This anthology issue contains multiple detective and crime stories. "The Masked Marvel" features a criminal named "Glitter" who operates a gang from a hidden warehouse and robs a safe expert's home, leading to a confrontation where the criminals are apprehended. "The Eye" depicts a supervillain weapon—a giant floating eyeball capable of controlling trucks—used by conspirators in an elaborate scheme, though the device ultimately fails and is destroyed. The issue also includes stories featuring Dan Dennis, Spy Hunters, Dean Denton, and Spark O'Leary, showcasing various detective and crime-fighting adventures typical of the pulp crime-comic genre.

Dudley Dance arrives at a peaceful mountain resort only to find his vacation interrupted by a brutal murder—and soon after, a second. When frightened witnesses report seeing glowing eyes at a window during a chaotic dance at the community center, Dance begins to suspect the killer might not be a wild animal at all. With the colony under guard and a mute groundskeeper named John seemingly the only one who might recognize the beast, Dance inches closer to an impossible truth.

This is an anthology containing multiple stories. The OCR text shows "Detection Notes" (an educational feature about forensic ballistics and police procedure), followed by "Captain Forsyth & Sergeant Mclean: Spy Hunters" (a military adventure), and the beginning of "The Eye Sees" (a vigilante tale). Since "Detection Notes" is a non-fiction educational segment about Col. Calvin Goddard's ballistics work and police methods—not a narrative story with plot or characters—there is no story synopsis to write. SKIP

Case of the Radium Robbery

Dean Denton, a scientific detective and former ventriloquist, travels to the Belgian Congo to retrieve a million dollars' worth of radium for a hospital—only to learn via radiogram that the shipment has been stolen by red-robed criminals. Suspecting his old nemesis, the Conqueror, Dean sets out with his assistant Carol Kane and his aide Absalom Adams, armed with a Geiger-Mueller counter to track down the thieves through the treacherous foothills toward the mysterious Magic Mountain. When the trail leads to a hidden cavern and Carol is captured, Dean must find a way to outwit the Conqueror and save her from a fate far worse than death.
