The stories included in El hombre que sabía demasiado introduce us to Horne Fisher, an investigator who solves crimes not through his wits or deductive skills, but through his knowledge of the ins and outs of British politics and his intricate network of contacts. However, he is not the only peculiar character in this collection of stories that subvert the detective genre. This work is one of the best works by one of the great authors that English literature has produced.
