The Sphere of Sleep

In Short

This science fiction short story follows two crew members of a Titan expedition, Brad Nellon and Big Tim Austin, as they navigate a lethal storm. Nellon, driven by a jealous desire to claim a woman named Laura, intends to murder his companion. Their journey takes a surreal turn when they discover a mysterious, ancient facility containing a glowing green sphere. The narrative explores themes of guilt, obsession, and the distorting nature of reality, ultimately trapping the protagonist in a chilling, ironic confrontation with his own choices.

The Story

On the frigid, tempestuous satellite of Titan, Brad Nellon struggles with a singular, consuming purpose: he must kill Big Tim Austin. Nellon blames Tim for his failure to win the heart of Laura, a woman back on Earth, and he views the harsh Titanian wilderness as the perfect, untraceable setting for his crime. As the two men trek through the ice-choked terrain to recover scientific equipment, Nellon waits for an opportunity to push Tim into a deadly chasm near a landmark called Tower Point.

Their journey is interrupted when a fall sends them both tumbling into a gorge, landing them near an exposed, bronze-colored structure in the ice. They discover a massive, ancient door that hums into life, revealing a network of alien corridors and rooms. Inside, they find a central, circular chamber dominated by a giant, glowing green column. As they approach, Nellon experiences a wave of artificial peace and euphoria, his dark thoughts of murder seemingly validated as noble and correct. A sudden, jarring collision with Tim breaks the trance, and they discover a green-lit inner sanctum filled with hundreds of dormant, human-like figures lying on platforms.

Driven by curiosity and a desire for fame, Tim forces open the inner chamber to investigate. The emerald radiance floods the room, and Tim immediately collapses into a deep, dream-filled stasis. Nellon, caught in the same lulling pull, fights his way to the threshold, driven by a frantic, survival-based fear. He manages to seal Tim inside the chamber, trapping him in the eternal slumber of the alien machine.

Satisfied that he has finally eliminated his rival—and imagining a future where he returns to Earth to marry Laura—Nellon makes his way back to the expedition’s camp. However, he finds the valley completely deserted. The ship is gone. As he stands alone in the howling, indifferent wind, he realizes that his time in the chamber was not a mere moment, but an epoch. He is left to face the freezing death he had once planned for his companion, realization dawning that while Tim will eventually awaken among the dreamers, he is destined to perish in the cold.

How It Unfolds

The murderous trek Nellon and Tim traverse the brutal Titanian landscape, with Nellon nursing a secret, mounting hatred for his companion. He views the treacherous terrain as the ideal backdrop for a murder that would clear his path to Laura.

The discovery at the falls After a near-fatal slip leads them to the bottom of a gorge, the men uncover a mysterious metal door hidden within the ice. Their combined strength triggers the mechanism, granting them access to a silent, alien complex.

The lure of the sphere Deep within the facility, the two men encounter a green, glowing column that emits a pacifying, hypnotic force. Nellon finds his own dark desires amplified and justified by the machine’s influence until a physical collision snaps him out of it.

The final trap Tim attempts to explore the inner sanctum and is instantly incapacitated by the sphere's rays. Nellon, managing to resist the pull, seals Tim inside, convinced that he has effectively removed his rival from existence.

The hollow victory Returning to the extraction point, Nellon finds the expedition has long since departed. He realizes he has been under the sphere's influence for months, leaving him stranded in a desolate wasteland while Tim remains preserved in an eternal, dream-filled sleep.

The People

Brad Nellon is the story's embittered protagonist, defined by his deep-seated resentment toward Tim and his possessive obsession with Laura. He views himself as a rational actor despite his descent into homicidal ideation. By the end, his triumph turns to hollow despair as he realizes his actions have backfired, leaving him isolated and facing his own mortality.

Big Tim Austin serves as the foil to Nellon: he is physically imposing, optimistic, and genuinely fond of his companion. He is driven by a boyish sense of adventure and a desire to contribute to science, remaining entirely oblivious to Nellon’s malice. His gentle nature and curiosity eventually lead to his entrapment within the sphere, where he becomes a permanent, sleeping relic.

Laura exists primarily as a projection of Nellon’s desires. Though she is absent from the physical journey, her memory acts as the catalyst for Nellon’s moral decline. She is the prize Nellon believes he can win through violence, though she remains an unattainable, idealized figure that only serves to deepen his own self-deception.

In Its Own Voice

"I've got to kill you, Big Tim. I've just got to kill you! I want Laura--and you're standing in my way...."

Nellon struggles with his dark, singular intention while battling the harsh Titanian gale.

"If it wasn't for Tim, I'd never hesitate to marry you."

Nellon recalls the specific, painful memory of Laura’s rejection that anchors his obsession.

"Because when his batteries were exhausted, his suit would cool--and the storm would kill him."

In his final moments, Nellon realizes the cold reality of his fate as the realization of his long-term isolation sinks in.

What It's Really About

The story acts as a grim meditation on the corruption of the human spirit through obsession. The "Sphere of Sleep" serves as a literal and metaphorical device for escapism; it highlights the danger of replacing reality with a constructed, self-serving fantasy. The central argument is that the pursuit of a desired outcome through immoral means inevitably leads to a self-imposed prison. Ultimately, the book questions whether one can ever truly possess the object of their desire if the path to that possession requires the death or erasure of their own humanity.

Why Read It Today

This story offers a taut, atmospheric experience perfect for readers who enjoy classic mid-century science fiction. It feels like a tense, contained episode of The Twilight Zone, where the setting of Titan—a place of "glittering ice sheets" and "yawning chasms"—is used to amplify the internal psychological decay of its characters. Those who appreciate character-driven narratives that pivot on sudden, ironic reversals of fortune will find the conclusion particularly sharp.

Modern readers should be prepared for the mid-1940s prose style, which favors earnest, heavy-handed internal monologues and a somewhat traditional view of gender roles. The dialogue can feel a bit melodramatic, and the "he-man" tropes of the era are prominent. However, the pacing remains brisk, and the depiction of the vast, uncaring Titanian landscape is genuinely evocative. It is a story that lingers because of its central, haunting image: a man who, in his attempt to secure a future of happiness, inadvertently deletes himself from the world, leaving his rival to sleep peacefully in an alien tomb. It is a brisk, sobering read that manages to pack a significant amount of existential dread into its short length.
