"Appropriate Adult" is a two-part drama telling the story of how Gloucester housewife Janet Leach (Emily Watson) played a key role in uncovering the crimes of serial killers Fred and Rosemary West. Janet was on an approved list of "appropriate adults" - volunteers who can be asked by the police to sit in on interviews with minors or vulnerable adults to assist them and safeguard their rights. In February 1994, Janet was asked to attend interviews with Fred West. He began to view her as his confidante and often chose to disclose previously unknown facts and the details of his crimes to her. When Fred deliberately misled the investigating officers, Janet threatened to turn her back on the case unless he told the truth. The drama centres on the period of time between Fred West's arrest, his suicide in 1995 and the conviction of his wife, Rosemary. Dominic West portrays Fred and Monica Dolan plays Rosemary. It premiered on ITV in September 2011.
