Machado de Assis is perhaps the greatest Portuguese language romancist, and certainly the most important Brazilian author. This book is his best work. In a very short manner, it could be desribed as a "Brazilian Ottello", but it mustn't be be considered as a version of the Shakespeare classic, but a unique story, very reach in itself. Machado has an amazing ability to make the reader feel like his characters, and involves us in a tram where the complete uncertainty and blind jealousy is thrilling, and rises our deepest passionate feelings, for or against the main character. This book is a definitely a must read for everyone who enjoys good literature.
