The Misplaced Postcard — A Free Printable Mini Mystery

One lost postcard. A small mystery you can finish.

The night clerk has mixed up a delivery. Rebuild its three-stop route, read the sorting ledger and match the recovered word with the postcard picture. All the evidence is in front of you.

A complete free print-and-play mini case with hints, a deduction and an ending. No locks, cutting, hidden clues or paid software.

1. Choose A4 or US Letter. The content is the same.
2. Print pages 1–2 for players. Keep page 3 face down: it contains hints, the answer and the ending.
3. Bring a pencil. Work alone or compare reasoning with someone else.

The case uses English reading, ordering and a letter lookup. No timer, age guarantee or measured duration is claimed. A host can read aloud or offer the included hints.
