Secrets of the Unknown #207

In "The Hidden Valley!", a thousand-year-old tribe's desperate attempt to reach Mars through a mysterious device backfires when the Martians exploit it to place the entire community in suspended animation. When a modern explorer stumbles upon the ancient 'thoughtscope', they unwittingly trigger a chain of events that could awaken the long-frozen inhabitants—and unravel a secret buried beneath the sands for centuries.

In the silent void of space, three men awaken to find themselves stranded after being ejected from a malfunctioning rocketship. With no air, no hope, and a mission to deliver criminals to Mars, they must use their wits and the ship’s remaining systems to turn the vessel around—before it’s too late.

In "Build Me a Machine!", a desperate dictator demands a time machine to rewrite history, offering gold and the secrets of the H-Bomb to secure his escape from a failing war. The scientist complies, but when the machine activates, the dictator is sent not to the past he intended—but back to the moment he was born, a helpless infant in a world he no longer remembers.

In "The Footprints," a young boy's search for elves beneath a rock leads to a moment of quiet wonder—and a lesson in belief—when his mother gently urges him to stop looking. Though he walks away, the magic lingers, and the stones he left behind are transformed into gold, a fortune lost to doubt.
