Betty Archdale

In the novel Sparkling Cyanide, Betty Archdale was a former parlourmaid at the Barton household. Lucilla Drake had found her impertinent and careless. Mrs Drake also claims that she had broken six glasses of the finest type at the same time. At the time of Rosemary Barton’s ‘suicide’, Betty had suspicions about it being murder.

After leaving her job with the Bartons, she was employed by a Mrs Rees-Talbot.
