Homicide detective Tracy Crosswhite has returned to the police force after the sensational retrial of her sister’s killer. Still scarred from that ordeal, Tracy is pulled into an investigation that threatens to end her career, if not her life. A serial killer known as the Cowboy is killing young women in cheap motels in North Seattle.

Detective Tracy Crosswhite has a skill, and a soft spot, for tackling unsolved crimes. Having lost her own sister to murder at a young age, Tracy has dedicated her career to bringing justice and closure to the families and friends of victims of crime. So when Jenny, a former police academy classmate and protégé, asks Tracy to help solve a cold case that involves the suspicious suicide of a Native American high school girl forty years earlier, Tracy agrees. 

When a woman’s body is discovered submerged in a crab pot in the chilly waters of Puget Sound, Detective Tracy Crosswhite finds herself with a tough case to untangle. Before they can identify the killer, Tracy and her colleagues on the Seattle PD’s Violent Crimes Section must figure out who the victim is. Her autopsy, however, reveals she may have gone to great lengths to conceal her identity. So who was she running from?

While investigating the hit-and-run death of a young boy, Seattle homicide detective Tracy Crosswhite makes a startling discovery: the suspect is an active-duty serviceman at a local naval base. After a key piece of case evidence goes missing, he is cleared of charges in a military court. But Tracy knows she can't turn her back on this kind of injustice.

Called in to consult after a young woman disappears, Tracy Crosswhite has the uneasy feeling that this is no ordinary missing-persons case. When the body turns up in an abandoned well, Tracy’s suspicions are confirmed. Estranged from her family, the victim had balked at an arranged marriage and had planned to attend graduate school. But someone cut her dreams short. Solving the mystery behind the murder isn’t Tracy’s only challenge. The detective is keeping a secret of her own: she’s pregnant.
