At the Tokatlian Hotel, Poirot surreptitiously observes Mr. Ratchett and Mr. MacQueen eating in the restaurant. He does not like Mr. Ratchett because he gives off a savage impression. Poirot also runs into his old friend M. Bouc and begins talking jovially with hum.
On the Orient Express, there is only one second class sleeping berth left on the whole train whih Poirot shares with Hector MacQueen. MaQueen deferentially asks Poirot if he has made a mistake but the conductor told him that this was the only bed left.
Mr. Ratchett peremptorily asks Poirot if he will help him. He believes that he has enemies that are going to try and hurt him while on the train.
