a long-cold trail in the dead of winter has grown dangerously hot ...
