“You accept then?” said M. Bouc eagerly.
“C’est entendu. You place the matter in my hands.”
“Good—we are all at your service.”
“To begin with, I should like a plan of the Istanbul-Calais coach, with a note of the people who occupied the several compartments, and I should also like to see their passports and their tickets.”
“Michel will get you those.”
The Wagon Lit conductor left the compartment.
“What other passengers are there on the train?” asked Poirot.
“In this coach Dr. Constantine and I are the only travellers. In the coach from Bucharest is an old gentleman with a lame leg. He is well known to the conductor. Beyond that are the ordinary carriages, but these do not concern us, since they were locked after dinner had been served last night. Forward of the Istanbul-Calais coach there is only the dining-car.”
“Then it seems,” said Poirot slowly, “as though we must look for our murderer in the Istanbul-Calais coach.” He turned to the doctor. “That is what you were hinting, I think?”
The Greek nodded. “At half an hour after midnight we ran into the snowdrift. No one can have left the train since then.”
M. Bouc said solemnly, “The murderer is with us—on the train now. …”

A WOMAN
“First of all,” said Poirot, “I should like a word or two with young Mr. MacQueen. He may be able to give us valuable information.”
“Certainly,” said M. Bouc. He turned to the chef de train. “Get Mr. MacQueen to come here.”
The chef de train left the carriage.
The conductor returned with a bundle of passports and tickets. M. Bouc took them from him.
“Thank you, Michel. It would be best now, I think, if you were to go back to your post. We will take your evidence formally later.”
“Very good, Monsieur,” said Michel, and in his turn left the carriage.
“After we have seen young MacQueen,” said Poirot, “perhaps M. le docteur will come with me to the dead man’s carriage.”
“Certainly.”
“After we have finished there—”
But at this moment the chef de train returned with Hector MacQueen.
M. Bouc rose. “We are a little cramped here,” he said pleasantly. “Take my seat, Mr. MacQueen. M. Poirot will sit opposite you—so.”
He turned to the chef de train. “Clear all the people out of the restaurant car,” he said, “and let it be left free for M. Poirot. You will conduct your interviews there, mon cher?”
“It would be the most convenient, yes,” agreed Poirot.
MacQueen had stood looking from one to the other, not quite following the rapid flow of French.
“Qu’est-ce qu’il y a?” he began laboriously. “Pourquoi—?”
With a vigorous gesture Poirot motioned him to the seat in the corner. He took it and began once more.
“Pourquoi—?” Then checking himself and relapsing into his own tongue: “What’s up on the train? Has anything happened?”
He looked from one man to another.
Poirot nodded. “Exactly. Something has happened. Prepare yourself for a shock. Your employer, M. Ratchett, is dead!”
MacQueen’s mouth pursed itself into a whistle. Except that his eyes grew a shade brighter, he showed no signs of shock or distress.
“So they got him after all,” he said.
“What exactly do you mean by that phrase, Mr. MacQueen?”
MacQueen hesitated.
“You are assuming,” said Poirot, “that M. Ratchett was murdered?”
“Wasn’t he?” This time MacQueen did show surprise. “Why, yes,” he said slowly. “That’s just what I did think. Do you mean he just died in his sleep? Why, the old man was as tough as—as tough—”
He stopped, at a loss for a simile.
“No, no,” said Poirot. “Your assumption was quite right. M. Ratchett was murdered. Stabbed. But I should like to know why you were so sure it was murder, and not just—death.”
MacQueen hesitated. “I must get this clear,” he said. “Who exactly are you? And where do you come in?”
“I represent the Compagnie Internationale des Wagons Lits.” Poirot paused, then added, “I am a detective. My name is Hercule Poirot.”
If he expected an effect he did not get one. MacQueen said merely, “Oh! yes?” and waited for him to go on.
“You know the name perhaps?”
