Marlene Buckle

In the novel Elephants Can Remember, Marlene Buckle is a young girl working at Williams & Barnet, the chemist's shop in Chipping Bartram. Ariadne Oliver stopped by and made an enquiry about lipstick in order to stage manage an encounter with Marlene in order to get the address of her mother who used to work as a part time cleaner at the Ravenscroft household. Marlene was pleased to meet Ariadne and also said her mother would be very happy to have a visit from her. They seemed to know Ariadne Oliver from long ago although the context is not explained.
