A real case from the series. Four passengers, one body, one truth.
HOW A CASE WORKS
Read the statements
Each suspect left a clue: where they sat, what they stood beside, which room they swear they were in.
Work the grid
One person per row and column — sudoku rules meet floor-plan logic. Cross off squares until each suspect has only one place left to stand.
Name the killer
The victim was found alone with one other person. Place everyone, look at the victim’s room, and make the arrest.
THE CASE FILES
Full-color themed editions and travel-friendly volumes. Every case verified to a single logical solution.
