Dark water - Caro Ramsay

A bitterly cold February in Glasgow. Hanging from a rope in the attic of a deserted tenement is the body of a criminal believed to have been hiding out on the Costa del Sol these last ten years. His face has been hideously disfigured.

Investigating officers DI Anderson and DS Costello believe the dead man to be a suspect in a decade-old case: the rape and attempted murder of a young student by two men. And there are other, similar cases on file.

But what has happened to the dead man's accomplice, 'Mr Click'?

And with the discovery of another young woman who has been brutally attacked, detectives Anderson and Costello realize this terrifying psychopath has started working once more. They must use every trick in the book to stop him. For Mr Click has developed a taste for his bloodthirsty trade. And to satisfy his lust he will strike again and again . . .
