thenâwell, I have faith in you! I am assured that it is no idle boast of yours. Lie back and thinkâuse (as I have heard you say so often) the little grey cells of the mindâand you will know! â
He leaned forward, looking affectionately at his friend.
âYour faith touches me, my friend,â said Poirot emotionally. âAs you say, this cannot be a difficult case. I myself, last nightâbut 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 nowâa problem lies ready to my hand.â
âYou accept then?â said M. Bouc eagerly.
â Câest entendu. You place the matter in my hands.â
âGoodâwe are all at your service.â
âTo 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.â
âMichel will get you those.â
The Wagon Lit conductor left the compartment.
âWhat other passengers are there on the train?â asked Poirot.
âIn 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.â
âThen it seems,â said Poirot slowly, âas though we must look for our murderer in the Istanbul-Calais coach.â He turned to the doctor. âThat is what you were hinting, I think?â
The Greek nodded.
âAt half an hour after midnight we ran into the snowdrift. No one can have left the train since then.â
M. Bouc said solemnly.
âThe murderer is with usâon the train nowâ¦.â

A W OMAN?
F irst of all,â said Poirot, âI should like a word or two with young M. MacQueen. He may be able to give us valuable information.â
âCertainly,â said M. Bouc.
He turned to the chef de train .
âGet M. MacQueen to come here.â
The chef de train left the carriage.
The conductor returned with a bundle of passports and tickets. M. Bouc took them from him.
âThank 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.â
âVery good, Monsieur.â
Michel in his turn left the carriage.
âAfter we have seen young MacQueen,â said Poirot, âperhaps M. le docteur will come with me to the dead manâs carriage.â
âCertainly.â
âAfter we have finished thereââ
But at this moment the chef de train returned with Hector MacQueen.
M. Bouc rose.
âWe are a little cramped here,â he said pleasantly. âTake my seat, M. MacQueen. M. Poirot will sit opposite youâso.â
He turned to the chef de train.
âClear all the people out of the restaurant car,â he said, âand let it be left free for M. Poirot. You will conduct your interviews there, mon cher? â
âIt would be the most convenient, yes,â agreed Poirot.
MacQueen had stood looking from one to the other, not quite following the rapid flow of French.
âQuâest ce quâil y a?â he began laboriously. âPourquoiâ?â
With a vigorous gesture Poirot motioned him to the seat in the corner. He took it and began once more.
âPourquoiâ?â then, checking himself and relapsing into his own tongue, âWhatâs up on the train? Has anything happened?â
He looked from one man to another.
Poirot nodded.
âExactly. Something has happened. Prepare yourself for a shock. Your employer, M. Ratchett, is dead! â
MacQueenâs mouth pursed itself in a whistle. Except
