Matt Gaffney is one of two dozen people who earns a living as a cruciverbalist. In Gridlock he provides an insider’s look at the people who put that puzzle in your paper every day. With verve and gusto, Gaffney traces his own starving-artist struggle to find paying puzzle gigs, including marketing hip crosswords to the Gen-X market. He then moves on to topics like the effect of computers on crossword writing, including a man versus machine battle he stages to see who writes better crosswords; the ever-evolving crossword puzzle book market, where a top-selling series now has books shaped like a toilet seat; and a trip to the American Crossword Puzzle Tournament, where the “Cru” (collective slang noun meaning “the crossword puzzle writing community”) hangs out in person once a year. Gridlock also features an interview with crossword rock star Will Shortz.
