Don't Panic!

In Short

Robert W. Krepps's science fiction story follows the aftermath of a devastating alien invasion by the Graken, a bird-footed, one-eyed race from a distant galaxy that accidentally conquers Earth and plans to transport the planet across the cosmos. Sergeant Trace Roscoe rallies a cynical, disparate group of survivors to infiltrate an enemy ship, sabotage its controls, and defeat the alien threat. It has endured for its gritty depiction of human resilience, fast-paced pulp adventure, and the sharp, pragmatic voice of its hard-boiled protagonist.

The Story

The story opens on January 9, 1955, when green-skinned aliens launch a sudden, devastating attack on Earth, obliterating cities with all-destructive rays. Amid the smoking ruins, Sergeant Trace Roscoe revives from a seeming death, kills an alien invader, and sets out to build an army. He gathers a reluctant band of survivors from a basement: a grumpy man mourning his pet rabbit, a cynical big man named Hafnagel carrying a sharp-tongued woman named Barbara on his shoulders, a plump complainer named Kinkaid, a nervous blond man named Johnson, a midget named Slough, a magician named Bill Blacknight, and a schoolteacher named Jane Kelly.

Trace commands the bickering group across the icy landscape toward Washington, D.C., enforcing discipline through sheer force of will and a few well-placed slaps. They reach the aliens' headquarters town under cover of darkness, where the overconfident Graken keep no sentinels. Using a classic projection trick involving an old movie theater playing a German military film, they exploit the aliens' two-dimensional eyesight—which mistakes the screen's marching troops for literal giants—causing the invaders to panic and flee.

Captured by the aliens, Trace learns from an interrogated captive named Glodd that the Graken are overpopulated and use linked flying saucers to kidnap whole planets into their home star system, Lluagor. Realizing the Earth is about to be stolen away, Trace and Slough sneak back into a grounded saucer. Working under intense pressure, they successfully "gimmick" the ship's electronic controls and resonant cavity magnetrons to trigger a chain reaction.

As they flee into the ruins, the ring of alien saucers detonates and vaporizes entirely. In the aftermath, the group realizes they have saved the planet, though a lingering, chilling doubt remains over whether the explosion happened before or after they were pulled into the distant Lluagor system. Refusing to despair, Trace takes command of the survivors, determined to find other living souls, rebuild civilization, and patch the world back together.

How It Unfolds

• The invasion begins: Green-skinned extraterrestrials launch a sudden, devastating assault on Earth, reducing cities to stinking tombs and killing millions in a matter of minutes.
• The sergeant rises: Sergeant Trace Roscoe wakes up among the ruins, kills an alien in close combat, and resolves to hunt down the opposition by gathering a squad of survivors.
• The reluctant recruits: Trace collects an eccentric group from a cellar, including a grieving pet owner, a bickering couple, a cowardly plump man, a magician, and a schoolteacher.
• The march to Washington: Battling both harsh winter weather and his own insubordinate recruits, Trace drives the group toward the capital to locate the alien fleet.
• The theater trap: The survivors hide in a small town's abandoned theater, where projecting a roaring German military film tricks the aliens into fleeing from imagined giants.
• The captive's secret: An interrogated alien prisoner reveals the Graken's plan to use linked flying saucers to kidnap Earth into their home star system, Lluagor.
• Sabotaging the saucer: Trace and the midget engineer Slough sneak into an enemy ship, locate its complex electronic magnetrons, and rewire the controls to overload.
• The planetary explosion: The altered saucers detonate and atomize completely, leaving the survivors to wonder if they saved Earth or if they were already dragged across the cosmos.

The People

• Trace Roscoe: A tough, level-headed Irish sergeant who takes command of the apocalypse. He wants to fight the enemy to his last breath, overcomes stubborn resistance from his crew, and ends up a respected leader who earns the affection of Jane Kelly.
• Slough: A tiny midget engineer who reads science fiction and possesses incredible technical knowledge. He wants to help defeat the invaders, assists Trace with repairing and rewiring the alien saucer, and reveals a mysterious, rapid healing ability that leaves his companions stunned.
• Jane Kelly: A sensible, clear-eyed schoolteacher. She faces the horrors of the invasion with quiet bravery, supports Trace's mission without complaint, and ultimately shares a tender bond with the sergeant as they prepare to rebuild the world.
• Hafnagel: A large, cynical man who initially fights Trace's authority and wants to scavenge the ruins. He carries Barbara on his shoulders, eventually realizes he cannot take the destruction lying down, and returns to join the final fight.
• Barbara Skye: A sharp-tongued, resilient woman who refuses to be left behind. She clings to Trace's uniform for a sense of security and travels across the frozen landscape on Hafnagel's shoulders.

In Its Own Voice

January 9th, 1955 began like any normal day on Earth.

This opening line establishes the abrupt, ordinary-turned-apocalyptic tone of the narrative right as the invasion strikes.

A sergeant whose army was gone had to find himself another in a hurry; and if so be it he was the general in that one, well, Trace Roscoe was ready to take on the job.

This sentence highlights Trace's pragmatic, take-charge military attitude amidst total global annihilation.

"The aliens are invincible; but a man might avoid them for years in the hills."

Johnson's defeated declaration underscores the initial despair and hopelessness shared by the civilian survivors before Trace whips them into shape.

What It's Really About

The story explores the limits of human endurance, agency, and adaptation when facing insurmountable odds. Krepps questions what remains of humanity when civilization is instantly wiped out, contrasting the cowardly impulse to hide with the stubborn, irrational need to strike back. The narrative suggests that survival is not merely a matter of physical strength, but of psychological resilience and leadership. Furthermore, it plays with the idea of perspective and perception—both literally, through the aliens' fatal lack of depth-perception and vulnerability to optical illusions, and figuratively, through how ordinary people rise above their flaws to become heroes when everything is lost.

Why Read It Today

Readers who love classic mid-century pulp science fiction, gritty military survival stories, and hard-boiled protagonists will thoroughly enjoy this novella. Reading it feels like stepping directly into a brisk, atmospheric 1950s magazine adventure, complete with frozen landscapes, snappy dialogue, and high-stakes techno-thriller improvisation. Modern readers should be prepared for some dated period attitudes, colloquial language, and a distinctly blunt, chauvinistic edge to the protagonist's interactions with his female companions. Yet, beneath the rough exterior lies a deeply satisfying, fast-moving narrative about ordinary people finding purpose in the ashes of the world. What stays with you is the stubborn, dust-off-your-knees optimism of the final march—four battered humans walking into an uncertain sky, ready to police up a broken planet.
