The murder of a young prostitute in Stockholm, Sweden, causes Anne Petersson, a criminal psychologist, to be called in by the police to advise and help in their investigations. The discovery of a photograph in the victim's personal possessions, a man who bears an uncanny resemblance to her own father leads Anna to travel to London, not only to liaise with the English Authorities but also to search for the truth behind the photo. Whilst she is in UK another murder in Wimbledon appears to be connected to the case in Stockholm. Her investigations eventually take her to Scotland where she meets a Scottish jeweler, Duncan Macmillan, the sole importer of certain crucifixes that appear relevant to the case. Many questions need to be answered before Anna discovers the facts behind the case as well as the truth that relates to her own life.
