Book excerpt: To solve or not to solve: that’s not the question about this super-sized follow-up to the extremely popular World’s Longest Crossword Puzzle—which has already sold 50,000 copies and was one of Gene Shalit’s gift book picks on the Today show. Crossword lovers will instantly want to get out their pencils and give it a try. But can they actually manage to complete every one of the 8,424 squares? One little hint that might help: Hamlet’s famous soliloquy—every word of it—runs the entire length of the puzzle. The crossword gets harder and harder as you move from left to right, and no two answers are the same.
