MonsieurâI rememberâI told you. It was the American lady. She had rung several times.â
âI recollect,â said Poirot. âAnd after that?â
âAfter that, Monsieur? I answered your bell and brought you some mineral water. Then, about half an hour later, I made up thebed in one of the other compartmentsâthat of the young American gentleman, M. Ratchettâs secretary.â
âWas M. MacQueen alone in his compartment when you went to make up his bed?â
âThe English Colonel from No. 15 was with him. They had been sitting talking.â
âWhat did the Colonel do when he left M. MacQueen?â
âHe went back to his own compartment.â
âNo. 15âthat is quite close to your seat, is it not?â
âYes, Monsieur, it is the second compartment from that end of the corridor.â
âHis bed was already made up?â
âYes, Monsieur. I had made it up while he was at dinner.â
âWhat time was all this?â
âI could not say exactly, Monsieur. Not later than two oâclock, certainly.â
âAnd after that?â
âAfter that, Monsieur, I sat in my seat till morning.â
âYou did not go again into the Athens coach?â
âNo, Monsieur.â
âPerhaps you slept?â
âI do not think so, Monsieur. The train being at a standstill prevented me from dozing off as I usually do.â
âDid you see any of the passengers moving up or down the corridor?â
The man reflected.
âOne of the ladies went to the toilet at the far end, I think.â
âWhich lady?â
âI do not know, Monsieur. It was far down the corridor, and she had her back to me. She had on a kimono of scarlet with dragons on it.â
Poirot nodded.
âAnd after that?â
âNothing, Monsieur, until the morning.â
âYou are sure?â
âAh, pardon, you yourself, Monsieur, opened your door and looked out for a second.â
âGood, my friend,â said Poirot. âI wondered whether you would remember that. By the way, I was awakened by what sounded like something heavy falling against my door. Have you any idea what that could have been?â
The man stared at him.
âThere was nothing, Monsieur. Nothing, I am positive of it.â
âThen I must have had the cauchemar, â said Poirot philosophically.
âUnless,â said M. Bouc, âit was something in the compartment next door that you heard.â
Poirot took no notice of the suggestion. Perhaps he did not wish to before the Wagon Lit conductor.
âLet us pass to another point,â he said. âSupposing that last night an assassin joined the train. It is quite certain that he could not have left it after committing the crime?â
Pierre Michael shook his head.
âNor that he can be concealed on it somewhere?â
âIt has been well searched,â said M. Bouc. âAbandon that idea, my friend.â
âBesides,â said Michel, âno one could get on to the sleeping car without my seeing them.â
âWhen was the last stop?â
âVincovci.â
âWhat time was that?â
âWe should have left there at 11:58. But owing to the weather we were twenty minutes late.â
âSomeone might have come along from the ordinary part of the train?â
âNo, Monsieur. After the service of dinner the door between the ordinary carriages and the sleeping cars is locked.â
âDid you yourself descend from the train at Vincovci?â
âYes, Monsieur. I got down on to the platform as usual and stood by the step up into the train. The other conductors did the same.â
âWhat about the forward door? The one near the restaurant car?â
âIt is always fastened on the inside.â
âIt is not so fastened now.â
The man looked surprised, then his face cleared.
âDoubtless one of the passengers has opened it to
