Miss Tonks is another employee of Mrs. Vincent. She reveals to Robert Audley the exact dates of Lady Audley’s arrival at Mrs. Vincent’s school, thus allowing Robert to connect the timelines of Helen Talboys and Lady Audley. Miss Tonks also provides Robert with Lady Audley’s trunk, which contains labels bearing both the names of Helen Talboys and Lucy Graham—the most substantial piece of evidence in Robert’s investigation thus far.
