The case files

Choose a cold case file to solve

Every case is a self-contained cold case: an original investigation that stalled, handed to you exactly as the detectives left it. Nothing has been removed. Nothing has been simplified. Every case comes two ways: play online (the first case is free), or download the printable PDF with the solution sealed separately.

How to play

How the murder mystery game works: read, cross-reference, accuse

This is not a puzzle game with a story attached. It is an investigation. The file is the game.

1
Open the file

Online or on paper. Every document is sorted into the folders a real detective would use: Police Reports, Forensics, Witness Statements, Photographs, Records, Personal Documents, Press. Open them all.

2
Cross-reference everything

No single document names the killer. Statements, records and reports have to be read against each other, and nothing in the file tells you which ones to compare. Keep notes — on paper, like they did.

3
Close the case

When you are certain, name the killer. You get one accusation: right or wrong, the case closes and the solution file shows what the documents prove. There are no hints.

Why this site

Like boxed murder mystery case files, without the box

If you have ever worked through a boxed murder mystery case file at the kitchen table, you know the format: a stack of realistic documents, a set of suspects, and the slow satisfaction of a timeline that finally closes. This site is that format, built for the screen — with documents that read like the real thing, a strict "two sources for every conclusion" rule, and nobody telling you where to look.

What we left out on purpose: hint buttons, guided objectives, a notes tab, a timeline builder, a "people" tab that summarizes the suspects for you. Real files do not have those. You are the detective. The folder is the whole game.

"Nothing has been removed. Nothing has been added except this memo and a 2023 newspaper feature that summarizes what the town remembers."— Cold Case Unit memo, File 93-1114
"Everybody in this town has a theory."— Jenna Stoddard-Galindo, 2023
FAQ

Murder mystery game FAQ

Is the first case really free?

Yes. Last Call at the Bluebird is complete and free, with no account required. Every other case comes with Premium: $19.99 a week, $39.99 a month or $69.99 a year, for online play with up to 8 friends. Case PDFs are sold separately. See pricing.

Can I play on my phone?

Yes. The file is built for phone screens: folders open in a list, each document opens full-screen with zoom and next/previous, and your progress is saved on the device. Prefer paper? Every case, including the free one, is also a printable PDF.

Can we play as a group?

Yes. Tap Play with friends inside a case to open a room. Everyone joins from their own phone with a six-letter code, sees what the others have read, talks it through in the room chat, and votes in secret. When the host has Premium, you can also switch on voice chat and talk while you read. The host reveals the votes and the solution opens for everyone at once. One screen and a notepad works too.

Are there hints?

No. Not in the file, not on the site. If you are stuck, read the documents you skimmed. The answer is always supported by at least two of them.

How long does a case take?

Two to three hours for a careful reader. Longer with a group. There is no timer.
