Do that.
Interview the passengers on the train, view the body, examine what clues there are, and then – well, I have faith in you!
I am assured that it is no idle boast of yours.
Lie back and think – use (as I have heard you say so often) the little grey cells of the mind – and you will know!” He leaned forward, looking affectionately at the detective.
“Your faith touches me, my friend,” said Poirot emotionally. “As you say, this cannot be a difficult case.
I myself last night – but we will not speak of that now.
In truth, this problem intrigues me.
I was reflecting, not half an hour ago, that many hours of boredom lay ahead whilst we are stuck here.
And now – a problem lies ready to my hand.”
“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.
