Major Malcolm Wheeler-Nicholson was stationed in Paris in 1919 following WWI. There he met Elsa Karolina Bjorkbom, a young Swedish woman studying fashion and they fell in love. One of the Major’s pulp adventure stories “The Monastery of Blue Death,” (The Popular Magazine April 1930) has hints of that meeting.
It’s quite a romantic tale that begins in Paris immediately after World War I and is filled with autobiographical details. In the comic derived from the story, “Monastery of the Blue God,” beginning in New Adventure Comics #14, March 1937, the likeness of the heroine to Elsa, as drawn by Pad Munson, is striking.
