Una fa?bula moral con trazas detectivescas y cienti?ficas que indaga en el amor y la infidelidad. Una novela ero?tica y negra que explora las formas que adoptan las mentiras. Alrededor de la mitad de los seres humanos confiesa ser infiel sexualmente a su pareja. ¿Pero la otra mitad dice la verdad o miente? Solo hay una forma de comprobarlo: investigar su vida a trave?s de detectives o de medios de espionaje electro?nico. Este es el experimento antropolo?gico que plantea esta novela: investigar sin su consentimiento a seis mil personas para elaborar por fin una estadi?stica fiable de los comportamientos sexuales de nuestras sociedades. Irene, su protagonista, busca en la sexualidad los secretos del alma humana. De joven, viaja de Madrid a Chicago para realizar sus estudios universitarios en Psicologi?a, y alli?, lejos de su familia, empieza a analizar casi cienti?ficamente a los hombres con los que se cruza y con los que se acuesta. Su mirada fri?a de investigadora cambia cuando se enamora del argentino Claudio, que arrastra consigo un doloroso secreto y cuya familia tiene un pasado oscuro vinculado con la historia de su pai?s. Cien noches es a la vez una novela de reflexio?n sentimental, de indagacio?n ero?tica y de persecucio?n policial de un asesino que no ha dejado ningu?n rastro de su crimen. En Cien noches se exploran las distintas formas de amor -algunas radicales y extremas- y los diversos comportamientos sexuales -algunos igualmente radicales y extremos-; se levanta acta de la lealtad, la infidelidad, los deseos inconfesables, los tabu?s, las medias verdades y los engan?os que envuelven nuestras relaciones. Se habla de ma?scaras y de mentiras. Y a modo de juego se incorporan una serie de expedientes de adulterios que el autor pidio? a los escritores Edurne Portela, Manuel Vilas, Sergio del Molino, Lara Moreno y Jose? Ovejero, en un estimulante ejercicio de promiscuidad literaria. A moral fable with detective and scientific traces that investigates love and infidelity. An erotic and black novel that explores the forms that lies take. About half of human beings confess to being sexually unfaithful to their partner. But does the other half tell the truth or lie? There is only one way to prove it: to investigate his life through detectives or electronic means of espionage. This is the anthropological experiment that this novel proposes: to investigate without their consent six thousand people to finally elaborate a reliable statistic of the sexual behaviors of our societies. Irene, the protagonist of it, seeks in sexuality the secrets of the human soul. As a young woman, she travels from Madrid to Chicago to do her university studies in psychology, and there, far from her family, she begins to almost scientifically analyze the men she crosses paths with and with whom she sleeps. Her cold investigative gaze changes when she falls in love with the Argentine Claudio, who carries a painful secret with him and whose family has a dark past linked to the history of her country. One Hundred Nights is at the same time a novel of sentimental reflection, erotic investigation and police pursuit of a murderer who has not left any trace of his crime. In One Hundred Nights the different forms of love - some radical and extreme - and the various sexual behaviors - some equally radical and extreme - are explored; A record of loyalty, infidelity, unspeakable desires, taboos, half-truths and deceptions that surround our relationships are drawn up. There is talk of masks and lies. And as a game, a series of adultery files are incorporated that the author requested from the writers Edurne Portela, Manuel Vilas, Sergio del Molino, Lara Moreno and Jose? Ovejero, in a stimulating exercise of literary promiscuity.
