Amazing Man Comics #20

When a mysterious Indian approaches John Aman to warn him of danger, he's gunned down before he can speak—and the Amazing-Man finds himself chasing a trail of falling rockets from the sky, each carrying dead bodies. Investigating in La Paz near a recent crash site, Aman uncovers an underground operation run by his arch-enemy the Great Question, who's kidnapping Indians and launching them into space, and the situation grows desperate when Zona is captured and the Great Question vanishes before Aman can stop him. With rockets as his only lead, Aman races against time in a high-stakes aerial pursuit to save his assistant and dismantle the Great Question's sinister scheme.

When a mysterious plague strikes sailors at a naval base, Rocke Wayburn arrives to investigate—and quickly zeroes in on a suspiciously cheap banana operation at the docks. After getting ambushed and knocked unconscious, he disguises himself to infiltrate the fruit ship and uncover the murderous scheme, only to find himself cornered and outnumbered by Slug Gunther's men. With his back literally against the wall, Rocke fights for survival while the conspiracy's true mastermind closes in.

Trapped, tricked into a sub-zero refrigerator, and nearly dumped into molten tungsten, the Iron Skull must use his unique metal body and wits to expose the conspiracy before the plant is destroyed.
