The Space Flame

In Short

This tense science-fiction tale centers on the crew of the Denebola, a survey ship returning from the asteroid belt. As monotony and fear take hold, the crew descends into madness, fueled by the appearance of "flame-things"—enigmatic, colorful entities that consume metal and discharge paralyzing rays. The story documents the desperate survival of the ship’s officers as they navigate internal treachery and the external threat of a species that turns their own ship into a death trap, eventually finding salvation in an unlikely, accidental discovery.

The Story

The Denebola returns from a long, grueling three-year surveying expedition, its crew frayed by isolation and the inexplicable hostility of a malfunctioning rocket jet. Tensions spike when a crew member named Kalson is found murdered; suspicion falls on Wrymore, though Captain Wallace lacks the evidence to confine him. Soon, the ship’s atmosphere grows heavy with dread as crew members report seeing spectral, flame-like entities that pulse with shifting, brilliant colors. These "flame-things" begin corroding the ship’s hull, leaving behind only hydrogen gas and ruin.

As the crew’s collective sanity fractures, the pent-up tension explodes into open mutiny. Led by the desperate and delusional, the crew attempts to seize control. Second officer Cargyle fights a tactical retreat through the ship’s secret maintenance passages, where he encounters one of the alien entities. It is a sentient, writhing mosaic of light that proves immune to his blastor pistol. When it turns a blinding, agonizing ray upon him, he survives only by the grace of his comrades, who discover him unconscious and revive him with emergency oxygen.

The mutiny ends in catastrophe: the rebels abandon the ship in scout rockets, doomed by limited supplies, while the officers remain trapped on the derelict Denebola. The flame-things continue to multiply, consuming the ship’s metal skeleton. The astrophysicist, Markoe, theorizes that these beings are creatures of pure energy that feed on the heavy atoms of the ship’s hull. He realizes that calling for rescue would be a death sentence, as the entities would inevitably hitch a ride on any responding vessel, threatening to spread their destructive hunger to the planets of the solar system. Bound by the "spaceman’s oath" to prevent the spread of such a plague, the officers resolve to face their demise rather than risk civilization.

In the final hours, a glimmer of hope emerges. Parker, a crewman who has obsessively tinkered with a broken rocket timer throughout the crisis, accidentally creates a field of electrical interference. Cargyle observes that the flame-things recoil and disintegrate in the presence of this specific, sparking frequency. Realizing that the timer’s erratic output is the key, the crew amplifies the field. The entities are destroyed, the Denebola is saved from total disintegration, and the crew finally manages to signal the outpost at Tracolatown. Help arrives, and the survivors are rescued, their duty to the system fulfilled at a terrible cost to their ship and their own nerves.

How It Unfolds

The voyage begins The Denebola returns from a three-year mission in the asteroid belt, carrying a crew on the brink of collapse. Internal feuds and equipment failures create an atmosphere of paranoia that Captain Wallace struggles to suppress.

The haunting Reports of ghost-like, multi-colored flames appearing in the ship's corridors spread panic among the men. These entities begin physically damaging the vessel, manifesting as a mysterious, corrosive force that no one can explain.

Mutiny erupts The psychological strain leads to a violent uprising, with the crew turning against the officers. Cargyle leads a desperate defense, eventually retreating into the secret guts of the ship where he first confronts the alien threat.

A stand against extinction Trapped on a dying ship, the officers weigh their own survival against the potential destruction of Mars and Earth. Markoe identifies the flame-things as energy-based predators and argues that the ship must not be rescued.

The accidental cure While the crew waits for the end, Parker’s stubborn efforts to repair a faulty rocket timer inadvertently reveal the creatures' weakness. The resulting frequency destroys the flame-things, allowing the crew to finally signal for help.

The People

Captain Wallace acts as the steady, iron-willed anchor of the Denebola. He is an old-guard officer who values duty and the safety of the solar system above his own life. His sternness keeps the bridge together, but he is forced to make the harrowing decision to prioritize the safety of Earth over the lives of his mutinous crew.

Cargyle, the second officer, provides the physical agency of the story. He is a pragmatic man of action who survives a direct encounter with the alien entities. His survival allows him to piece together the truth about the flame-things, and his presence of mind during the final chaos proves vital.

Markoe is the ship’s astrophysicist, tasked with understanding the inexplicable. He brings scientific gravity to the crisis, identifying the "earthworms of space" as a cosmic threat. He is the moral compass who insists that the crew must not return to port if they carry a contagion, forcing the others to accept a potentially fatal sacrifice.

Parker is the unassuming crewman whose obsessive focus on a broken machine inadvertently saves the ship. Unlike the rest of the crew, who succumb to the "space-crazy" atmosphere, he channels his anxiety into mechanical work, proving that in the vacuum of space, practical skill can outweigh grand theories.

In Its Own Voice

"Flame that hissed and coiled and struck with jeweled tongues of Death."

The narrator describes the terrifying, unnatural nature of the entities that haunt the ship.

"Loneliness and monotony change men queerly, undermine character and sanity."

This serves as the overarching explanation for why the crew eventually turns against their officers.

"The thing lay flat, pulsing slowly with a gorgeous display of color."

Cargyle encounters an entity in the maintenance passage and observes the beautiful yet threatening nature of its movement.

What It's Really About

The central theme is the psychological toll of deep-space isolation, which serves as a catalyst for both human depravity and heroic sacrifice. The book argues that duty is not merely a set of rules but a burden that requires a "spaceman" to choose the survival of the collective over the individual. It contrasts the fragility of the human mind—prone to the madness of "space-craziness"—with the cold, mechanical logic of the universe, where life, even in the form of energy-based "earthworms," is defined by a relentless, indifferent drive to consume.

Why Read It Today

Readers who enjoy classic, pulp-era science fiction will find this a quintessential example of the 1940s aesthetic: high-stakes peril, a grim sense of professional duty, and a "mad scientist" problem-solving plot. The writing is punchy and moves with a frantic, claustrophobic energy that mirrors the state of the crew.

However, readers should be prepared for the limitations of the era. The characterizations are brief and archetypal, focusing more on the immediate survival crisis than on deep character development. The dialogue occasionally leans into the dramatic, "space-crazy" vernacular of the period, which may strike a modern reader as stilted. The book does not dwell on the technical details of its setting, opting instead to maintain a high level of tension from the opening pages to the final, desperate rescue. It is a quick, atmospheric read that captures a specific moment in the evolution of science fiction, where the vast, cold reaches of space were seen as a source of both physical danger and profound psychological pressure. It will stay with you primarily for the vivid, colorful imagery of the "flame-things" and the grim, unwavering resolve of the officers as they face an impossible choice.
