Thirty-five-year-old Rae Sullivan owns a thriving home décor shop in the San Francisco Bay area, near majestic Mt. Tamalpais (to locals, The Sleeping Lady). But when her business partner, Thalia, confides that she has a lover in France, Rae's comfortable life starts to unravel. Soon, an anonymous note-writer threatens to reveal the affair, and Thalia--who, unswayed by Rae's warnings, insists on confronting the blackmailer--turns up dead in Golden Gate Park. The police, convinced the crime was a random mugging, are dismissive of Rae's story of blackmail. Then a scandal from Rae's past job comes to light, and the police start to eye her as a suspect. To clear her reputation and ensure justice for Thalia, Rae decides it's up to her to unmask the murderer--despite her husband's objections. Rae's sleuthing leads her to France, where she enlists the help of Thalia's handsome half brother. As they collaborate to catch the killer, sparks fly between them, and Rae has to contend with these newly aroused feelings--even as she strives to outmaneuver a cold-blooded murderer who wants to silence her.
