Cora Tucker is waiting for her divorce. She is surviving by living a quiet life that consists of not much more than her job as an economics lecturer in a Liverpool college. She has few friends and a family that worries about her future. Next door neighbour Zuzanna Kowalski is murdered. Detective Sergeant Lewis thinks Cora is connected to the murder, especially when it is revealed that the accountancy firm of the separated husband of Cora launders cash for criminals. A parcel intended for Zuzanna is delivered to Cora by mistake. The parcel contains £50.000. Andrew, her separated husband, demands help from Cora to evade the police. Charming Mark, the criminal partner of Andrew, issues threats to Cora. Her mother is suspicious, and Detective Sergeant Lewis persists in her investigation. The life of Cora Tucker is no longer quiet. Somehow, though, she will have to survive.
