Getting inside the mind of a killer isn't for the faint of heart....

A cold case and a series of drownings present forensic psychologist Alice Quentin with a terrifying mystery in an audiobook perfect for fans of Nicci French.

Jude Shelley, the daughter of a prominent cabinet minister, was assaulted and left for dead in the river Thames. Her attacker was never caught. A year later forensic psychologist Alice Quentin is asked to reexamine the case.

Then another body is found: an elderly priest, washed up at Westminster Pier. An ancient glass bead is tied to his wrist. Alice is certain that the Shelleys are hiding something - and that there will be more victims unless she can persuade them to share what they know.

The Thames has always been a site of violent sacrifice. And Alice is about to learn that some people still believe in its power.
