The Adventure of the Three Gables

The story begins with a visit to 221B Baker Street from Steve Dixie, a black man and a cowardly ruffian who warns Sherlock Holmes to keep away from Harrow. Watson has no idea what this dimwitted fellow is talking about, but Holmes knows who he is and what the intrusion is all about, and manages to elicit some interesting information from him, knowing that Dixie is easily imposed upon.
