Mr Curle

In the short story The Herb of Death, Mr Curle is an elderly gentleman and a house guest at Clodderham Court at the time of the events in the story. He had come to discuss old books with his host Sir Ambrose Bercy. Dolly Bantry described Mr Curle as an elderly stooping old man with a beard. To her such people were always faddish. Mr Curle, for example, was a vegetarian and ate something that looked like bran for breakfast. He would talk with enthusiasm but only about his "musty books".

Among the Tuesday Night Club members, Curle was cleared as a plausible suspect in the murder of Sylvia Keene because he had absolutely no interest in nor benefit from the girls death.
