In this "riveting" thriller, "readers will find themselves wondering whose story to believe," the ex-wife seeking justice or the ex-cop hired to stop her. (Booklist) Claire Fontaine is convinced her ex-husband killed their teenage daughter years ago and believes he's capable of killing again. When she sees him move in with another woman, to play step-father for a girl the same age as the one she lost, Claire tries desperately to warn the new bride of the danger. But when the woman dismisses her admonishments, Claire takes matters into her own hands. Sloane Wilson left the LAPD to work as a "sin eater," a contractor for hire who specializes in cleaning up inconvenient situations―situations better handled outside the law. Like the ex-wife who stalks her former husband and makes threats to his new wife. As Sloane investigates, she uncovers a history of trauma that casts aspersions on Claire as well as Sloane's client. Soon the truth becomes increasingly muddled. But Sloane knows one thing for certain: sometimes the only way to prevent a crime is by committing one.

Finn, #1 New York Times bestselling author of The Woman in the Window "Beautifully, beautifully written and suspenseful from the chilling opening until the end." ―James Patterson, #1 New York Times bestselling author "Buelens will inevitably invite comparisons to Liane Moriarty and Gillian Flynn―a taut, gripping noir mystery that is as timely as it is ferocious." ―Lyndsay Faye, award-winning author of The Paragon Hotel
