It's 1894, and Sherlock Holmes has been presumed dead for the previous two and a half years. Watson's story, "The Final Problem," seems to confirm the loss of the great detective.

The evidence points squarely at Dr. Watson, who had an altercation with the victim shortly before his death. Can you uncover new evidence and expose the murderer?
