Red string found spanning the boarding-house wall
The Clue Board · every hand its own thread
The house supplies the corkboard and holds its tongue. Everything the investigators have met — persons, rooms, letters, handouts — can be pinned to a shared board and strung with red thread, dragged and rearranged by every member of the circle, live.
Each investigator ties their own colour of string, so the board remembers who drew which connection. The Keeper sees the party's working theory take shape — and says nothing.
Between sittings the board stays exactly as it was left. Half the fun of a mystery is being wrong on record; the board keeps the record.

The voice was not his own Scenery that moves of its own accord Letters arrive for guests who never gave their names He alone heard the whispering One hundred faces on the wheel "I merely wrote what the room told me" Spiritualists convene across impossible distances Not one sitting missed Blows exchanged properly Investigators made while you wait Lessons retained Papers kept in order Persons supplied The circle's wall Weather supplied Discretion assured Interruptions staged
