Alien Equivalent

In Short

Set on a colonized, corporate-exploited Mars, this 1955 science fiction short story follows Chester Farrell, an Earthman who has spent three years scraping together money to rejoin his wife and son in Cleveland, only to be ambushed by a ruthless thug named Tharp. To save his life and his hard-earned ticket, Farrell offers Tharp a fortune through a secretive, off-limits Martian game called rhakal. The narrative explores economic entrapment and cultural alienation through a darkly inventive sci-fi lens, enduring as a sharp, atmospheric tale of human desperation in a dying alien world.

The Story

Chester Farrell stands near the spaceport fence on Mars, holding his return fare to Earth after three grueling years of low wages and high living costs imposed by the Mars Mining Corporation. As he prepares to leave, a brutal, knife-wielding man named Tharp emerges from the shadows and robs him. Facing certain death once the money is stolen, Farrell stalls by promising a much larger payout. He spins a tale about winning five thousand dollars in Dankor, an off-limits Martian city, playing a mysterious local game called rhakal. Intrigued and greedy, Tharp spares Farrell's life, forces him at gunpoint to walk the desolate desert paths, and escorts him into the crumbling, impoverished alleys of Dankor.

Inside a dimly lit, foul-smelling room, several listless Martians watch a three-dimensional board game using small control panels and glowing markers. Farrell explains that they can wager using "duchal," an intangible measure of sorrow or pain. Intrigued by a pile of abandoned riches—gold, diamonds, and gems that mean nothing to the impoverished, stubborn locals—Tharp agrees to bet duchal instead of cash, believing it will be easy to pay off if they lose. Farrell guides Tharp's button presses through the complex game, though he remains trapped under his captor's watchful eye with no escape in sight.

Predictably, they lose the match. The Martians attach electrodes to Tharp's head and hook him up to a rusty, ancient machine designed to transfer the loser's physical and mental agony into the winner's brain. When Tharp fails to register any duchal on the machine's dial, he panics and draws his revolver. A dozen Martians instantly overpower him, disarming and shackling him to the floor. Farrell calmly explains the fatal flaw in Tharp's plan: because Earthmen are physically robust and emotionally insensitive compared to frail Martians, ordinary regret will not register on the machine. To generate enough agony to satisfy the debt, Tharp must experience genuine, severe physical torment. As three Martians draw sharp knives and begin cutting into Tharp's flesh to force the needle up, he screams for help. Farrell turns, walks out the heavy door, and leaves his captor to pay his debts.

How It Unfolds

• The voyage begins: Chester Farrell stands outside the Martian spaceport, clutching his hard-earned savings for a ticket back to his wife and son in Cleveland after three years of exploitative colonial labor.
• The ambush: A brutal, thick-lipped man named Tharp intercepts Farrell in the dark, pins him to the sand, and robs him at knifepoint before preparing to deliver a fatal lunge.
• A desperate bargain: To save his life, Farrell invents a story about a five-thousand-dollar payout won playing a forbidden Martian game in the off-limits city of Dankor.
• The desert march: Guarded by a stubby revolver, Farrell leads Tharp across the treacherous red sands and along the massive stone walls of the Dankor canal under the light of two moons.
• The gambling den: Entering a foul-smelling room illuminated by imprisoned fireflies, the two men watch emaciated Martians play a complex three-dimensional game involving green and brown balls.
• The wager of agony: Tharp agrees to bet "duchal," dismissing it as a harmless alternative to cash, unaware that the currency represents the direct transmission of physical and mental pain.
• The trap springs shut: After losing the match, Tharp is strapped into an electrode machine that fails to register his shallow remorse, prompting the local Martians to draw knives to extract his payment through flesh and blood.

The People

• Chester Farrell wants nothing more than to escape the economic trap of Mars and return to his family in Cleveland. Standing in his way are corporate exploitation, poverty, and a murderous robber. He survives through quick thinking and cunning, ultimately turning his captor's greed against him to secure his freedom and money.
• Tharp wants easy money and operates entirely on brute force and intimidation. Standing in his way is his own ignorance of Martian culture and biology. He ends up trapped in the gambling den, helplessly paying off a crushing debt in agonizing physical pain while shackled by metal bindings.
• The unnamed Martian gamblers want to extract their due through their traditional system of exchange. Standing in their way are foreign intruders who know nothing of their customs. They remain detached, methodical, and strictly committed to settling debts, indifferent to human violence.

In Its Own Voice

"Only in the sly and mentally skillful game of Duchal might sons of the red planet emerge gloriously from their shells."

This opening line establishes the deep-seated cultural pride and quiet rebellion of the fragile Martian race against human dominance.

"During the voyage to Earth, he would be the only passenger and would occupy a coffin-like compartment. Every other available foot of space would be filled with valuable ores."

Farrell reflects on the predatory economics of the Mars Mining Corporation, which makes returning home exorbitantly expensive while packing ships with cargo rather than returning colonists.

"The Martians are constructed in such a way that the agony of another person, implanted in their minds, is very pleasant to them."

Farrell explains the unsettling premise behind duchal, illustrating the profound emotional and physiological gulf dividing humanity from the indigenous inhabitants of Mars.

What It's Really About

The story examines the brutal mechanics of colonial exploitation, where political bodies and business interests collaborate to trap laborers through manufactured debt and inflated travel costs. It explores the psychological chasm between conqueror and conquered, contrasting human physical strength and emotional bluntness with Martian sensitivity and silent resentment. Beneath the sci-fi trappings of alien cities and strange machinery lies a critique of economic entrapment, showing how systems designed to exploit the weak can ultimately be subverted by those who understand the rules better than their oppressors.

Why Read It Today

Readers who appreciate mid-century science fiction with sharp sociological underpinnings, gritty atmosphere, and clever twist endings will find much to admire here. It feels like a brisk, atmospheric noir transplanted onto a bleak, dusty alien frontier, evoking the claustrophobia of a frontier town where corporations hold all the cards. While the prose carries the brisk, unvarnished pulp conventions of its 1955 magazine origin—and depicts Martians through a mid-century lens of passive decline—the story moves with relentless momentum. What stays with you is the chilling final image of poetic justice: a violent man trapped not by iron bars, but by an alien economy that measures currency in raw, screaming agony.
