Matthew Stock (he/him) lives in St. Louis where he teaches high school algebra, constructs crosswords and annoys his cat, Scotch, who happens to be very bad at any kind of covert operations. He’s contributed puzzles to various outlets since late 2019, and he now runs his own website, happylittlepuzzles.com. He dares you to name a better spy movie than Spy Kids 3D: Game Over.
