Information for Murder on the Orient Express at Yvonne Arnaud Theatre, Guildford (Play). The celebrated detective Hercule Poirot boards the legendary Orient Express, enjoying the prospect of a luxurious rail journey from Istanbul to Calais in the dead of winter. The train is surprisingly packed for the time of year; only the intervention of the manager secures Poirot a first class berth, alongside an intriguing and glittering company of international travellers. But just after midnight, the Orient Express screeches to a halt, marooned by a snowdrift. And by morning, one passenger is dead... Nobody can leave. A guard appears to be missing. A killer is in their midst. And Poirot must deploy his "little grey cells" on the most difficult case of his career: one that will force him to question his deepest beliefs.
