This anthology issue contains at least three distinct stories. The first follows Jerry White as he investigates the mysterious reappearance of an old man named Mr. Dillon, who claims to have been cared for by a caretaker named Fred and possesses centuries-old clothing, suggesting a supernatural connection to the past. "Diary of Doom" features Dr. George Fielding's account of his transformation into a murderer and werewolf after encountering a strange, greedy manner in a shadowy place, with authorities unable to locate him based on the diary alone. "True Ghosts in History: The King of Sweden and the Little Grey Man" recounts the legend of King Charles XII of Sweden seeking out a spectral figure in grey to learn the fate of his defeated armies, culminating in a supernatural encounter in the Finnish woods where the ghostly visitor's icy touch seals the king's doom.

Gail FosterMr. FosterBill CampbellDr. RavpemiCountess Zara

When Gail Foster receives a haunting vision of her lost love Bill Campbell—missing for seven years after his plane went down in Transylvania—she becomes convinced he's alive and trapped by something unspeakable. Her search through old European records leads her to the House of Zara and a cryptic family motto, and when she invokes another vision to learn Bill's fate, a terrifying visitor materializes with answers far worse than she imagined. "The Vampire Vision," illustrated with atmospheric dread, pulls Gail into a nightmare that blurs the line between psychic premonition and horrifying reality.

Sold to Satan

Dan DillonJerry WhiteFred AdamsSatan

When Dan Dillon inherits a mysterious mansion from his estranged stepfather, he discovers too late that the property comes with a sinister price—the caretaker Fred Adams is far more than he seems, and a dark ceremony is underway to claim Dan's young body for an ancient evil. Trapped in a crumbling house haunted by supernatural forces, Dan must race through shadowy corridors and desperate confrontations to uncover the truth about his stepfather's bargain and find a way to stop the supernatural threat closing in on him. Written by J.R. White with interior art by an uncredited artist, "Sold to Satan" is a classic tale of supernatural terror and hidden damnation from *Adventures into the Unknown* #12 (1950).

When Witches Walked

Alice KytelerJohn De NotinghamRichard De StoweIsobel GowdieJulien CoxLyddie Shears

In 1950, Adventure into the Unknown presents a chilling historical look at the witch trials of medieval England, examining the real confessions and testimonies that fueled centuries of fear and superstition. Through vivid accounts of figures like Alice Kyteler, Julien Cox, and Lyddie Shears, the story explores the dark practices witches were said to employ—from summoning familiar spirits to transforming themselves into animals to gain forbidden wealth and power. A fascinating and eerie window into how belief in witchcraft gripped even civilized minds, proving that some legends refuse to fade from history.

Case of the Ghostly Passenger
1 pp
Captain Wintour

Captain Wintour offers a lift to a mysterious, exhausted stranger on a bridge in Yorkshire, but the silent passenger proves deeply unsettling—so much so that the captain eventually abandons his attempts at conversation. When they arrive at a village inn, the encounter takes an unexpected turn that suggests this hitchhiker may be far more than he appears.

Diary of Doom

George FieldingDr. StantonMona

Dr. George Fielding's diary entries reveal a chilling account of his arrival at the remote settlement of Howling Creek, where he was sent to establish a medical practice—only to discover something far more sinister lurking beneath the frozen wilderness. As Fielding grows suspicious of the strange inhabitants and the wolves that seem to stalk his every move, the line between the natural and the supernatural begins to blur in terrifying ways. Presented as evidence in a Canadian courtroom where Fielding stands accused of murder, his diary forces a jury to reckon with a story so bizarre that even Dr. Stanton, who warned him away, may hold the key to understanding what truly happened in that forsaken place.
