On the evening of 30th March, 2005 an arm and a leg were found in the water in the Royal Canal in Dublin. It transpired a man had been brutally murdered and dismembered and all of his body parts, apart from his head and genitals, had been dumped in the water. The murder became one of the most notorious in Irish history. This is the story of the police investigation - the methods that were used to identify the body and how they eventually caught the killers - Charlotte and Linda Mulhall. Due to the brutality and savagery of the crime, the Mulhall's became known as the Scissor Sisters. Contributors include Chief Superintendent Christy Mangan, who lead the investigation, Dr Brid McBride from Forensic Science Ireland, who worked on the crime scene and authors and journalists that covered the case in detail.
