Doris Buckle

In the novel Hercule Poirot's Christmas, Doris Buckle is mentioned. She works in the Combined Dairies, 23 Markham Road.

Doris goes to the cinema with Sydney Horbury on the evening of the murder. They meet there by appointment, and Horbury sees her home after the show, before returning to Gorston Hall. Doris later tells Superintendent Sugden that Horbury was with her in the cinema the whole time, proiding him an alibi for the time of the murder. Superintendent Sugden believes that she is telling the truth, as she is "a simple kind of girl", and he would know if she was lying.
