Adventure Comics #39

In "The Suicide of Major Duval, Part 2," a 1939 Adventure Comics installment written in character as Steve Carson, the mystery deepens as the story weaves in real-world forensic curiosities—like the uniqueness of human ears and the origins of the term "gum-shoe detective"—all while maintaining a gripping, suspenseful tone. The cover by John Richard Flanagan captures the noir intrigue of the tale, a 10-cent glimpse into early comic book storytelling that blends crime-solving lore with serialized drama.
