THE IMPOSSIBLE ROOM =================== A door in Node 19 opens into part of the Nitetime Garage. Not the present Garage. The banner is faded. The equipment is gone. Dust lies on the workbench, but the receiver still displays: 33 On the wall is a maintenance note dated after tonight. It says: FIELD OPERATORS MAY NOT RETURN BY SAME PATH The room may be future, memory, alternate state or network reconstruction. The receiver clicks once, and the door returns to Node 19 before you can test the distinction.
