Mary West, a local pastor, and a pillar of the community, played a crucial role in assisting the police with their investigation into Leigh Sabine. Leigh, who was Mary’s mother’s neighbour, often attended the West family gatherings. Despite Leigh's claims of having five children, Mary found it odd that there were no photos of them in her flat. Leigh had also mentioned, inconsistently, that one of her children had died and that her husband John had left her for another woman.
Leigh would often share elaborate stories about her past as a cabaret performer and her supposed fame in New Zealand and Australia. However, Mary later discovered these tales were fabrications. Leigh had deceived the entire community with her lies. In reality, Leigh had murdered her husband and concealed his body for 18 years.
There was a time when Leigh cryptically said to Mary, "You know, Mary, don't you? You know what I have done?" At the time, Mary did not understand the implication, but in hindsight, it all made sense. Mary’s observations and information were invaluable to the police, helping them identify the victim and uncover key details about the case. Her efforts were instrumental in revealing the truth about Leigh Sabine, a woman who had masked her sinister deeds behind a facade of fabricated stories and false identities.
