In February 1994 Janet Leach, a mother of five from Gloucestershire, was at home making her children’s tea when the phone rang. Janet was on an access course which when completed would enable her to train as a social worker. Janet was also 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 in order to assist them and safeguard their rights.

With Janet no longer involved in the police interviews, Fred West refuses to speak.

The routine life of Janet Leach is dramatically transformed when she sits in as an 'appropriate adult' on interviews with serial killer Fred West, who within minutes makes a shocking confession.

With Janet no longer involved in the police interviews, Fred West refuses to speak to the police. His wife Rosemary is similarly uncooperative, and Janet receives a call asking her to resume her duty.

When Anna McFall's remains are found, Fred suggests to Janet their resemblance is significant.
