Ellis (Lord Edgware Dies)

In the novel Lord Edgware Dies, Ellis is Jane Wilkinson's personal maid at her new accommodations.

She is a short, middle-aged woman with grey hair, and wears pince-nez.

Jane Wilkinson had borrowed a pair of Ellis' pince-nez to assist in her disguise as Mrs. Van Dusen. She also sent Ellis to collect a parcel from a shop in Paris. Unbeknownst to Ellis, that parcel contained the gold case which Jane would later fill with veronal, and put into Carlotta Adams' handbag.
