Cassie Holmes has made a big change. She left sunny, warm Arizona and moved to Seattle to join three friends in a new endeavor. They started Miss Demeanor Private Detective Agency.
Her first case involves the disappearance of a 14-year-old girl, Cami Reynolds. Her mother is desperate to find the young girl and, even though she doesn't have much money, hires Cassie for the job. The new private detective finds a dark underworld lurks under the viaduct that runs along the Seattle Waterfront.
In the process of her search, she meets Jack Donovan, an undercover detective connected to a Seattle drug task force. He's six-foot-four and tries to be an imposing presence in her life. He appears to her as a homeless man, but she knows he's a cop and as the two compare notes, discover their cases crisscross paths.
