A May Bank Holiday in the Peak District is ruined by the tragic drowning of an eight-year-old girl among crowds of visitors in the tourist hotspot of Dovedale. For Detective Constable Ben Cooper, a helpless witness to the tragedy, the incident is not only traumatic, but leads him to become involved in the tangled lives of the Neilds, the dead girl's family.
As he gets to know them, Cooper begins to suspect that one of them is harbouring a secret -- a secret that the whole family might be willing to cover up.
Meanwhile, Detective Sergeant Diane Fry has a journey of her own to make -- a journey back to her roots. As she finds herself drawn into an investigation of her own among the inner city streets of Birmingham, Fry realises there is only one person she can rely on to provide the help she needs.
But that man is Ben Cooper, and he's back in Derbyshire, where his suspicions are leading him towards a shocking discovery on the banks of another Peak District river.
