Mario Vargas Llosa immerges himself in the novel Les Miserables from the perspective of the avid reader, the enthusiastic one, the creator that knows how a great work is constructed; therefore finding the secret mechanisms that moved Victor Hugo's pen. This work is not a book about another book; instead, he reveals the keys with which the French narrator made his creation. He discovers the tracks that speak of a writer, a political man but above all, a human Victor Hugo; one who is just another character in the novel.
