Some files are solved. Some letters refuse to stay lost.
Physical mystery case files, recovered documents, strange letters, photographs, reports, and evidence delivered to your door.
Dead Letter Bureau exists for the things that should have disappeared.
Misfiled evidence. Returned letters. Forgotten records. Police reports with missing pages. Photographs without names. Case files nobody wanted reopened.
Some of these documents become full investigations. Others arrive as fragments: strange mail, unresolved records, and pieces of stories that were never meant to reach you.
Every package is designed to feel like it came from a locked archive, a forgotten office, or a box that should have stayed sealed.
Open a full case file, receive a strange envelope, or enter the archive from wherever the trail begins.
