Under hypnosis, Amber hears herself saying "kind, cruel, kind of cruel." The words awaken a vague memory, but she dismisses the whole episode as nonsense.

Married detectives Charlotte "Charlie" Zailer and Simon Waterhouse are once again on the case, as the investigation unexpectedly reveals a shocking insight into Simon's psyche, in anothe gripping page-turner from the author of Lasting Damage .
