Thrilled to spend the final hours of her spring break in the VIP room of an elite Manhattan club, fresh-faced Indiana college student Chelsea Hart remains behind when her girlfriends call it a night. The next morning, joggers find her body in East River Park, her blond hair brutally hacked off.
NYPD Detective Ellie Hatcher believes the group of privileged men last seen plying Chelsea with free-flowing alcohol most likely includes a murderer. But after building a tight case against a young hedge-fund manager, Ellie has her doubts, because Chelsea's slaying is eerily similar to three other murders from nearly a decade ago. Continuing the investigation long after the department brass is satisfied with their case, hard-headed Ellie plunges into a late-night party world of conspicuous wealth and hedonistic consumption to catch the real killer—unaware that a psychopath is watching her every move...and eager to kill again.
