In a dark apartment, in an anonymous building in a generic city, hides a human figure built to perfection, who will inspire you to think, sweat, and explore the nature of man. Ostensibly, the character, a hard-working old man, is a failed, miserable person. Even the author does not feel sorry for him. Until, at an unexpected moment, one of those moves of imagination and invention that only wonderful literature can bring about, occurs, and everything is turned upside down… A person in an apartment, on a certain floor in a building: an entire world, a complex web of relationships, a paraphrase of our society. This is a book that begins as a social drama and turns into a fascinating thriller: a wealth of plots and subtleties, black humor, and above all, a lot of literature. Martin Cohen, with a rare mastery of the art of storytelling, establishes his place as one of the representatives of the golden age of contemporary Latin American literature. "A novella that is an extraordinary, suspenseful, and extreme test case of one character and her world inside an apartment" Edmundo Fez Soldan "Old age. Failure. Humanity and its reversal are imprisoned in a particularly pure and cunning work" Laura Lynn
