DCI Hannah Scarlett is an acknowledged expert in solving cold cases and is investigating the disappearance of a young woman from Bowness more than twenty years ago.

Now the case comes back into the public eye as the result of a shocking tragedy on the Crooked Shore, on the south coast of the Lake District.
Tensions mount in the summer heat as a ruthless killer who has already got away with one murder, plans further appalling crimes. Scarlett finds herself racing against the clock as she strives to solve the case.
