Zehru of Xollar

In Short

Hal K. Wells’s science fiction tale follows athletic tackle Robert Blake, his fiancée Helen Lawton, and a petty East Side mobster named Gil Mapes after an alien force net snatches them from a subway platform. Transported across universes to the planet Xollar, they land in an oxygenated containment cell constructed by Zehru, a rogue scientist fleeing a death sentence. Zehru intends to swap his consciousness into an Earthling's body to escape his executioners and conquer Earth. High-octane pulp pacing, bizarre alien biology, and relentless inter-dimensional peril keep this classic adventure moving.

The Story

Waiting for an uptown express train after midnight, former college football star Robert Blake and his fiancée Helen Lawton notice a heavy-set gangster, Gil Mapes, across the subway tracks. Suddenly, a deafening vibration of low-frequency infra-bass fills the station. Ribbons of green flame form a solid net around all three humans, lifting them out of Manhattan, through multi-dimensional space, and depositing them on a alien world beneath twin purple suns.

They materialize inside a large, oxygen-filled enclosure built to shield them from Xollar’s lethal purple atmosphere. Soon after their arrival, the green energy beam fires again, dumping a second batch of captives into the compound: a horde of headless, ape-like creatures from the star Vega. Guided telepathically by gelatinous gray egg-masses acting as collective brains, the creatures charge the humans. Armed with a heavy wooden branch and Mapes's fallen revolver, Blake discovers that shooting the central jelly masses instantly kills the associated ape-beasts. The remaining creatures panic and flee through the force field, where Xollar’s atmosphere rapidly dissolves them into purple slime.

Before the survivors can recover, a ray of red light paralyzes them. When Blake, Helen, and Mapes awaken, they find themselves immobilized under an overhead metal plate, facing their captor: Zehru, a scaly, tentacled scientist from Xollar. Zehru explains telepathically that he has been condemned to death by Xollar's ruling Council of Three. To escape, he built an inter-dimensional arch-gate to Earth. However, because his native body cannot survive in Earth's atmosphere, he plans to transfer his consciousness into one of the male captives before destroying the evidence.

Examining his prisoners, Zehru unknowingly places Blake's feet onto his rubberized topcoat. The rubber insulates Blake from the paralyzing charge, restoring his mobility. Faking paralysis until Zehru reaches for him, Blake grabs the alien's tentacles and hauls him through the force field into the enclosure. The collision wrecks the paralyzing disk, freeing Helen and Mapes.

Mapes immediately betrays his companions, sprinting toward the silver arch-gate to escape alone. Seeing the traitor, Zehru draws a tube-weapon and incinerates the mobster. Blake knocks the weapon away and battles the scientist hand-to-hand. The enclosure's oxygen acts as a deadly poison to Zehru, causing his scaly skin to melt. In his death throes, Zehru rips apart a power cable, causing the barrier walls to collapse and letting the deadly purple mists flood in.

With their lungs burning and the mists tearing at their bodies, Blake carries Helen toward the silver arch. Reaching the platform with his last bit of strength, Blake pulls the activation lever. The inter-dimensional force catapults them back across space, depositing them safely in Manhattan's Central Park at dawn as Zehru's distant apparatus explodes behind them.

How It Unfolds

Snatched from the subway A low-frequency vibration shakes a late-night subway platform before a glowing net of green flame traps Blake, Helen, and Mapes. The energy grid carries them away from Earth into an alien universe.

The battle with the Vegans Waking in an oxygenated cell under twin purple suns, the captives are attacked by a swarm of headless ape-like creatures. Blake discovers the beasts are controlled by a gelatinous central brain and uses Mapes's gun to destroy them.

The alien's plot exposed Paralyzed by a red ray, the captives meet Zehru, a tentacled scientist fleeing a death sentence. He reveals his plan to mind-swap into an Earthling body, walk through an inter-dimensional arch-gate, and dominate Earth.

Breaking the paralysis When Zehru shifts Blake onto a rubberized coat, the insulation breaks the paralyzing circuit. Blake pretends to remain trapped until he can drag Zehru into the cell, destroying the control apparatus.

Race for the arch-gate Mapes tries to desert the group, but Zehru disintegrates him with a ray gun. Blake overpowers the scientist, whose body melts in the oxygen-rich air, but the dying alien severs a cable that collapses the protective atmosphere walls.

Return to Central Park As purple gas invades the compound, Blake carries Helen through the suffocating air to the silver arch-gate. He pulls the lever just in time, sending them safely back to New York City at sunrise.

The People

• Robert Blake: An All-Western college football tackle whose physical strength, quick thinking, and protective instincts drive the group's survival. He figures out how to defeat the Vegans and uses his rubberized coat to escape alien paralysis.

What It's Really About

The story centers on humanity's endurance and adaptability when pitted against superior alien intellect and technology. It contrasts the cold, calculated logic of Zehru—who views other living beings purely as tools or disposable vehicles—with the instinctual loyalty and physical courage of the human characters. The narrative explores how crisis reveals true character, contrasting Blake's selfless drive to protect Helen with Mapes's self-serving betrayal. On a broader level, the plot reflects early science fiction's fascination with dimensional travel, showcasing how intelligence can take terrifyingly unfamiliar shapes across the universe.

Why Read It Today

Fans of mid-century pulp science fiction and cosmic adventure will enjoy this fast-paced tale. It moves at a breakneck speed, delivering classic tropes—alien mind-transfers, inter-dimensional travel, weird planetary environments, and high-stakes combat—without getting bogged down in slow exposition. The narrative carries a kinetic energy that captures the sensational flavor of 1930s magazine fiction.

The dialogue from the criminal character reflects period-specific slang that reads as distinctly dated today. Despite these stylistic relics, the core story remains an entertaining, quick read that offers an enjoyable glimpse into early space-age adventure writing.
