In "What Was the Staggering Secret of the 13th Floor," Stan Lee and Larry Lieber deliver a chilling twist on a classic urban legend, with Don Heck’s moody art and Artie Simek’s sharp lettering heightening the tension. When a spy holds a terrified passer-by at gunpoint in a hotel elevator, the cheerful operator calmly vanishes—revealing the building’s most unsettling truth: the 13th floor doesn’t exist. Ron Wilson’s cover, inked by Vince Colletta, captures the eerie stillness of the moment before the secret unfolds.

Willy SloaneMr. Jordan

In "What Was the Staggering Secret of the 13th Floor," a tense moment unfolds in a quiet hotel elevator when a terrified passer-by is forced at gunpoint by a spy intent on detonating a bomb. The elevator operator, unnervingly calm, simply vanishes as the spy exits on the 13th floor—only to reveal the chilling truth: there is no 13th floor at all.

Reign of Fear
4 pp · Horror-Suspense

In "Reign of Fear," a man with a split face—one side handsome, the other grotesque—uses his duality to manipulate fear and justice, revealing only the pleasing side to police while showing the hideous one to his victims. Written by an unknown author and illustrated by an unknown artist, this chilling 1975 tale from *Crypt of Shadows #18* explores the dark cost of deception in just four pages.

5 pp · Science Fiction
CarlDerek

In "I Dared to Look into the Beyond!", a desperate scientist pushes the limits of time, only to find his machine has carried him not to the past, but to a future where Earth lies empty and silent. What begins as a bold experiment in proving the non-existence of the future quickly unravels into something far more unsettling—something he wasn’t meant to see.

The Hog!
4 pp · Crime

In "The Hog!", a self-absorbed driver obsessed with dominating the road takes his arrogance to grotesque extremes, rigging his car with mirrors to savor the fear of others. When a hitchhiker warns him he’ll one day meet a bigger hog, he scoffs—until his own twisted invention reveals a monstrous vision just around the bend. The story’s chilling twist lingers long after the final panel, leaving the reader to wonder what kind of fate awaits those who think they’re untouchable.
