Conan Doyle must have grown tired of his creature when he wrote The Valley of Fear. Fourth and last of Sherlock Holmes novels, only the first part is dedicated to Holmes while the second is the account of another, equally brilliant detective. The author's fascination for extraordinary men, heroes who devote themselves to justice, is showed once again in the character of John McCurdo, a killer and a criminal belonging to a lodge which is in reality a criminal organization. With a generous coup de théatre, the man reveals to be Birdy Edwans, none other than a Pinkerton detective infiltrated into the lodge in order to collect evidence and destroy its members. So this time Holmes' case is about another detective. But the latter, who has many of the qualities of S.H. himself, has to die and leave the original one to vigil upon his soul and seek revenge for his murder. Once again Moriarty's shadow casts upon the lives of noble men and corrodes the peace of the whole England, extending overseas its gloomy hand. The destiny of the world rests in the hands of two men, and it is a good vs bad battle all over again.
