Shrike answers
No.
Nobody knows if that was true
The house does. It wrote the answer down the moment it was given, and sealed it.
The file
Sixteen people walk in here. Five sit down tonight and one of the five is you. Every question you ask is a question about which of these you are.
Some pairs are separated by exactly one thing. Kestrel and Magpie differ by a hat. One lie about a hat turns you into somebody else entirely.

Chapter
It proves nothing. A slow answer can be an honest one, and a practised liar answers on the beat.
But every hesitation at that table is on the record, and everyone knows it — which makes the pause itself something you have to perform. That is the whole scene, really. Not the questions. The four seconds afterwards, while four people decide what your four seconds meant.
Chapter
The barman puts five glasses in front of you the first time you sit down. Asking is free. Answering is free. Lying is free.
A glass buys one thing: the right to stop the room.
You pay it to the person you are accusing, before anything is checked — you buy them a drink, then call them a liar to their face. Then the house opens the verdict. Caught them, and they are out and the glass stays yours. Wrong, and you are out, and they have already been paid for the insult.
How the house does it
Everything above is one row in a ledger. What is readable, and by whom, is the entire game.
Case file 00137 — seat 3
Inco Lightning
identity encrypted · granted to seats 1, 2, 4, 5
denied to seat 3 · the seat that owns it
That last line is the whole trick. An access grant pointed away from its owner cannot be written on a chain where state is public — and without it there is no game to play.
The regulars
Five regulars keep the round going, each lying in a different way. Walk in alone at three in the morning and there is still a game.
Answers honestly every time and accuses only on a contradiction it can prove. The one you calibrate the others against.
Deceives about a quarter of the time, at random, with no plan behind it. Impossible to read because there is nothing to read.
Tells the truth all night, then lies precisely on the answer that would have finished you.
Honest until you cross it. Catch Mirror in a lie and it will not forget, and from then on it deceives you and only you.
Never lies, but does not wait for proof. Honest players lose bonds here, and that is the only thing stopping the table from auditing everything.
Drag sideways
Last thing
Three names are left on your list. The room has gone quiet. Make your accusation.
Somebody lied about a hat, four questions ago, and you never bought the glass to find out.
Five glasses on the house. Nothing here is worth real money, and the round is running whether or not anyone else shows up.
