Calm waters are often deceptive―and dangerous. Ramona Smith went missing, presumed murdered twenty-one years ago; her body was never recovered. Gerald Lace, accused, tried, and acquitted of the crime, took his own life shortly thereafter in the lovely-but-lethal waters along the Crooked Shore. In his suicide note, he blamed the police for wrongfully arresting him and ruining his life. On the twentieth anniversary of his father's suicide, Darren Lace has drowned himself in the very same spot. His death reopens the original investigation for cold case detective DCI Hannah Scarlett. Desperate to finally find answers, Hannah and her team chase leads as meandering as the shoreline. As the body count rises, old scores threaten to consume those dearest to Hannah. Will she be able to unwind both mysteries before her loved ones become collateral damage?
