Mrs. Markleham is Annie Strong's mother. She lives with her daughter and son-in-law, and becomes known as the "Old Soldier" amongst Doctor Strong's students because she is constantly strategizing about how to manipulate the Doctor into advancing her family's standing. In doing this, she has no qualms about using her daughter. For instance, she encourages Doctor Strong to send Annie out to concerts and parties simply so that she can go along as well. Annie is ashamed of her mother's behavior but is powerless to stop it (at least before Mr. Dick brings the issue out into the open).
