Lazarus places two folded cards on the counter. “Excellent. Our filing system has developed a plot. Take a desk.”
“The filing is imperfect. The facts are sound. Do distinguish the two.” — The_Simurgh
First, arrange the chairs
Bring a fellow clerk, or take both desks.
With another reader
Share this page’s address in a conversation you already have. Agree who takes Card A and who takes Card B. Open only your own card, then exchange clues there and work out the ledger together.
On your own
Open both cards and compare the clues at your own pace. You have the same case and the same answer. The Bureau is happy to lend you the second chair.
This page does not pair visitors or send messages. Each card alone leaves several possible answers. Both cards together give one complete ledger.
Prefer plain text? Read the case and choose a clue card.
For separate copies, open Card A only or Card B only and use your browser’s Print command. Each card includes the shared facts. Agree who keeps the shared answer sheet: it has a blank ledger and optional notes you can print or save locally. It does not sync between desks.
Printing this illustrated page leaves out both clue cards, the hint and the solution, even if you have opened them. Print the separate cards and answer sheet for a paper game.

Read this part at both desks
What the Bureau knows
Each visitor went to one different room and returned one different object there. Use every name, object and room exactly once. Every clue is true; the story adds no hidden rules.
The three lists below are independent. Their positions do not indicate matches.
Three visitors
- Iona
- Moss
- Pip
Three objects
- A pocket moon
- A folded tomorrow
- A bottled echo
Three rooms
- The Winter Room
- The Clock Room
- The Map Room
Your task: name the object each visitor returned and the room they returned it to. A scrap of paper may be promoted to acting ledger.
The clerks’ surviving notes
Choose your card.
For two readers, leave your partner’s card folded. For one reader, open both. Close any card by selecting its heading again.
Open Card A — the arrivals deskThree clues · keep the other desk’s card folded if playing together
Card A · arrivals desk
- Iona did not return the pocket moon.
- The folded tomorrow was returned to the Winter Room.
- Moss did not visit the Winter Room.
Your card is complete. The other desk has the rest of the evidence.
Open Card B — the returns deskTwo clues · keep the other desk’s card folded if playing together
Card B · returns desk
- The pocket moon was returned to the Map Room.
- Iona did not visit the Winter Room.
Your card is complete. The other desk has the rest of the evidence.
The folds keep clues out of sight until you choose to open them. They are not private or secret compartments.
No inspector is waiting
A little assistance, if wanted.
Open a small hint
Compare what the two cards say about the same room. Knowing who could not have gone there may tell you who did.
Still stuck? Open four gradual hints, one at a time. The first repeats this nudge; later folds help with the next deductions.
Ready to check your completed ledger?
One more fold protects the answer. Open it when you want to see all three records and the deductions behind them.
Reveal the full solution and explanation
| Visitor | Object returned | Room |
|---|---|---|
| Iona | Bottled echo | Clock Room |
| Moss | Pocket moon | Map Room |
| Pip | Folded tomorrow | Winter Room |
How the notes fit together
- Card A rules Moss out of the Winter Room; Card B rules Iona out. So Pip went to the Winter Room.
- Card A places the folded tomorrow in that room. So Pip returned the folded tomorrow.
- The bottled echo and pocket moon remain for Iona and Moss. Card A says Iona did not return the moon. So Iona returned the bottled echo, and Moss returned the pocket moon.
- Card B places the pocket moon in the Map Room. So Moss went to the Map Room. Only the Clock Room remains for Iona.
Returned to the correct impossibility
Lazarus enters the last room in the ledger. “A triumph of correspondence. I shall order a commemorative paperclip.”
The clerks’ conversation
