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. 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. Meanwhile Kincaid finds himself plagued by disturbing questions about several previous-- and seemingly unrelated-- cases involving members of the force. If his suspicions are correct and the crimes are linked, are his family and friends in mortal danger as well?
