Fan Casting Emily Inglethorp in The Mysterious Affair at Styles

Emily Inglethorp is the matriarch of the Cavendish family. She is a socialite and is heavily involved in fundraising for the war effort. Technically, she is John and Lawrence's step-mother, but she raised them from a very young age and they've always considered her their mother. She is known to be very generous, but her generosity also notoriously comes with strings attached. She is murdered by strychnine poisoning, and her murder is the subject of the novel.
