Numbers Never Lie, But People Do

When renowned Sudoku champion Victor Thornton is found dead during Enigma Grove's first puzzle tournament, puzzle shop owner Tillie Maze notices something odd about the half-completed grid beside his body. The peculiar blue markings don't follow Sudoku rules—they're mapping something far more valuable than a number puzzle.

As Tillie and the mathematical prodigy Cipher Twins analyze the mysterious pattern, they discover Victor was secretly buying strategic properties throughout town, blocking a developer's plans for a massive resort. With the help of her puzzle-loving friends, Tillie must decode the deadly pattern connecting Victor's final Sudoku puzzle to his murderer before Enigma Grove's unique character is forever transformed.

In this third installment of the beloved Piece by Piece Mysteries, Tillie proves once again that solving puzzles and solving crimes require the same skills: recognizing patterns, connecting seemingly unrelated pieces, and filling in the blanks to reveal the complete picture—even when the solution might prove deadly.
