The main visible story involves a group of explorers who venture into an unexplored area where they encounter a large yellow creature and discover encrusted jewels.

Contains 4 stories
Jewels of the Deep
8 pp · Horror-Suspense

Two unnamed men on a secret naval mission dive beneath a reef-strewn sea to test experimental underwater equipment, only to stumble upon colossal pearls hidden in the shallows—jewels that prove far more sinister than their glittering beauty suggests. As they investigate the source of these treasures, they discover a giant mollusk whose connection to the pearls hints at a dark and deadly mystery that has claimed countless lives. What begins as curiosity becomes a desperate race for survival when the creature's true nature is revealed.

The Mountain Ghost
8 pp · Horror-Suspense
Jeremiah SharpAbigail CrockerClem McBrideJeff SparksThe Ghost of Haunted MountainPa SparksTip Sparks

In the Ozarks village of Dogwood Bend, young Tip Sparks faces losing his family farm to the scheming Jeremiah Sharp, who claims the original settler—Tip's grandfather—was never properly buried on the land. Desperate and courageous, Tip ventures up the fearsome Haunted Mountain seeking aid from the legendary Ghost, a wronged man whose supernatural power punishes those who stray from righteousness. What unfolds is a tale of spectral justice, scattered remains, and whether even a ghost's magic can undo a legal claim and save a boy's home.

Signals of Doom
3 pp · Horror-Suspense
JoeGeorge FellerJack Simms

At a remote radar outpost in Washington's wilderness, technicians Joe and George Feller detect a baffling blip on their scope—something too strange to be any conventional aircraft. When an unexpected visitor arrives at their isolated station, the nightmare becomes terrifyingly real. A tense blend of Cold War paranoia and creature-feature horror, "Signals of Doom" asks what happens when cutting-edge military technology meets an ancient supernatural threat.

Where the Fire Fell!
8 pp · Horror-Suspense
DirkFrieda

Dirk and Frieda, a married jungle doctor-and-nurse team in the Belgian Congo, see a chance to strike it rich when they're invited into the mysterious territory of the Jebanoe people—where a sacred lake glimmers with treasure. But greed and betrayal set a horrifying chain of events in motion, as the contaminated waters of that ancient, otherworldly lake exact a price far beyond anything they bargained for. Written and illustrated by the acclaimed team behind this 1954 horror-suspense tale, "Where the Fire Fell!" is a chilling reminder that some prizes are never meant for mortal hands.
