The Cold Case Room · Case Files
The archive of the cases
nobody ever closed.
Murder mystery games built from police case files. Print them out or play on screen. No app, no hints — only the evidence.
Four collections, seven files each. Police reports, interrogations, the autopsy, the evidence and a sealed solution. Name the killer, then break the seal.

Nothing they did not.
No hints. No nudges. No app telling you when you are getting warm. Just the paperwork of a real investigation, and whatever you can make of it.
Doc 01
The police report
Who found the body, at what hour, and what the first officer wrote down before anyone had time to invent a story.
Doc 02
Six interrogations
Every suspect gets to speak. Every one of them lies about something. The trick is working out which lie is the one that matters.
Doc 03
Crime scene photos
Shot the way the police shot them. The detail that breaks the case is somewhere in these frames, in plain sight.
Doc 04
The autopsy
Time of death, cause of death, and the small medical contradiction that ruins somebody's alibi.
Doc 05
The evidence
Letters, receipts, phone records, a diary nobody was supposed to read. This is where motive hides.
Sealed
Do not open
The solution
Sealed for a reason. Open it only once you have named your killer, and see the whole case explained clue by clue.
Print it and spread it across the table, or keep it on the screen. Either way, the file is complete.
They opened the file.
Here is what happened next.
We argued for an hour
My husband was sure it was the brother. I was sure it was the wife. We spread the whole thing across the kitchen table and did not touch our phones once. Neither of us was right, which made it worse. And better.
Case ClosedI missed it by one line
Named my suspect, felt very pleased with myself, opened the solution. The clue was in the autopsy and I had read straight past it. Went back through the file just to see how badly I had been played. Beautifully, is the answer.
SolvedReplaced our Friday night
We used to sit there scrolling for something to watch and then watch nothing. Now Friday is a case. We are three files in and my only complaint is that we are running out.
SolvedPrinted it, and I am glad I did
Spread the photos out, pinned the suspects to a board, drew the string. My kids thought I had lost my mind. Then they sat down and helped.
Case ClosedActually hard, and that is the point
I read true crime constantly and expected to walk through this. I did not. The interrogations are written so well that every single suspect looks guilty for about ten minutes.
Case ClosedDownloaded it, played it that night
Bought it after dinner on a whim, had it open twenty minutes later. No box to wait for, nothing to assemble. Just a file, a pen, and a long argument with my sister.
SolvedEverything you are
about to ask.
No. Every file works two ways. Print it and spread the evidence across your table, which is how most detectives play it, or keep everything on a screen and solve it from the sofa. Both versions are complete, nothing is missing from either.
Anywhere from one to six. Solo works beautifully, since it is you against the file with nobody to talk you out of a bad theory. Two is the sweet spot for a night in. With a group, you split the documents and argue, which is where it gets loud.
Every case can be cracked with what is in the file. No hidden information, no twist that comes out of nowhere. The clues are all there, sitting in plain sight among a lot of things that are not clues at all. That is the whole difficulty.
Sixty to ninety minutes for most people, longer if you argue. The collection holds well over twelve hours of investigation in total. You can stop halfway, put the file down, and pick it back up a week later without losing the thread.
Once you know who did it, the mystery is gone. But a solved case is the best thing you can hand to somebody else. Most detectives pass their files on to friends and then watch them walk into exactly the same trap.
The collection comes with a Detective's Handbook that teaches you how to work a file: how to read a statement for the lie inside it, how to build a timeline, how to test a motive. Start with Case 001, which is the gentlest. By Case 006 you will not need the handbook at all.
No. Every case is written from scratch, built the way a real investigation is built. Nobody in these files ever existed, which means you can accuse whoever you like without anyone getting hurt.
Minutes after checkout, straight to your inbox. Nothing ships, nothing arrives, nothing gets lost in the post. Buy it after dinner and the file is open on your table before the evening is over.
