Gabby Leggett left her Boston family with big dreams of making it as a model/actress in Hollywood. Two years later, she disappears from her apartment. Her family, former boyfriend, friends - and the police - have no idea where she is and no leads. Leggett''s mother hires Spenser to find her, with help of his former apprentice, Zebulon Sixkill, now an L.A. private eye. It''s soon clear that Spenser and Sixkill may be outgunned this time, and series favourites Chollo and Bobby Horse ride to the rescue.
