About the series
Secret Agent X9, a 1948–1950 Atlas Comics series spanning nine issues, brought the classic newspaper strip hero into the burgeoning post-war comic book landscape. While less celebrated than the strip itself, this short-lived run is a notable artifact of Atlas's early crime and adventure output, offering a grim, shadow-drenched take on international espionage.
