Never meet again

In the quiet shadows of post‑war Berlin, an aging professor spends his days in a government lab while his evenings are devoted to a clandestine project that has consumed fifteen long years. He walks the bustling Unter den Linden, watching youthful couples drift past, his mind far away in a dim basement where a single light flickers over an apparatus that could open a one‑time exit from reality itself. The routine of cocoa, pastries, and brief lunches masks a relentless obsession, a secret that even his modest government pension can’t illuminate.

Now, with the final components in place, the scientist feels the weight of both his past accolades and the isolation of his hidden work. As spring warms the city, he stands on the brink of a decision that could alter the course of his life and perhaps the world, confronting the moral cost of a device that promises escape—once, and only once.
