The Mystery of the Blue Train

"Not at roulette."

Knighton shot a swift glance at him. His own face became troubled. He spoke hautily, with a touch of deference. "I wonder, are you busy, M. Poirot? There is something I would like to ask you about."

attitude that I went down privately and had an interview with the lady."

"Eh bien?"

"The difficulty was that she insisted on seeing Mr. Van Aldin himself. I softened his message as much as I possibly could. In fact-to be candid-I gave it in a very different form. I said that Mr. Van Aldin was too busy to see her at present, but that she might make any communication she wished to me. That, however, she could not bring herself to do, and she left without saying anything further. But I have a strong impression, M. Poirot that that woman knows something."

"This is serious," said Poirot quietly.

"You know where she is staying?"

"Yes." Knighton mentioned the name of the hotel.

"Good," said Poirot; "we will go there immediately."

The secretary looked doubtful.

"And Mr. Van Aldin?" he queried doubtfully.

"M. Van Aldin is an obstinate man," said Poirot drily. "I do not argue with obstinate men. I act in spite of them. We will go and see the lady immediately. I will tell her that you are empowered by M. Van Aldin to act for him, and you will guard yourself well from contradicting me."

Knighton still looked slightly doubtful, but Poirot took no notice of his hesitation.

At the hotel, they were told that Mademoiselle was in, and Poirot sent up both his and Knighton's cards, with "From Mr. Van Aldin" pencilled upon them.

Word came down that Mademoiselle Mirelle would receive them.

When they were ushered into the dancer's apartments, Poirot immediately took the lead.

"Mademoiselle," he murmured, bowing very low, "we are here on behalf of M. Van Aldin."

"Ah! And why did he not come himself?"

"He is indisposed," said Poirot mendaciously;

"the Riviera throat, it has him in its grip, but me, I am empowered to act for him, as is Major Knighton, his secretary.

Unless, of course. Mademoiselle would prefer to wait a fortnight or so."

If there was one thing of which Poirot was tolerably certain, it was that to a temperament such as Mirelle's the mere word "wait" was anathema.

"Eh bien, I will speak. Messieurs," she cried. "I have been patient. I have held my hand. And for what? That I should be insulted!

Yes, insulted! Ah! Does he think to treat Mirelle like that? To throw her off like an old glove. I tell you never has a man tired of me. Always it is I who tire of them."

She paced up and down the room, her slender body trembling with rage. A small table impeded her free passage and she flung it from her into a corner, where it splintered against the wall.

"That is what I will do to him," she cried, "and that!"

Picking up a glass bowl filled with lilies she flung it into the grate, where it smashed into a hundred pieces.

Knighton was looking at her with cold British disapproval. He felt embarrassed and ill at ease. Poirot, on the other hand, with twinkling eyes was thoroughly enjoying the scene.

"Ah, it is magnificent!" he cried. "It can be seen-Madame has a temperament."

"I am an artist," said Mirelle; "every artist has a temperament. I told Dereek to beware, and he would not listen." She whirled round on Poirot suddenly. "It is true, is it not, that he wants to marry that English miss?"

Poirot coughed.

"On m'a dit," he murmured, "that he adores her passionately." I Mirelle came towards them.

"He murdered his wife," she screamed.

"There-now you have it! He told me beforehand that he meant to do it. He had got to an impasse-zut! he took the easiest way out."

"You say that M. Kettering murdered his wife."

"Yes, yes, yes. Have I not told you so?"

"The police," murmured Poirot, "will need proof of that-er-statement."

"I tell you I saw him come out of her compartment that night on the train."

"When?" asked Poirot sharply.

"Just before the train reached Lyons."

"You will swear to that. Mademoiselle?"

It was a different Poirot who spoke now, sharp and decisive.

"Yes." There was a moment's silence. Mirelle was panting, and her eyes, half defiant, half frightened, went from the face of one man to the other.

"This is a serious matter, Mademoiselle," said the detective. "You realize how serious?"

"Certainly I do."

"That is well," said Poirot. "Then you understand. Mademoiselle, that no time must be lost. You will, perhaps accompany us immediately to the office of the Examining Magistrate."

Mirelle was taken aback. She hesitated, but, as Poirot had foreseen, she had no loophole for escape.

"Very well," she muttered. "I will fetch a coat."

Left alone together, Poirot and Knighton exchanged glances.

"It is necessary to act while-how do you say it?- the iron is hot," murmured Poirot.

"She is temperamental; in an hour's time, maybe, she will repent, and she will wish to draw back. We must prevent that at all costs."
