Bree's new home is luxurious and private, with a fancy Beverly Hills address. What a shame it's not hers. Widowed, penniless, living in her car, and out of options, she's climbed the fence and crashed in the pool house. All she wants is a good night's sleep. But when Sophie, the absentee owner, finds her, she gets a whole lot more.

Sophie invites Bree back for a party. When it winds down, Bree can't resist sneaking upstairs to sleep in a real bed. But the next morning, she wakes to find Sophie's dead body floating in the pool. As the resident vagabond, she's both the only witness and the prime murder suspect.

Bree knows she shouldn't run, but her husband's death was mysterious, too. If she's going to clear her name, she's going to have to work fast. Because the killer is still out there, and she's next.
