The Mystery of the Blue Train

Poirot arrested the movement he was about to make.

"Is it wise what you are about to do there?" he asked warningly. His eyes shone ^ttly with a green light in them. But Derek was past noticing the warning signs. In his anger he was completely off his guard.

"I have broken with her utterly, and she knows it," cried Derek angrily.

"You have broken with her, yes, but has she broken with you?"

Derek gave a sudden harsh laugh.

"She won't break with two million pounds if she can help it," he murmured brutally; "trust Mirelle for that."

Poirot raised his eyebrows.

"You have the outlook cynical," he murmured.

"Have I?" There was no mirth in his sudden wide smile. "I have lived in the world long enough, M. Poirot, to know that all women are pretty much alike." His face softened suddenly. "All save one."

He met Poirofs gaze defiantly. A look of alertness crept into his eyes, then faded again. "That one," he said, and jerked his head in the direction of Cap Martin.

"Ah!" said Poirot.

This quiescence was well calculated to provoke the impetuous temperament of the other.

"I know what you are going to say," said Derek rapidly, "the kind of life I have led, the fact that I am not worthy of her. You will say that I have no right to think even of such a thing. You will say that it is not a case of giving a dog a bad name-I know that it is not decent to be speaking like this with my wife dead only a few days, and murdered at that."

He paused for breath, and Poirot took advantage of the pause to remark in his plaintive tone.

"But, indeed, I have not said anything at all."

"But you will."

"Eh?" said Poirot.

"You will say that I have no earthly chance of marrying Katherine."

"No," said Poirot, "I would not say that.

Your reputation is bad, yes, but with women-never does that deter them. If you were a man of excellent character, of strict morality who had done nothing that he should not do, and-possibly everything that he should do-eh bien! then I should have grave doubts of your success. Moral worth, you understand, it is not romantic.

It is appreciated, however, by widows."

Derek Kettering stared at him, then he swung round on his heel and went up to the waiting car.

Poirot looked after him with some interest He saw the lovely vision lean out of the car and speak.

Derek Kettering did not stop. He lifted his hat and passed straight on.

"Qa y est," said M. Hercule Poirot, "it is time, I think, that I return chez moi."

He found the imperturbable George pressing trousers.

"A pleasant day, Georges, somewhat fatiguing, but not without interest," he said.

George received these remarks in his usual wooden fashion.

"Indeed, sir."

"The personality of a criminal, Georges, is an interesting matter. Many murderers are men of great personal charm."

"I always heard, sir, that Dr. Crippen was a pleasant-spoken gentleman. And yet he cut up his wife like so much mincemeat."

"Your instances are always apt, Georges."

The valet did not reply, and at that moment the telephone rang. Poirot took up the receiver. («'Allo-'allo-yes, yes, it is Hercule Poirot who speaks."

"This is Knighton. Will you hold the line a minute, M. Poirot? Mr. Van Aldin would like to speak to you."

There was a moment's pause, then the millionaire's voice came through.

"Is that you, M. Poirot? I just wanted to tell you Ada Mason came to me now of her own accord. She has been thinking it over, and she says that she is almost certain that the man at Paris was Derek Kettering. There was something familiar about him at the time, she says, but at the minute she could not place it. She seems pretty certain now."

"Ah," said Poirot, "thank you, M. Van Aldin. That advances us."

He replaced the receiver, and stood for a minute or two with a very curious smile on his face. George had to speak to him twice before obtaining an answer.

"Eh?" said Poirot. "What is that that you say to me?"

"Are you lunching here, sir, or are you going out?"

"Neither," said Poirot, "I shall go to bed and take a tisane. The expected has happened, and when the expected happens, it always causes me emotion."

Chapter 25. Defiance

As Derek Kettering passed the car, Mirelle leant out.

"Dereek-I must speak to you for a moment-"

But, lifting his hat, Derek passed straight on without stopping.

When he got back to his hotel, the concierge detached himself from his wooden pen and accosted him.

"A gentleman is waiting to see you, Monsieur."

"Who is it?" asked Derek.

"He did not give me his name. Monsieur, but he said his business with you was important, and that he would wait."

"Where is he?"

"In the little salon. Monsieur. He preferred it to the lounge he said, as being more private." Derek nodded, and turned his steps in that direction.

The small salon was empty except for the visitor, who rose and bowed with easy foreign grace as Derek entered. As it chanced, Derek had only seen the Comte de la Roche once, but found no difficulty in recognizing that aristocratic nobleman, and he frowned angrily. Of all the consummate impertinence!
