Margot returns to her well-to-do family in England on the eve of her Aunt Chloe's murder trial-she is accused of fatally stabbing her twin sister with a kitchen knife in the garden. Nothing has been the same since Claudia's body was found: her 14 year old daughter Lynette refuses to leave her bedroom, the paparazzi are relentless, and Tikki, the family's beloved Abyssinian, goes to stay with the neighbors. When another body, whom no one recognizes, shows up facedown in the pond while the family is in the midst of Chloe's trial, doubt and suspicion intensify-and no one can be trusted.

These scandalous deaths can't be related, can they? If Chloe is locked up, another murderer must be lurking about. Since no one is trying to solve the puzzle in the garden, Margot decides it's up to her to investigate. She soon finds herself getting in too deep-and running from a killer who's bent on staying one step ahead of her at all costs...
