Margaret (The Tragedy at Marsdon Manor)

Margaret is a non-canonical character who was created for the film adaptation of The Tragedy at Marsdon Manor in Series 3 of ITV's Agatha Christie's Poirot. She is the receptionist/secretary of Dr Geoffrey Bernard and is portrayed by Hilary Sesta.

She contributed some humour to the proceedings as part of her role. When Poirot called on Dr Bernard at his clinic, he asked her to tell the doctor that "it's Hercule Poirot". Margaret told the doctor that there's a patient suffering from "ercule poirot" and he thinks it is serious.
