Professor Moriarty: Professor James Moriarty is a fictional character and the main antagonist in some of the Sherlock Holmes stories written by Sir Arthur Conan Doyle.

The character was introduced primarily as a narrative device to enable Doyle to kill Sherlock Holmes, and only featured in two of the Sherlock Holmes stories.  However, in many adaptations, he has been given a greater prominence and treated as Holmes' archenemy.
