About these worksheets

Each mystery opens with a case scenario — the setting, the incident, and the list of suspects who had opportunity. Numbered clues follow; read them in order and cross-reference as you go. Circle or eliminate suspects in the choices row at the bottom, then check the answer key on the last page.

The answer key names the correct suspect, gives the answer letter (A/B/C/D…), and includes the two decisive proof steps — enough to verify your reasoning without giving away the whole deduction chain upfront.

If you'd rather solve interactively, play online with hints, timing, and progress tracking.
