Volume 1 of the Sherlock Holmes series is absolutely great for introducing the great detective Sherlock Homes and his companion, Dr. Watson, who has accompanied Holmes in many of his adventures. Volume 2 includes all different types of mysteries, like murder, crime, blackmail, and other bloodthirsty mysteries. It's thrilling to read, and I recommend it to anyone who loves mysteries. These books will definitely make you want to buy them all. Well worth the time.
