Wagon-Lit

A courier is dead in Compartment Four of a 1960s sleeper express, the doctor has already called it a fall, and you have until the frontier at dawn. The whole world is one carriage: a corridor of numbered doors opening into compartments where passengers lie, evade and revise. Everything you learn becomes a card, and the game is really played on the corkboard — drag one statement onto another until a contradiction lights up and cracks open a question you could not previously ask. Name them with the file behind it, or they walk at the border.
