♥ Nothing Better Than Reading!! ♥ discussion

Since my upcoming book is all about riddles, which is your favourite book that features riddles and puzzles and codes?

And no Dan Brown...that's the most obvious answer. Any other writers who have dabbled in riddles and puzzles?

Nah.....can't think of any...except of course Dan Brown:) And Ahswin Sanghi too, though I didn't like his Krishna Key.
