New York Times bestselling author Deborah Crombie’s Scotland Yard detectives Duncan Kincaid and Gemma James are drawn into separate investigations that hold disturbing—and deadly—complications for their own lives.

On a beautiful morning in mid-May, the body of a young woman is found in one of Notting Hill’s private gardens. To the surrounding residents, the pretty girl in the white dress looks as if she’s sleeping. But Reagan Keating has been murdered, and the lead detective, DI Kerry Boatman, turns to Gemma James for help. She and Gemma worked together on a previous investigation, and Gemma has a personal connection to the case: Reagan was the nanny of a child who attends the same dance studio as Toby, Gemma and Kincaid’s son.

Gemma soon discovers that Reagan’s death is the second tragedy in this exclusive London park; a few months before, another victim died in an accident. And when still another of the garden residents meets a violent end, it becomes clear that there are sinister forces at play within the intimate walls of this private square. Boatman and Gemma must stop the killer as Gemma realizes she holds a child’s fate in her hands.
