Challengers of the Unknown #4

In "The Riddle of the Star-Stone," Professor Brandon’s assistant Vreedl vanishes with a mysterious artifact forged by an ancient sorcerer, setting off a dangerous race to recover it. With the first gem already in place, Vreedl transforms into a flaming figure, unleashing chaos to buy time while he hunts for a second gem to complete his dark ambition.

In "The Dozen Dooms of Adam Strange!", the hero is hurled into a series of escalating perils after a sudden zeta-beam transport lands him in the midst of a bizarre new threat on Ranagar. With a wave of fanatical doll mania sweeping the planet and Alanna urging him to a mysterious isolationist world, Adam must unravel a plot involving hidden bombs, deceptive appearances, and a race against time—before the next doom strikes.
