The Sealed Chamber BETA

The room was locked. The reasoning wasn't.

A fair-play mystery: every clue you need is on the page, and exactly one solution survives them. Name the culprit and the method — then give the chain by which you know it. A lucky guess scores 30. The chain is the game.

How you're scored — the rubric (read before you play)
Solution30Correct culprit and method
Chain Validity30Each inference must follow from clues in the text
Clue Coverage25Every load-bearing clue used — an unused clue is an unclosed door
Economy15The shortest valid chain; no speculative padding
Elegance+10Name the misdirection and why the author placed it

Verdicts: CASE CLOSED (85+) · COMMITTED FOR TRIAL (60–84) · OPEN VERDICT (under 60). A correct accusation without a valid chain caps at 30 — the guess is not the game.
