Not just another number grid
Every puzzle has
a suspect.
Death by Deduction combines traditional 9 × 9 Sudoku with short fictional murder cases. Each investigation pairs a puzzle and suspect line-up with its own Detective’s Notes page.
The mystery is part of the solution: three marked squares produce a file number that points to one suspect. You do not need to calculate sums, download an app or guess who did it.

Read the preview’s briefing and page description
Case 01, Beginner. The Body in the Bramble Walk. Thornleigh Hall, Gloucestershire.
Sir Edmund Thornleigh was found beneath the yew arch at dawn, his pocket watch stopped at 11:14. The gate to the bramble walk had been locked from the inside.
The notes page contains an evidence board, six suspects with file numbers, space for observations and a final accusation. The puzzle page contains a 9 × 9 Sudoku grid and the matching line-up. Evidence A is at row 4, column 7; B at row 6, column 5; C at row 8, column 1. The web previews show the printed layout; they are not an interactive or fully transcribed playable puzzle.
