Never meet again

In Short

This science fiction story follows Professor Kempfer, a physicist who spends fifteen years in the Berlin of a victorious Nazi Germany building a machine to escape his hollow life. Upon activating it, he crosses the multiverse into a bleak, Soviet-occupied Berlin. What begins as a desperate search for personal freedom quickly devolves into a nightmare of bureaucratic control. By exploring the futility of individual resistance against monolithic states, the work has endured as a haunting study of how history’s shifting tides can render human suffering both tragic and disposable.

The Story

In 1958, Professor Kempfer exists in a Berlin that won the Second World War. His life is a mask of compliance; he accepts a sinecure from the Reich while spending every spare moment in a basement laboratory. He is haunted by the death of his wife, Marthe, whom the state allowed to perish from illness despite his service. After years of isolation, he completes a device capable of shifting his atomic vibration into an alternate reality. He triggers the machine, leaving his old life to burn behind him, and arrives in a vastly different Berlin—a gray, impoverished city divided by Cold War tensions.

This new world is a shock. He finds a reality where Germany lost the war, leaving the city in ruins, occupied by Soviet forces, and filled with a populace hardened by defeat. As he wanders, cold and disoriented, he is suddenly reunited with a version of Marthe. She is alive, though weathered by decades of loss and the grief of believing him dead in an Allied bombing raid. They cling to one another, but their reunion is short-lived. Marthe, now a loyal functionary for the People’s Government, has already alerted her superiors to his arrival.

The state moves quickly. Colonel Lubintsev, a Soviet advisor, arrives to inform Kempfer that his arrival is no mystery; they have a complete dossier on his counterpart and intended to recruit him all along. They view his technology as a strategic asset, a way to plunder resources from other dimensions and unleash devastation on their enemies. When Kempfer protests, Marthe, now completely conditioned by her own harsh reality, insists he cooperate for their "shared future." She is unable to process the existence of a "new" Kempfer without invalidating the years of mourning she has invested in the old one.

The final betrayal comes when the state introduces him to his new project lead. It is Georg Tanzler, the same man who was his colleague in the other world. Tanzler is eager to exploit Kempfer’s genius for the new regime, oblivious to the existential horror of his friend’s situation. Kempfer, physically and emotionally shattered by his journey and the realization that there is no escape from the machinery of the state, lies in bed, unable to lift his hand. He acknowledges that he is "going away again," a final, quiet resignation as he realizes that in every possible world, the state will find a way to claim him.

How It Unfolds

The secret project Professor Kempfer toils for years in a government laboratory, hiding his true work beneath a facade of aging compliance. He reflects on his loss and the emptiness of the Reich’s "thousand-year" peace.

The jump Pursued by his colleague Tanzler and the suspicion of the state, Kempfer rushes to his basement. He activates his device, triggering a violent shift that leaves his old life in flames.

A gray arrival He emerges into a shattered, Soviet-occupied Berlin, finding a world he does not recognize. He attempts to navigate the grim, hostile streets but finds himself trapped by checkpoints and suspicion.

The unexpected reunion Near collapse, Kempfer encounters a version of his deceased wife, Marthe. Their joy at meeting is immediately compromised by the realities of her life under the new regime.

The state’s trap Colonel Lubintsev reveals that the state has been waiting for his arrival. Kempfer is informed that he will be put to work, with Marthe acting as both his companion and his warden.

The final surrender Tanzler appears to oversee the project, completing the cycle of entrapment. Kempfer, having lost all hope of autonomy, collapses under the weight of his own creation.

The People

Professor Kempfer is a man whose intellect is his only armor, yet his deep grief for his wife makes him vulnerable. He wants nothing more than to escape the shadow of the state, but he lacks the ruthless malice required to truly defeat it. Marthe is a woman defined by her trauma; in this world, she has survived by adopting the rigid pragmatism of the regime. She views Kempfer not as her husband, but as a potential source of stability, unwilling to sacrifice her long-held grief for a man who defies her reality. Colonel Lubintsev represents the cold efficiency of the state. He is charming, bureaucratic, and utterly predatory, viewing human beings only as variables to be integrated into the state’s agenda. Finally, Georg Tanzler serves as the persistent echo of Kempfer’s past; he is a man of "good humor" who is nonetheless an agent of the same forces that destroy Kempfer’s spirit, regardless of which side of the war he serves.

In Its Own Voice

"He had spent fifteen patient years of painstaking work, all to construct an exit--which could be used only once!"

This initial description of Kempfer's machine highlights the desperation of a man who has sacrificed his entire life to secure a single, final opportunity for escape.

"I have become a cave-dweller! he thought with sudden realization."

Kempfer reflects on the way his secret work forced him to disconnect from the passage of time and the life of his city.

"I am going to go away."

During a tense confrontation with his colleague, Kempfer reveals his secret intention to abandon the Reich, signaling the beginning of his final, doomed flight.

What It's Really About

The book explores the concept of the "total state"—whether fascist or communist—and its insatiable need to colonize the individual. Kempfer’s tragedy is not just that he is caught, but that he realizes his own scientific labor provides the tools for his own imprisonment. The narrative argues that under a system that demands total ideological and intellectual submission, the "truth" of a person's identity is secondary to their utility. Even when Kempfer manages to transcend the physical boundaries of his world, he finds that the structures of power remain identical. The story asks a chilling question: if one can jump between infinite realities, what does it mean to be free if the institutions of control are a universal constant?

Why Read It Today

Readers who appreciate mid-century science fiction that prioritizes character psychology over technical spectacle will find much to admire here. The writing is precise and melancholic, capturing the claustrophobia of a man living in a world that feels wrong in every fiber of its being. It evokes a specific, heavy atmosphere of the early Cold War—the smell of ozone, the damp of cellars, and the constant, low-level dread of living under surveillance.

However, readers should be prepared for the book's pacing, which is deliberate and focused almost entirely on the protagonist’s internal state. It is not an action-heavy adventure; it is a slow-motion collapse. The period attitudes—particularly the way the narrative treats the characters' gender roles and the era's specific, binary vision of the world—reflect the time of its original publication. It does not offer a triumphant ending or a hopeful resolution, but rather a somber, lingering look at the cost of survival. It stays with you precisely because it denies the reader the satisfaction of an escape, forcing you to sit with the realization that for Kempfer, there is no corner of the multiverse where the state does not reach.
