A story of mystery and tension that captivated even José María Pemán, who, after being fascinated by his reading, interceded for its publication despite not winning the Blasco Ibáñez prize. A fast-paced novel with a relentless rhythm, it begins with a scene that shocks the reader: at dawn, a middle-aged writer hears a dull noise. Outside his window, a young neighbor has fallen, naked, from the sixth floor. The official version speaks of suicide, but neighborhood rumors and his own intuition awaken in the protagonist an obsessive need to know the truth. Thus begins an investigation that draws him into a world of desire, jealousy, secrets, and betrayal. A dark plot that combines the narrator's introspection with pure suspense. Set in the turbulent Pamplona of the Civil War, it portrays a universe where everyday life and historical tragedy are masterfully intertwined. The setting, full of precision and lyricism, makes each page an unforgettable testimony to a crucial era. Rediscovered today, this novel by Manuel Iribarren shows us a narrator capable of capturing the essence of the human soul in its darkest moments. These pages are much more than a story of intrigue: they are a literary classic that continues to pack a punch, inviting us to confront our own shadows. Each chapter opens with an original illustration, and the digital edition, annotated by a professor at the University of Navarra, allows for an enriched reading of this classic waiting to be rediscovered. "Iribarren is the great writer of Pamplona. With this novel, I have spent a few magnificent hours reading." José María Pemán
