Mrs Trollope is a non-canonical character created for BBC's 1987 adaptation of Nemesis. She is the postmistress in the local general store/post office at Abbey Dulcis (the town that is the parallel of Jocelyn St. Mary from the original novel. Mrs Trollope is portrayed by Marlene Sidaway.
When Miss Marple sees Anthea Bradbury-Scott walking to the post office with a parcel in hand, she suspects that it migth have something to do with what she had been asked to investigate. Miss Marple later goes to the post office and, by pretending to be forgetful and to have posted a parcel to the wrong address, managed to get Mrs Trollope to reveal the destination of the parcel. Miss Marple next asked the solicitors Messrs Broadribb and Schuster to trace the parcel and identify the contents. Although not shown on screen, the parcel contained the bright eye-catching cap and sweater which someone had worn while pushing a statue down onto Miss Elizabeth Temple in an attempt to kill her.
