Adventures into the Unknown #18 (1951)

Jo, a young woman haunted by her uncle Fred Owens’s mysterious letters from Africa, grows increasingly uneasy as she learns of his death by a python and the strange, unsettling presence of a man calling himself O.B.—a man who claims to have brought Fred’s remains home and now offers to bury him in his private cemetery. As shadows lengthen and the line between fear and reality blurs, Jo begins to question whether O.B.’s kindness hides something far darker, especially when she realizes she’s never seen him without his gloves, and the ring Fred lost in the jungle seems to have vanished again.

When young Ruby Moxey answers a knock at her door to find a ghostly bat swooping past, the eerie encounter sets off a chain of unsettling events that leaves her household on edge—especially when the bat reappears, landing on her sister’s face in the dead of night. As panic spreads and the family tries to confront the phantom, they’re left grappling with a mystery that defies explanation, all while the shadow of a past long buried begins to stir.

Sheriff Wade Larson is haunted by recurring nightmares of a deadly showdown with the Laramie Kid, a notorious outlaw he’s been hunting. As the tension mounts in the dusty streets of town, the line between dream and reality blurs—until the sheriff finds himself facing not just a man, but something far more terrifying.

Claire Vaughan, a woman grappling with terminal heart trouble and a haunting sleepwalking habit, finds herself drawn into a terrifying mystery when she encounters a group of undead figures who seem to be searching for her. As the moon rises again, she must confront the chilling possibility that her sleepwalking has led her not to death, but to a sinister force that claims the dying—and that her own fate may be tied to a doctor named Noctam, whose true nature defies the living world.

In the Caribbean's forgotten Buccaneer's Cove, the ghost of Captain Jack Ballerye haunts the buried treasure he cursed before dying, warning all who seek it that he will strike down any thief. Centuries pass as fortune hunters—Spaniards, Prussians, and divers—fall victim to the phantom’s wrath, their fates sealed by eerie accidents and sudden disappearances. The treasure remains hidden, its location known only to those brave—or foolish—enough to risk the curse.

In the throne room of Empress Catherine the Great, a ghostly double of the ruler appears, claiming the throne and startling the empress with its uncanny resemblance. As guards open fire, the apparition vanishes—only for the empress to die days later under mysterious circumstances, her body bearing strange marks that hint at a violent end.

Otis Findley, the famed ghost-breaker, arrives in Athens to expose a medium named Deidameia, who claims to summon spirits through a mythical centaur guide. As he prepares to dismantle her act, the seance takes a sudden turn when the centaur spirit—revealed to be a man in a costume—comes to life with terrifying force.
