The instant New York Times bestseller, for the first time in mass market: Worlds collide when an FBI agent investigates a string of grisly murders on Long Island and faces the impossible question: What happens when the primary suspect is your father?

FBI agent Nell Flynn hasn't been home in ten years. Nell and her father, Homicide Detective Martin Flynn, have never had much of a relationship. And Suffolk County will always be awash in memories of her mother, Marisol, who was murdered when Nell was just seven.

When Martin dies in a motorcycle accident, Nell returns to the house where she grew up so that she can spread her father's ashes and close his estate. At the behest of her father's partner, Detective Lee Davis, Nell becomes involved in an investigation into the murders of two young women in Suffolk County. The further Nell digs, the more likely it seems to her that her father should be the primse suspect--and that his friends on the police force are covering his tracks.

Plagued by doubts about her mother's murder, and her own role in exonerating her father in that case, Nell can't help but ask questions about who killed the two women and why. But she may not like the answers she finds--not just about those she loves, but about herself.
