OK, singular lack of interest all round, it seems :) Anyway, here is my quick 10. I thought these were the most complex, most consistent and most entertaining characters that I had read so far.
1. Albus Dumbledore
2. Lord Elmsworth
3. Sherlock Holmes
4. Long John Silver
5. Severus Snape
6. Bertie Wooster
7. Arthur Dent (bumbling Englishman tripping through time and space, completelty out of his depth: from the Hitchhikers Guide to the Galaxy by Douglas Adams)
8. Dirk Gently (a detective who believes in the fundamental interconnection of everything in the universe and thus tries to solve cases in a 'wholistic' manner. Created by Douglas Adams)
9. Captain Hastings (another bumbling Englishman!)
1o. Scarlett O'hara
Now, anyone else wants to go?
