ETON

Not available

This clue refers to Eton College, the famous British boarding school. The "111-Across" is likely a fictional character (such as James Bond, who attended Eton in some versions), while his "creator" is the author who also went there—like Ian Fleming, Bond’s creator, who was an Eton alum. The answer plays on the real-life connection between the character and the writer’s shared education.
