I met Francis Heaney a couple of times at my kind of parties—where I’m the dumbest person in the room. He’s one of those puzzle league types and he’s just posted on his blog that he’s got a new book coming out: The Sudoku Code, with Frank Longo. The cover has the tagline “200 Sudoku Puzzles. One Answer. Can You Find It?” It also has a version of Da Vinci’s illustration of Carthweel Man, which makes this most intentionally wackadoo spin-off of the Da Vinci Code blech-ha-ha I’ve seen yet.
