The Valley of Fear and Selected Stories (Classic, Modern, Penguin)

Holmes has been summoned by a coded message to the house of a man called Douglas. But he and Watson arrive to find they are too late - Douglas has been murdered, with a mysterious calling card left by his side. Scotland Yard is stumped, but Holmes, detecting the diabolical workings of his arch-enemy Moriarty, has some ideas of his own. In this compelling selection of tales, The Valley of Fear is accompanied by ten of the great detective's most curious cases, including The Six Napoleons, in which the statues of the Emperor are smashed to pieces; Charles Augustus Milverton, which features an evil blackmailer; and His Last Bow, in which Holmes is called out of retirement on a matter of national importance.
