Her father was one of the most prolific serial killers in American history. Now Detective Margot Phalen must face a chilling possibility: what if it runs in the family?

As the daughter of notorious serial killer Ed Finch, Margot has spent decades escaping her past—changing her name, her appearance, and building walls no one can breach, except her partner, Detective Wes Fox, whose growing closeness threatens the isolation she depends on.

When her troubled brother shows up needing a place to stay, pressuring her to participate in a true crime documentary about their father, Margot’s carefully controlled world begins to unravel. Then she notices blood on her brother’s shoes just as a body is discovered in a dumpster near her home. Is she being paranoid, or might the monstrous legacy of her father be closer than she ever imagined?

A visit to her imprisoned father delivers another gut-punch: Ed had an accomplice who’s still free—and still hunting. As Margot investigates, she must confront the question that’s haunted her entire life: how much of her father’s darkness might she carry within herself?

Dark, gripping, and emotionally raw, this taut thriller will have you listening late into the night. Perfect for fans of Karin Slaughter, Tana French, and Lisa Gardner.
