Young inventor Larry Powell faces a grueling race against time to rescue his fiancée, Joan, from a nightmarish, parallel dimension inhabited by predatory rat-men and lethal, crystalline entities.
In Short
This novella is a classic of early twentieth-century science fiction, centering on a desperate cross-dimensional rescue mission. When a teleportation experiment goes awry, leaving the intrepid Joan Marlowe trapped in the alien world of Arret, her fiancé and uncle must race to repair their mechanism before an atomic time limit makes her exile permanent. The story endures as a quintessential example of "pulp" fiction, combining high-stakes action, bizarre biological concepts, and the sheer thrill of scientific discovery. It is a brisk, imaginative plunge into a world where the laws of physics are inverted and danger lurks in every shadow.
The Story
The story begins in a laboratory where Benjamin Marlowe and his assistant, Larry Powell, discover that Joan has impulsively teleported herself to Arret, a parallel Earth where atomic charges are reversed. The experiment fails when the projector’s coils fuse, leaving Joan marooned. The men realize that if she is not recalled within twelve hours, her atoms will permanently stabilize in the Arretian plane, effectively erasing her from existence. As they frantically repair the equipment, they recover a solidified "amber egg" containing an alien skeleton and Joan’s belt, which suggests she has been captured.
Determined to save her, Larry uses the repaired projector to travel to Arret, arriving in a landscape of red vegetation under a blood-red moon. He quickly learns the environment is hostile; he encounters the "Tinkling Death," a phenomenon where giant, semi-transparent crystals lure and consume living creatures, encasing their remains in crystalline shells. After narrowly escaping an octopus-like bat creature, Larry is captured by a horde of rat-men—humanoid rodents with primitive tribal instincts. He is dragged to their subterranean lair, the Cave of Blue Flames, where he finds Joan imprisoned in a pit.
The rat-men hold the couple captive for a ritual sacrifice to the Devil Crystals. As the twelve-hour deadline approaches, the rat-men force the prisoners toward a pit where the giant, carnivorous crystals wait. Joan and Larry realize their only hope is to steal back their Silver Belts—the devices that enable teleportation—from the rat-king. During the ceremony, they feign the effects of a paralytic drug given to them by their captors, then launch a surprise attack. They seize the belts and engage in a desperate firefight as the rocky ledge beneath them collapses, dropping them into the pit with the hungry crystals. Just as the crystals’ lethal, glass-like filaments begin to bind Larry, the recall wave initiated by Benjamin Marlowe hits. The world of Arret dissolves into a swirling vortex of roseate flame, and the couple is safely rematerialized on the laboratory floor, narrowly escaping the crystalline doom.
How It Unfolds
The lab disaster Joan Marlowe initiates a solo voyage to Arret, only for the atomic projector to suffer a catastrophic mechanical failure. The resulting breakdown leaves the scientists with a strict twelve-hour window to rescue her before she is permanently trapped in the alternate reality.
The amber discovery The men successfully retrieve an object from Arret that initially appears to be a tomb for Joan, containing a strange, skeletal creature. Upon shattering the crystalline shell, they find a desperate note from Joan, confirming she is alive and held captive in a cavern.
The red world Larry travels to Arret and finds a surreal, monochromatic landscape dominated by crimson vegetation and a blood-red moon. He discovers that the "Tinkling Death"—the sound of shattering glass—heralds the presence of giant, predatory crystals.
The rat-men’s lair Larry is overwhelmed by a vast horde of rat-men, described as beastly humanoids with rodent-like features. He is taken to the Cave of Blue Flames and reunited with Joan in a pit designed to serve as a feeding ground for the crystals.
The final stand Facing immediate sacrifice, the couple uses a faked drug-induced stupor to ambush the rat-king and recover their teleportation belts. A chaotic battle ensues as the ground collapses, forcing them into a final confrontation with the crystalline entities.
The narrow escape As the crystals prepare to consume them, the recall signal from Earth reaches across the dimensions. The reality of Arret is pulled away from the couple, returning them safely to the comfort of their home laboratory.
The People
Larry Powell is the story's action-oriented hero. Driven by his love for Joan and a sense of scientific duty, he transforms from a cautious laboratory assistant into a resourceful combatant. His tactical thinking during the rat-men’s ritual is what ultimately secures their survival.
Joan Marlowe is defined by her curiosity and courage. Rather than waiting for the men to perfect their technology, she takes the initiative to explore Arret, despite the risks. Even while imprisoned, she remains observant, leaving a note for her rescuers and maintaining her composure until Larry arrives.
Benjamin Marlowe is the elder scientist whose anxiety mirrors the reader's own. He provides the technical expertise and the essential recall mechanism. His character represents the weight of responsibility; he bears the guilt of the initial accident and carries the burden of the final, risky attempt to bring the pair home.
The rat-king acts as the primary antagonist, a grotesque, primitive leader who values the Silver Belts as shiny trinkets. His horde provides a relentless, overwhelming threat that forces the protagonists to use every bit of their ingenuity to survive.
In Its Own Voice
The prose captures the eerie, heightened atmosphere of the parallel world:
"The crystalline song swelled to a crescendo climax." This occurs when Larry first encounters the sound of the predatory Devil Crystals.
"High in the reddish-saffron sky overhead there blazed a lurid orb of blood-red hue, the intense heat of its ruddy radiance giving the still dry air a nearly tropical temperature." Larry describes his first impressions of the alien environment upon his arrival in Arret.
"The things were giant living crystals--great silvery semi-transparent shapes nearly ten feet in height, their faceted sides pulsing in sinister and incredible life as they gleamed in unearthly beauty beneath the blazing rays of the red moon!" This observation captures the terrifying, mesmerizing appearance of the creatures that threaten to consume the protagonists.
What It's Really About
At its heart, this is a story about the fragility of human existence when confronted with forces beyond our comprehension. The "Devil Crystals" represent an incomprehensible, alien intelligence—one that does not hate humans but simply views them as food. The narrative argues that curiosity is both a vital engine for progress and a dangerous impulse that can lead to total isolation. By placing the characters in a world that occupies the same space as Earth but operates on inverted physics, the book explores the thin line between reality and the unknown. It asks whether humanity's technological mastery is sufficient to protect us when we step outside the familiar boundaries of our own dimension.
Why Read It Today
Readers who enjoy the brisk, high-stakes pacing of classic pulp science fiction will find much to admire here. It possesses the quintessential "Golden Age" feel: inventive, rapid-fire, and unburdened by lengthy expositions. It is a story designed to be consumed in a single sitting, prioritizing the thrill of the "what if" over deep character analysis.
However, readers should be prepared for the stylistic conventions of its era. The dialogue is often utilitarian, serving to move the plot from one action sequence to the next, and the descriptive language leans heavily into the dramatic and the macabre. The portrayal of the "rat-men" as a low-evolutionary, primitive horde reflects the period’s sometimes blunt attitudes toward "savage" antagonists, which modern readers will recognize as a common trope of 1930s adventure fiction. If you can appreciate the work as a time capsule of early science fiction—where atomic theory was often a magical plot device and danger was always just one pulse of a ray-gun away—you will find it a compelling and imaginative read. What stays with you long after the final page is the striking, auditory imagery of the "tinkling death" and the genuine sense of relief when the cold, red world of Arret finally gives way to the familiar, safe glow of the lab.
