In “Death by Sudoku” by Kay Morgan sets her tale on the Oregon coast in a small village (Maiden’s Bay) where working the puzzles is basically an addiction for Liza Kelly, who creates the puzzles for the local publication, the Oregon Daily.
And as this is a cozy murder mystery, we’ve got to have a body! Liza (with a z) enters a sudoku tournament (yes, they exist, big time) and before she can fill in the first numbers, voila, her longtime friend and competitor is found dead! The friend had just told her that there were hidden clues with news story connections embedded in the puzzles. And before you can count to nine, the game is on! In so doing, of course, she involves the immediate world: her editor, her estranged husband, and an old high school boyfriend. (Yes, these complications retard the final solution, needless to say! But, hey, basically harmless!)
To be fair, of course, while the book is indeed a quick read (and with funny tidbits and helpful hints on how to work sudoku puzzles), it’s not much of a challenge on the “literary meter,” but for those of us not expert in these puzzles, it does provide a good background, all while Liza figure out the clues—and, of course, solves the puzzle, er, murders.
