The Blind Seal

Six prints. One counterfeit. Three links in the proof. A signed original has disappeared from the Last Light Print Studio. A counterfeit has taken its place. Compare the inspection records, rebuild a damaged dispatch ledger and work out who occupied each workstation. The Blind Seal is a self-contained English detective case for 1–2 players . It contains three linked deduction puzzles: an image-and-seal comparison, an ordering puzzle and a workstation logic puzzle. Solve them alone or together, then explain how the evidence identifies the culprit. What is included Equivalent 13-page PDFs in A4 and US Letter.
