This volume is comprised of six novels, all of which are set in criminal-ridden nineteenth-century London. The novels were written by Scottish writer Sir Arthur Conan Doyle (1859-1930). The first three novels -- The Adventures of Sherlock Holmes, The Memoirs of Sherlock Holmes and The Return of Sherlock Holmes -- consist of twelve short stories each. A Study in Scarlet recounts the stunning tale of murder and betrayal, which ends in a way that is unexpected from that in which it starts. The Sign of Four is the case of a classic jewelry theft, and, finally, The Hound of the Baskervilles is a mysterious story in which it is narrated how a wealthy family is haunted by the curse of a blood-thirsty hound.
