Vogelstein is a loner who has always lived among books. Suddenly, fate grabs hold of his insignificant life and carries him off to Buenos Aires, to a conference on Edgar Allan Poe, the inventor of the modern detective story. There Vogelstein meets his idol, Jorge Lu-s Borges, and for reasons that a mere passion for literature cannot explain, he finds himself at the centre of a murder investigation that involves arcane demons, the mysteries of the Kabbala, the possible destruction of the world, and the Elizabethan magus John Dee"s "Eternal Orang-utan", which would end up by writing all the known books in the cosmos. Verissimo"s small masterpiece is at once a witty literary tour de force and a brilliant mystery novel in its own right.
