In a quiet Dublin suburb, within her pristine home, Eleanor Costello is found hanging from a rope. Detective Chief Superintendent Frankie Sheehan would be more than happy to declare it a suicide. Four months ago, Frankie's pursuit of a killer almost ended her life and she isn't keen on investigating another homicide. But the autopsy reveals poorly healed bones and old stab wounds, absent from medical records. A new cut is carefully, deliberately covered in paint. Eleanor's husband, Peter, is missing. With the suspect pool growing and mysterious calls to Frankie's phone implying that the killer is closer than anyone would like, all Frankie knows is that Eleanor guarded her secrets as closely in life as she does in death.
