The Valley of Fear (World Classics, Unabridged)

In this tale drawn from the note books of Dr Watson, the deadly hand of Professor Moriarty once more reaches out to commit a vile and ingenious crime. However, a mole in Moriarty's frightening criminal organization alerts Sherlock Holmes of the evil deed by means of a cipher. When Holmes and Watson arrive at a Sussex manor house they appear to be too late. The discovery of a body suggests that Moriarty's henchmen have been at their work. But there is much more to this tale of murder than at first meets the eye and Sherlock Holmes is determined to get to the bottom of it.

Sir Arthur Conan Doyle (1859-1930) was a Scottish author and physician best known for creating Sherlock Holmes, one of literature's most iconic detectives. Holmes, with his remarkable powers of observation and deduction, has become a symbol of logical reasoning. Doyle wrote four novels and 56 short stories featuring Holmes and his loyal friend, Dr. Watson. Beyond the Holmes series, Doyle was a versatile writer, producing works in historical fiction, science fiction, and supernatural tales. Despite his literary success, Doyle considered his historical novels, such as The White Company, to be his finest work. He was also deeply interested in spiritualism and wrote extensively on the subject in his later years.
