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. Next to him, 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.
