The Valley of Fear matches Holmes against his archenemy, the master of imaginative crime, Professor Moriarty. In addition, the loyal Dr. Watson has faithfully recorded Holmes’s feats of extraordinary detection in such famous cases as the thrilling The Adventure of the Red Circle and the twelve baffling adventures from The Case Book of Sherlock Holmes. Conan Doyle’s incomparable tales bring to life a Victorian England of horse-drawn cabs, fogs, and the famous lodgings at 221B Baker Street, where for more than forty years Sherlock Holmes earned his undisputed reputation as the greatest fictional detective of all time.
