Edith - a successful, career-focussed woman in her 20s - was married to Percy Thompson. Their marriage was not a particularly happy one, and she began an affair with a young man named Freddie Bywaters, who was in the merchant navy.
One evening Freddie fatally stabbed Percy, and both Freddie and Edith were arrested, tried and found guilty of murder.
Sasha and Jeremy join forces with one of Edith's few living relatives, Nicki, to examine correspondence between the lovers and ask whether Edith was responsible for the murder as a result of her influence on Freddie's actions.
