Red Witch of Mercury

In Short

This fast-paced science fiction adventure follows Jaro Moynahan, a cynical gun-for-hire drawn to Mercury to navigate a purported revolution. He quickly discovers that the conflict is a manufactured ruse designed by Earth-based business interests to maintain their colonial grip on the planet’s lucrative resources. Along with a spirited secretary and a resourceful government agent, Jaro maneuvers through a labyrinth of secret passages and political double-crosses. It remains a classic of 1940s pulp fiction, notable for its atmospheric world-building and its cynical, high-stakes tone.

The Story

The story opens at "Mercury Sam's Garden," a bustling, heat-drenched nightspot, where Jaro Moynahan arrives seeking the "Red Witch," a singer named Miss Mikail. Jaro is a professional soldier of fortune, summoned to the planet under mysterious pretenses. He soon finds himself in the crosshairs of the Latonka Trust, a powerful corporate combine led by Albert Peet, which monopolizes the planet's native wine trade. Peet offers Jaro a small fortune to assassinate Karfial Hodes, a local leader supposedly fomenting a violent uprising.

Suspicious of the offer, Jaro teams up with Joan Webb, Peet’s disillusioned secretary, and Irving Landovitch, an agent for the Terrestrial Intelligence Service. Their investigation reveals that the "revolution" is a fabrication—a calculated scare tactic designed to block the Earth Congress from granting Mercury independence. Peet and his associates are attempting to paint the peaceful Mercurians as dangerous radicals to preserve their own profit margins.

As the "Festival of the Rains"—a period of intense local revelry—arrives, the tension boils over. Jaro and his companions are kidnapped and thrown into a sprawling, ancient network of secret tunnels that honeycomb the planet's architecture. While navigating this dark, subterranean maze, they discover that Hodes has already been murdered by a poisoned dart, a move intended to silence the only man who could expose the conspiracy.

The situation escalates into real, bloody street fighting between colonial guards and ruthless Venusian mercenaries hired by Peet to stage the fake riots. Jaro eventually corners the mercenary commander, who admits the entire plot was a theatrical stunt to manipulate Earth’s political perception. With Peet exposed and the mercenaries opting to flee the planet, the "revolution" collapses. In the aftermath, Jaro and Landovitch orchestrate a complex scheme to secure Joan a position as a secretary for the Martian royal court. They reveal their manipulation to a skeptical but ultimately willing Joan, and the three of them board a super-liner for Mars, leaving the wreckage of the Latonka Trust behind them.

The People

Jaro Moynahan is a professional soldier whose expertise is death. He begins the story as a cynical mercenary but evolves into a man seeking truth amidst political corruption. He is defined by his ability to remain calm under extreme pressure and his sharp, probing intellect.

Joan Webb is a whip-smart secretary who initially wants only to escape her employment at the Latonka Trust. She is frightened by the violence but proves to be an indispensable, quick-witted partner to Jaro. She ends the journey as a resilient woman ready to forge a new path on a different planet.

Albert Peet is the desperate, sweating head of the Latonka Trust. He wants to maintain his lucrative control over the wine trade at any cost, including murder and political deception. His inability to see the impending collapse of his power leads to his eventual downfall.

Irving Landovitch is a T.I.S. agent who provides bureaucratic legitimacy and a steady hand during the street fighting. He is Jaro’s foil, frequently bantering about their "disreputable" pasts while helping to orchestrate the final move against the Trust.

In Its Own Voice

Jaro is introduced as a man defined by his lethal profession as he prepares for his newest, most dangerous contract on Mercury.

"The night was very hot; but then it is always hot on Mercury, the newest, the wildest, the hottest of Earth's frontiers."

The narrative establishes the oppressive, alien environment that makes every action in the story feel urgent and potentially fatal.

"I'm Jaro Moynahan, Miss Webb. I think Albert Peet forgot to introduce us. There's some skullduggery going on here that I'm particularly anxious to get to the bottom of."

Jaro introduces himself to Joan in the aftermath of a shootout, signaling his shift from a mere hired gun to an active investigator.

What It's Really About

At its core, this story is a critique of the intersection between corporate greed and colonial politics. It asks how far a monopoly will go to protect its bottom line, suggesting that the most dangerous "revolutions" are often those manufactured by the elite to maintain their own power. The book explores the tension between passive resistance and active intervention, questioning whether justice can be achieved in a system that is fundamentally rigged. By juxtaposing the ancient, subterranean world of the Mercurians against the modern, ruthless tactics of the Earth-based Trust, the story highlights the clash between tradition and exploitative progress, ultimately arguing that the truth—even when uncovered by a mercenary—is the only weapon capable of toppling a corrupt regime.

Why Read It Today

Readers who enjoy the brisk, no-nonsense pacing of 1940s pulp science fiction will find this a compelling read. It captures the essence of a frontier story set on a hostile, alien world, where the heat is as much a character as the villains. You will appreciate the sharp, witty dialogue between Jaro and Joan, which keeps the tone light even when the stakes are at their highest.

However, the reader should be prepared for the genre conventions of the era. The prose is functional rather than flowery, and the characters often fit into archetypes typical of the period's magazines. Some of the world-building relies on "yellow-eyed" tropes common to mid-century fiction, which reflects the period’s attitudes toward "the other" and race. Despite these dated elements, the core of the story—a high-stakes game of political intrigue—remains engaging. It is a quick, atmospheric journey that feels like a classic noir film set against a sweltering, subterranean sci-fi backdrop. If you enjoy stories about unlikely alliances and clever heroes outsmarting powerful corporations, you will find this a satisfying, if fast-paced, experience that stays with you for its grit and its surprisingly clever conclusion.
