“That is so, Monsieur,” said the conductor. “That is why I thought the lady must have been dreaming.”
“But now it is easy,” continued M. Bouc. “Doubtless he meant to relock the communicating door, also, but perhaps he heard some movement from the bed and it startled him.”
“We have now,” said Poirot, “only to find the scarlet kimono.”
“True. And these last two compartments are occupied by men.”
“We will search all the same.”
“Oh! assuredly. Besides, I remember what you said.”
Hector MacQueen acquiesced willingly in the search. “I’d just as soon you did,” he said with a rueful smile. “I feel I’m definitely the most suspicious character on the train. You’ve only got to find a will in which the old man left me all his money, and that’ll just about fix things.”
M. Bouc bent a suspicious glance upon him.
“That’s only my fun,” added MacQueen hastily. “He’d never have left me a cent, really. I was just useful to him—languages and so on. You’re likely to be out of luck, you know, if you don’t speak anything but good American. I’m no linguist myself, but I know what I call Shopping and Hotel—snappy bits in French and German and Italian.”
His voice was a little louder than usual. It was as though he were slightly uneasy over the search in spite of his expressed willingness.
Poirot emerged. “Nothing,” he said. “Not even a compromising bequest!”
MacQueen sighed. “Well, that’s a load off my mind,” he said humorously.
They moved on to the last compartment. The examination of the luggage of the big Italian and of the valet yielded no result.
The three men stood at the end of the coach looking at each other.
“What next?” said M. Bouc.
“We will go back to the dining-car,” said Poirot. “We know now all that we can know. We have the evidence of the passengers, the evidence of their baggage, the evidence of our eyes. … We can expect no further help. It must be our part now to use our brains.”
He felt in his pocket for his cigarette case. It was empty.
“I will join you in a moment,” he said. “I shall need the cigarettes. This is a very difficult, a very curious, affair. Who wore that scarlet kimono? Where is it now? I wish I knew. There is something in this case—some factor—that escapes me! It is difficult because it has been made difficult. But we will discuss it. Pardon me a moment.”
He went hurriedly along the corridor to his own compartment. He had, he knew, a further supply of cigarettes in one of his valises.
He got it down and snapped back the lock.
Then he sat back on his heels and stared.
Neatly folded on the top of the case was a thin scarlet silk kimono embroidered with dragons.
“So,” he murmured. “It is like that. A defiance. Very well, I take it up.”
PART III
HERCULE POIROT SITS BACK AND THINKS

WHICH OF THEM?
M. Bouc. and Dr. Constantine were talking together when Poirot entered the dining-car. M. Bouc was looking depressed.
“Le voilà,” said the latter when he saw Poirot. Then he added, as his friend sat down, “If you solve this case, mon cher, I shall indeed believe in miracles!”
“It worries you, this case?”
“Naturally it worries me. I cannot make head or tail of it.”
“I agree,” said the doctor. He looked at Poirot with interest. “To be frank,” he said, “I cannot see what you are going to do next.”
“No!” said Poirot thoughtfully.
He took out his cigarette case and lit one of his tiny cigarettes. His eyes were dreamy.
“That, to me, is the interest of this case,” he said. “We are cut off from all the normal routes of procedure. Are these people whose evidence we have taken speaking the truth, or lying? We have no means of finding out—except such means as we can devise ourselves. It is an exercise, this, of the brain.”
“That is all very fine,” said M. Bouc. “But what have you to go upon?”
“I told you just now. We have the evidence of the passengers and the evidence of our own eyes.”
