The father of Helen Sinclair was a cruel and unkind man, who bullied his daughter and was equally cruel and abusive towards her mother. He had three other children, all sons, but did not subject them to the same type of treatment that he gave his daughter and wife because they were boys. When Helen left to travel in time with the Eighth Doctor in 1963 to escape accusations of stealing the National Museum's Red Lady collection, the Sinclair family's reputation was severely damaged. His son George Sinclair attributed the stress Helen's disappearance and apparent crime as the cause for their father's early death, some years before 1998. (AUDIO: Absent Friends)
