Agatha Christie Wiki

Margaret Jefferson was the wife of Conway Jefferson, and the mother of Frank and Rosamund. She died in a plane crash.


Margaret is not featured in BBC 1984 adaptation of the novel as she was already dead at the time of the events in the show.

In the ITV 2004 adaptation of the novel (Episode 1, Season 1 of Agatha Christie's Marple), Margaret is shown in the first scene, which is a flashback to a dinner party held during the Second World War to celebrate the birthday of Frank Jefferson. However Margaret does not have a speaking part and the actress who played her is not credited.
