Dr. Valeria Molina is a neuropsychologist at the forefront of “shared memory” therapy—a daring protocol that combines high-resolution functional MRI, targeted transcranial magnetic stimulation, and AI-guided hypnosis to transfer fragments of memories between brains. Early clinical successes promised a revolution in treating trauma and amnesia… until “Patient 47,” Martín Rosales, began to relive visions of a forgotten massacre.

Under hypnosis, Martín describes a metal corridor, a relentless mechanical hum, dark puddles and four bodies lying face-down in high-visibility vests—details matching an official “accidental fire” that closed the case of missing factory workers years ago. Driven by an ethical obligation to justice, Valeria analyzes neural activation maps from other volunteers and uncovers a chilling convergence: identical memory traces appearing in multiple, unrelated brains—a “primeval memory” deliberately buried.

Determined to expose the institutional cover-up, Valeria teams up with Detective Javier Araúz. Together they reopen the archives, unearth dried bloodstains, charred bone fragments and a distinctive shoeprint implicating a high-ranking officer. Along the way they confront classified reports, manipulated witness statements, and a pact of silence reaching into the highest levels of police and prosecution.

Yet the very technique that unravels the crime tests Valeria’s own moral boundaries. Offers of academic fame, multimillion-dollar corporate funding and institutional pressure threaten to corrupt her mission. When her trusted lab partner is revealed as a traitor—leaking sensitive data to the conspirators—Valeria faces a harrowing choice: protect her career or put everything on the line to defend the truth.

The Trace of Lost Memory is a breakneck thriller where science and justice collide in a labyrinth of neurons and corruption. Through clinical sessions, forensic investigations and courtroom showdowns, Martín Fernández probes the limits of therapeutic confidentiality, the social responsibility of science, and our profound need to reclaim the memories of those who can no longer speak for themselves. Join Valeria Molina on a pulse-pounding descent into the darkest corners of the human mind—and an unyielding quest to harvest justice from the ruins of forgotten lives.
