1,020 Suspect Entries. 16 Clues. One Mystery. One Final Answer.

Think you have what it takes to solve a detective's unfinished case. Put your deduction skills to the test with The File That Was Still Open, a printable detective logic puzzle for adults who love solving mysteries, eliminating suspects, and following evidence.

One book. One mystery. One answer. Can you find it?

The Mystery

An old police station is scheduled for demolition when a detective discovers a case file marked both closed and wanted.

A missing final page, conflicting records, and an unresolved search request raise questions about a case that should have been settled long ago.

As the six-part detective story unfolds, you'll work through the suspect register and eliminate impossible candidates using logic, observation, and deduction.

The truth is hidden in the evidence. Your job is to find it.

• Icon-based deduction: Interpret symbols associated with each suspect and the surrounding entries.
