In "Who Is the Traitor Among Us?", the Challengers of the Unknown are lured to a ruined lab by a cryptic message from Scientist X, only to be ambushed by Dimension-Man and his resurrected ally, the Iron Dictator. With clues leading to hidden inventions and a sinister trap set to turn the team against itself, the Challs must stay sharp as deception and danger collide. Written by Ed Herron and brought to life with bold art by Bob Brown (pencils and inks), this 1966 issue features a cover by Bob Brown that captures the mystery and menace of the moment.
