About this Issue

Marvel Mystery Comics #3 (January 1940) is an early-run cornerstone of Timely's flagship anthology, carrying forward the full roster of characters who would define Marvel's Golden Age identity — the Human Torch, the Sub-Mariner, the Angel, the Masked Raider, and Ka-Zar the Great — with no substitutions or drop-offs only three issues into the series. Most significantly, the Sub-Mariner chapter introduces Betty Dean, the police officer who becomes one of the era's most consequential supporting characters: her persuasion of Namor to fight for the Allies rather than against humanity is the narrative hinge that transforms the Sub-Mariner from a straight antagonist into an anti-heroic force for good, a moral pivot whose echoes reach all the way to modern Marvel continuity. The issue also carries the continuation of Ben Thompson's serialized comic adaptation of the Ka-Zar pulp prose stories, representing one of the earliest examples in comics history of multi-issue narrative serialization directly imported from pulp magazine source material. On the production side, the issue debuts a redesigned title logo drawn from Timely's pulp magazine house style, a small but visible marker of Martin Goodman's effort to unify his publishing empire across formats.

In "The Menace from Mars," the Raider finds himself caught in a dangerous game of deception and greed when a gang of outlaws tries to drive a rancher off his land to seize hidden gold and oil. Written and illustrated by Al Anders, this 1940 adventure blends frontier tension with early superhero flair, while Alex Schomburg’s striking cover captures the story’s high-stakes drama.

History

Published by Timely Publications with a cover date of January 1940, the issue was produced by the same core creative team that launched the title: Carl Burgos on the Human Torch, Bill Everett on the Sub-Mariner, Paul Gustavson on the Angel, Al Anders on the Masked Raider, and Ben Thompson on Ka-Zar. Thompson was adapting, chapter by chapter, the Bob Byrd pulp story 'King of Fang and Claw' from Goodman's own Ka-Zar pulp magazine (1936), making the comic strip adaptation a deliberate cross-media recycling of content Goodman already owned. The issue is a textbook example of the anthology model Timely used in these early issues: five or more genre-distinct stories per 68-page package, each self-contained enough for new readers yet building ongoing threads for regular buyers — a formula that would underpin Marvel Mystery Comics through its entire 92-issue run.
