Volume I includes the novels and stories that introduced the brilliant and unflappable Sherlock Holmes and his partner, Dr. Watson, to the world. A Study in Scarlet is a drama of long-simmering revenge that ranges from the fog-bound streets of London to the pioneer settlements of Utah. The Sign of Four weaves together a stolen treasure from India, poison darts, and double-crossing thieves, while The Hound of the Baskervilles sets the legend of a diabolical hellhound and an old family curse against the backdrop of a moonlit moor. The short stories in this volume include such favorites as "A Scandal in Bohemia," "The Red-Headed League," "The Adventure of the Speckled Band," and "The Final Problem," tales that have thrilled generations of readers with Holmes's astounding powers of deduction.

Volume II contains the fourth of the Sherlock Holmes novels, The Valley of Fear, in which Holmes memorably faces his malignant archenemy, Professor Moriarty. The short stories collected here include such celebrated gems as The Adventure of Wisteria Lodge, The Adventure of the Red Circle, The Adventure of the Devil's Foot, The Adventure of the Sussex Vampire, and His Last Bow: The War Service of Sherlock Holmes. With the stories from the final collection, The Case-Book of Sherlock Holmes, published in 1927, this volume carries the venerable detective through to the very end of his enthralling four-decade career as one of the most beloved characters in literature.
