To celebrate 35 years of professional puzzlemaking, I’ve put together PDF versions of two books I created in 2005 (for St. Martin’s Press and Random House). Punchline Puzzles contains 50 crosswords with an original cartoon in the center of each grid. AHA! is 125 pages of “clever crossword clue” puzzles. $10 each, both for $18.
