She was portrayed on radio by Agnes Moorehead, who was followed by Margot Stevenson, Marjorie Anderson, Lesley Woods, Grace Matthews, and Gertrude Warner.

Older fans resented her intrusion, whereas newer readers, perhaps more familiar with the radio show than the pulp novel, accepted her readily.

[1] In the DC Comics book series The Shadow Strikes!, Margot is the daughter of a wealthy Southern land owner and a black prostitute.

Her father, Dr. Reinhardt Lane (Ian McKellen), is a scientist working to develop a new type of power source, using an implosive device to be contained within a beryllium sphere, which the villainous Shiwan Khan (John Lone) tries to turn into a weapon.

After they go out to dinner together, Lamont realizes that Margo has psychic powers and fears that she may uncover his secret identity as the Shadow if they spend more time together, so he vows never to see her again.

However, when Khan begins controlling her father's mind, Margo approaches Lamont and Police Commissioner Wainwright Barth (Jonathan Winters) for help.
