Dolly Maltravers

In the novel Why Didn't They Ask Evans?, Dolly Maltravers is a friend of Mrs Rivington. Dolly was taken to court after shooting a dressmaker. The law firm of Spragge, Spragge, Jenkinson & Spragge  acted for her. When Bobby Jones impersonated a member of the firm to call on Mrs Rivington to get more information about Alan Carstairs, Mrs Rivington was  very curious about what happened  in the Dolly Maltraves case. Bobby was able to drop a few (fabricated) hints which served as conversation openers and secure her cooperation.
