The Lake District’s cold case specialist, DCI Hannah Scarlett, is determined to uncover the truth behind Bethany Friend’s apparent suicide six years ago, in the Serpent Pool. Why would Bethany, so afraid of water, drown herself? Hannah fears that her partner, bookseller Marc Amos, is keeping dark secrets, and holds the key to Bethany’s past. Hannah still carris a torch for Daniel Kind, who is researching Thomas De Quincey and the history of murder. Once Daniel and Hannah suspect connections between Bethany’s drowning and a current sequence of killings, death comes dangerously close to home.
