Lucy

Lucy is a non-canonical character created for the film adaptation of How Does Your Garden Grow? in Series 3 of ITV's Agatha Christie's Poirot. Lucy is the cook in the household of Amelia Barrowby. The part of Lucy is played by Dorcas Morgan.

When Amelia died from strychnine poisoning, Lucy was not considered a plausible suspect. She had no motive and the food she had prepared for dinner during that night was not suitable for hiding strychnine which was very bitter. In any case Lucy ate the same food as everyone else during the meal.
