Sally Legge

In the novel Dead Man's Folly, Sally Legge (née Carstair) is the wife of physicist Alec Legge. She and her husband had rented Mill Cottage at the Nasse House estate for three months as part of a period of rest prescribed by the doctor for Alec. During the fete at Nasse House, Sally plays the fortune teller. She was originally meant to play the dead body in Ariadne Oliver's murder hunt but somehow she was roped in to do fortune telling. "Blame it on Jim Warburton," she tells Poirot.

Later, Poirot meets Sally at the folly on her knees searching for something. Poirot surmises that she had left the fortune telling tent during her tea break and come to the folly for an assignation with Michael Weyman. In the process, she had dropped an aeroplane charm which she usually wore on her wrist. Sally confides in Poirot that she is unhappy with her marriage. She thought coming to Devon for a holiday would make Alec better, but he is just as moody and detached as always.

Sally knew Michael from before her marriage. Sally had been a painter and lived in Chelsea.
