Case File: The Empty Apartment

Apartment 4B is locked from the inside.

The tenant is gone. Their phone is still on the kitchen counter. Nothing valuable appears to be missing. And every photograph has been carefully removed from every frame.

Case File: The Empty Apartment is a solo detective journaling RPG for one player, a standard deck of cards, and a journal.

There is no prewritten culprit and no fixed solution. You generate the clues, connect the evidence, manage contradictions and pressure, then build a final reconstruction that must actually fit the case you created.
