The Hundred Comic Monthly #3

In "Mystery of the Human Thunderbolt," Barry Allen’s life changes in an instant when a lab accident with lightning and chemicals grants him super-speed, launching him into a heroic identity inspired by the Flash of the 1940s. Now racing against time, he must confront a bizarre new threat—the Turtle Man, known as "The Slowest Man Alive"—in a battle where speed meets slowness in the most unexpected way.

In "The Man Nobody Could See," a brilliant but desperate man stumbles upon a formula that renders him invisible, using his newfound power to amass fortune in secret. Now trapped in his own invisibility, he faces a chilling choice: remain unseen forever or surrender himself to the authorities to be made visible again.

In "Mystery of the Space Mutiny," two young explorers, Tommy and Brent, stumble upon a derelict spaceship and its survivors—former crew members accused of mutiny and murder. Stranded on a harsh planet, the mutineers claim they only overthrew their captain, not killed him, and Tommy, skeptical but determined, follows a trail of mysterious light waves through space to uncover the truth.

In "The Broadway Posse," six aging Western outlaws turned city dwellers team up to take down the notorious criminal Harry Ames, but their quest for justice takes a dangerous turn when the truth about one of their own—Arthur Mills—begins to unravel.
