The discovery in 1961 by three cavers of a sack containing human bones in a disused lead mine close to the town of Caswell near the Gower Peninsula, South Wales, would finally resolve a mystery more than 40 years old. In the December of 1919 26 year old former chorus girl, Mamie Stewart, and her husband George Shotton, some 13 years her senior, both vanished from a Swansea hotel. With only a trunk containing women's clothing, jewellery and vitally, a piece of paper with Mamie's parents address on it, the Police followed up on this lead. The Police interviewed the parents who told them Mamie had written them letters saying George was a violent and abusive husband and that she feared for her life. Mamie had left home in Sunderland at the age of 15 to purse a stage career, eventually some years later falling for fellow wearsider Shotton, and after marrying they relocated to Caswell. During the investigation of the missing persons case , it was found that Shotton was already married and father to a son with another woman. He was tracked down, charged and convicted for bigamy and served 18 months of hard labour, however the Police were convinced he had killed his second wife. After the remains were recovered and identified to be Mamie, the police attempted to locate Shotton, but unfortunately he had died some 3 years prior in 1958 aged 78.
