The world holds too many secrets. From the foggy alleys of London to the frozen slopes of the Urals, from the silence of an airplane cabin to the secluded valleys of Norway, history is filled with mysteries that have never found an answer.

But one woman, known only by the initial “S”—her true identity concealed, her age guessed to be in her twenties—chooses to reopen the forgotten archives. With the persistence of an investigator and the courage of a truth-seeker, she steps into the world’s most infamous unsolved cases.

In every case, “S” does not simply examine documents and evidence; she dares to challenge history itself by offering possible solutions. At the end of each chapter, her findings are questioned once more—tested in interviews with real-world journalists, anchors, and public figures.

Is truth something that truly exists, or merely the version we choose to believe?
This novel presents 20 of the world’s greatest unsolved mysteries—and a fictional attempt to resolve them.

The Inquirer's Chronicle of 20 Eternal Secrets and Unsolved Crimes


The neon light in the archive room flickered, reluctant to shine upon the rows of dusty folders stacked on iron shelves. The air smelled of damp paper, carrying the weight of secrets waiting to be unearthed.


At the center of the room, a woman sat in silence. Strands of her hair fell across her face, but her eyes gleamed sharply as they scanned the faded folder before her. On its cover, written in black ink:


And many more, each one a dark shadow from a different corner of the world.


The woman was known only by a single letter: S.


Her age was estimated to be somewhere in her twenties, but no one truly knew. Her name, her past, even her ultimate purpose—hidden beneath the same fog that cloaked the mysteries she pursued.


Her fingers traced the fragile paper, as though absorbing the voices of the past. Then she wrote her first note with steady hand:


"If history refuses to answer, then let me be the one to write it."


Outside, the night wind whispered against the windowpanes. Inside, under the flickering light, S had just opened the first door of a long journey: a journey against time, against silence, and against the shadows that guard the truth.
