Detective Comics #48
In "The Secret Cavern," a startling discovery beneath Fort Knox sets off a dangerous chain of events when a man stumbles upon a hidden cavern, leading a gang of crooks to manipulate his daughter into believing she's committed murder—just to force her father to reveal the cave's secret. Written by Bill Finger and brought to life with bold, early Batman-era art by Bob Kane, with inks by Jerry Robinson and George Roussos, this 1941 thriller blends suspense and intrigue in a story that’s as much about deception as it is about the treasure beneath the nation’s vaults. The cover by Bob Kane, Jerry Robinson, and George Roussos captures the tension perfectly, a 10-cent mystery in a world where trust is the rarest commodity.
In "The Secret Cavern," a chance discovery beneath Fort Knox sets off a dangerous game when a crooked gang manipulates a man’s daughter into believing she’s committed murder, all to force her father to reveal the hidden cave’s secret. Written by a team whose names are not listed here, the story unfolds with tense suspense and the kind of old-school mystery that defined early superhero comics.
