Mystery Adventures in a League of Their Own

Why This Mystery Had to Go Digital

Authenticity Demanded It.

We considered doing it the old way—letters, paper clues, maybe a wax seal or two. But the truth is: a letter is not a telegram, and a typed transcript is no substitute for a radio communique arriving at just the right moment.

To create a mystery that feels like 1938, we had to go beyond vintage props.
We had to recreate how information actually moved in that era—through telegrams, broadcasts, and real-time intelligence dispatches.

That kind of historical realism?
It just wasn’t possible in a physical box.

Desktop RPG Was the Only Way Forward:

Telegrams arrive mid-investigation. Not all at once in a packet. No peaking.
Radio transmissions can interrupt your theory. Or confirm it—if you’re sharp.
Field agents don’t wait for mail. They need instructions now.

The technology to mimic that 1930s rhythm of urgency and delay—it didn’t exist at scale until just recently. But now, using modern automation, conditional triggers, and timed communications, we’ve made it possible.

This isn’t a compromise.

It’s the only way to do it right.

Welcome to the League.

Your briefing awaits.

About the Mysteries...

The Architects Behind the Case

The Storycrafter

The human architect of the narrative. Every suspect, every discrepancy, every turning point is built by a mind trained in both structure and misdirection. AI assists with research and imagery, but the mystery itself is forged by hand — deliberately, precisely.

The Elementalist

The craftsperson responsible for the world’s components: aged dossiers, telegrams, fragments, communiqués, and the atmospheric materials that give the case its tactile credibility. Every element you encounter is constructed as if it were pulled directly from a field archive.

The Tracksmith

The hidden engineer of consequence. The Tracksmith crafts the branching paths, the timed deliveries, the divergent outcomes. Their work ensures that your decisions do not merely move the story — they change it.

Together, these three roles created the investigation now in your hands: The Case of the Missing Mechanism.

Good luck,

Dr. Theosiphus Coggs
Master Mysteriologist

Common Queries (or CQs, as we call them)

Do I get Something Immediately When I Sign Up?

You can jump right in as soon as you sign up, but you’ll receive an official confirmation of your assignment. Watch for that email, as you will want to mark the sender as safe.

You are securing your place in League history.

Is this a box of riddles? A puzzle? A video game? A Story?

None of the above — and a little of all.

This is a living investigation. The League employs a first-rate team of Field Agents that you guide using real-time transmissions and evidence. The Field Agent’s response time is based on real world factors he or she would have faced in the time period in which your case takes place. Your response time is based on your ability to get back to your desk and read through the clues that your Field Agent sends you.

Your choices affect the outcome.

What do I need to participate?

Just a browser and a mind built for deduction. No downloads, no printing, no setup.

You might choose to print out your telegrams sent by your assigned Field Agent, but that choice is up to you. The same goes for the documents on your desktop. You can always go back and retrieve your telegrams again, using the special code provided by the League HQ.

This experience, though, is designed to be a paperless endeavor, experienced best on a desktop, laptop, or a tablet in Landscape mode.

Can I work alone or with others?

Either. The League does not monitor collaboration. However, only one Mysteriologist will be credited per account.

Working as a team could help expedite the mission when clues arrive via telegram or radio broadcast, but that will be entirely up to you.

Just like everything else in the League of Mysteriologists, your choice creates your experience.

What happens if I choose the wrong path?

The case will continue. Some outcomes are irreversible. The League archives all missteps for analysis.

You can backtrack, reroute, follow up on old clues… the choice is yours. But, you do have one mission, and distractions could keep you from solving it in time.

How long do I have to crack the case?

Each assignment lasts as long as the website is up. A typical case could take as little as 3 to 5 days (if you’re REALLY good!) or up to two weeks or more if you get drawn off track or decide to follow up on other leads.

Although the system responds in real time for the era, we understand that you have a life outside your new role as an Associate Consulting Mysteriologist. Your Field Agent won’t keep you waiting, but the case isn’t delayed by your response time; it picks up exactly where you left off.

All the fun, all the challenge, and the only downside comes from the potential consequences of your choices, not your schedule.

The Consulting Mysteriologist Program is a free membership experience for those who prefer their games rich with story, consequence, and discovery. You can leave a gratuity at the end of the game, like a reverse crowdfunding, where you get to play the game before you decide if you’re going to pay for it.

This is not a puzzle to solve in isolation. It’s a living narrative—and you are at the heart of it. Gratutities are not expected, but will be greatly appreciated, and will give us the opportunity to make bigger, better experiences even faster.

Get your first telegram from the League of Mysteriologists

Give it a try! Get your first telegram right here, right now. Just use the secret key code fc525 when prompted below, and receive a Mini-Mystery back from League Headquarters. If you’re lucky, someone may be at the telegraph office waiting for your message.

By skipping the shipping, we gave ourselves the freedom to:

Create branching case files where your choices change the outcome
Script radio briefings that drop intel at just the right moment
Deliver League telegrams that react to your actions in real time
Build a world-class archive of unfolding mysteries you’ll help shape

You’re not buying a box.
You’re entering a world.

No Boxes. No Props. No Gimmicks. Just the Mission.

Most mystery experiences charge you $30 or more to ship a cardboard box full of trinkets, photocopies, and plastic artifacts.

We don’t.

Instead of printing and packing paper clues, we used every cent of that budget to build something deeper—a living, breathing mystery that evolves over time.

You’re not just reading. You’re responding.
You’re not just solving puzzles. You’re guiding investigations.
You’re not just playing. You’re in the story—with real decisions, real consequences, and a role only you can play.
