On a hot summer night, a watchful neighbor locks eyes with an intruder and unwittingly alerts the police to a vicious crime scene next door: a lavish master bedroom where a man lies dead. His wife is bleeding out onto the hardwood floor, clinging to life.

The victim, Adam Grant, was a well-known San Francisco prosecutor—a man whose connection to Homicide detective Valerie Hart brings her face-to-face with a life she’s long since left behind. Adam’s career made him an easy target, and forensic evidence points towards an ex-con he put behind bars years ago. But while Adam’s wife and daughter grapple with their tragic loss, Valerie uncovers devastating clues that point in a more ominous direction. Lurking in the shadows of the Grants’ pristine life is a mysterious blonde who holds the key to a dangerous past.

As Valerie struggles to forge a new path for herself, the investigation forces her to confront the question: can we ever really leave our pasts behind?
