"You don't want me any more at present?"
"No, Monsieur; we have all the information we need for the moment."
"Then I will walk a little way with M. Poirot. That is, if he does not object?"
"Enchanted, Monsieur," said the little man, with a bow.
Van Aldin lighted a large cigar, having first offered one to Poirot, who declined it and lit one of his own tiny cigarettes. A man of great strength of character, Van Aldin already appeared to be his everyday, normal self once more. After strolling along for a minute or two in silence, the millionaire spoke:
"I take it, M. Poirot, that you no longer exercise your profession?"
"That is so, Monsieur. I enjoy the world."
"Yet you are assisting the police in this affair?"
"Monsieur, if a doctor walks along the street and an accident happens, does he say, 'I have retired from my profession, I will continue my walk,' when there is some one bleeding to death at his feet? If I had been already in Nice, and the police had sent to me and asked me to assist them, I should have refused. But this affair, the good God thrust it upon me."
"You were on the spot," said Van Aldin thoughtfully. "You examined the compartment, did you not?"
Poirot nodded.
"Doubtless you found things that were, shall we say, suggestive to you?"
"Perhaps," said Poirot.
"I hope you see what I am leading up to?" said Van Aldin. "It seems to me that the case against this Comte de la Roche is perfectly clear, but I am not a fool. I have been watching you for this last hour or so, and I realize that for some reason of your own you don't agree with that theory?"
Poirot shrugged his shoulders.
"I may be wrong."
"So we come to the favour I want to ask you. Will you act in this matter for me?"
"For you personally?"
"That was my meaning."
Poirot was silent for a moment or two. Then he said:
"You realize what you are asking?"
"I guess so," said Van Aldin.
"Very well," said Poirot. "I accept. But in that case, I must have frank answers to my questions."
"Why, certainly. That is understood."
Poirot's manner changed. He became suddenly brusque and business-like.
"This question of a divorce," he said. "It was you who advised your daughter to bring the suit?"
"Yes."
"When?"
"About ten days ago. I had had a letter from her complaining of her husband's behaviour, and I put it to her very strongly that divorce was the only remedy."
"In what way did she complain of his behaviour?"
"He was being seen about with a _very_ notorious lady--the one we have been speaking of--Mirelle."
"The dancer. Ah-ha! And Madame Kettering objected? Was she very devoted to her husband?"
"I would not say that," said Van Aldin, hesitating a little.
"It was not her heart that suffered, it was her pride--is that what you would say?"
"Yes, I suppose you might put it like that."
"I gather that the marriage had not been a happy one from the beginning?"
"Derek Kettering is rotten to the core," said Van Aldin. "He is incapable of making any woman happy."
"He is, as you say in England, a bad lot. That is right, is it not?"
Van Aldin nodded.
"_Très bien!_ You advise Madame to seek a divorce, she agrees; you consult your solicitors. When does M. Kettering get news of what is in the wind?"
"I sent for him myself, and explained the course of action I proposed to take."
"And what did he say?" murmured Poirot softly.
Van Aldin's face darkened at the remembrance.
"He was infernally impudent."
"Excuse the question, Monsieur, but did he refer to the Comte de la Roche?"
"Not by name," growled the other unwillingly, "but he showed himself cognizant of the affair."
"What, if I may ask, was M. Kettering's financial position at the time?"
"How do you suppose I should know that?" asked Van Aldin, after a very brief hesitation.
"It seemed likely to me that you would inform yourself on that point."
"Well--you are quite right, I did. I discovered that Kettering was on the rocks."
"And now he has inherited two million pounds! _La vie_--it is a strange thing, is it not?"
Van Aldin looked at him sharply.
"What do you mean?"
"I moralize," said Poirot. "I reflect, I speak the philosophy. But to return to where we were. Surely M. Kettering did not propose to allow himself to be divorced without making a fight for it?"
Van Aldin did not answer for a minute or two, then he said:
"I don't exactly know what his intentions were."
"Did you hold any further communications with him?"
Again a slight pause, then Van Aldin said:
"No."
Poirot stopped dead, took off his hat, and held out his hand.
"I must wish you good-day, Monsieur. I can do nothing for you."
"What are you getting at?" demanded Van Aldin angrily.
"If you do not tell me the truth, I can do nothing."
"I don't know what you mean."
"I think you do. You may rest assured, M. Van Aldin, that I know how to be discreet."
"Very well, then," said the millionaire. "I'll admit that I was not speaking the truth just now. I _did_ have further communication with my son-in-law."
"Yes?"
"To be exact, I sent my secretary, Major Knighton, to see him, with instructions to offer him the sum of one hundred thousand pounds in cash if the divorce went through undefended."
"A pretty sum of money," said Poirot appreciatively; "and the answer of Monsieur your son-in-law?"
"He sent back word that I could go to hell," replied the millionaire succinctly.
"Ah!" said Poirot.
He betrayed no emotion of any kind. At the moment he was engaged in methodically recording facts.
"Monsieur Kettering has told the police that he neither saw nor spoke to his wife on the journey from England. Are you inclined to believe that statement, Monsieur?"
"Yes, I am," said Van Aldin. "He would take particular pains to keep out of her way, I should say."
"Why?"
"Because he had got that woman with him."
"Mirelle?"
"Yes."
"How did you come to know that fact?"
"A man of mine, whom I had put on to watch him, reported to me that they had both left by that train."
"I see," said Poirot. "In that case, as you said before, he would not be likely to attempt to hold any communication with Madame Kettering."
The little man fell silent for some time. Van Aldin did not interrupt his meditation.
17. An Aristocratic Gentleman
"You have been to the Riviera before, Georges?" said Poirot to his valet the following morning.
George was an intensely English, rather wooden-faced individual.
"Yes, sir. I was here two years ago when I was in the service of Lord Edward Frampton."
"And to-day," murmured his master, "you are here with Hercule Poirot. How one mounts in the world!"
The valet made no reply to this observation. After a suitable pause he asked:
"The brown lounge suit, sir? The wind is somewhat chilly to-day."
"There is a grease spot on the waistcoat," objected Poirot. "A _morceau_ of _filet de sole à la Jeannette_ alighted there when I was lunching at the Ritz last Tuesday."
"There is no spot there now, sir," said George reproachfully. "I have removed it."
"_Très bien!_" said Poirot. "I am pleased with you, Georges."
"Thank you, sir."
There was a pause, and then Poirot murmured dreamily:
"Supposing, my good Georges, that you had been born in the same social sphere as your late master, Lord Edward Frampton--that, penniless yourself, you had married an extremely wealthy wife, but that that wife proposed to divorce you, with excellent reasons, what would you do about it?"
"I should endeavour, sir," replied George, "to make her change her mind."
"By peaceful or by forcible methods?"
George looked shocked.
"You will excuse me, sir," he said, "but a gentleman of the aristocracy would not behave like a Whitechapel coster. He would not do anything low."
"Would he not, Georges? I wonder now. Well, perhaps you are right."
There was a knock on the door. George went to it and opened it a discreet inch or two. A low murmured colloquy went on, and then the valet returned to Poirot.
"A note, sir."
Poirot took it. It was from M. Caux, the Commissary of Police.
"We are about to interrogate the Comte de la Roche. The Juge d'Instruction begs that you will be present."
"Quickly, my suit, Georges! I must hasten myself."
A quarter of an hour later, spick and span in his brown suit, Poirot entered the Examining Magistrate's room. M. Caux was already there, and both he and M. Carrège greeted Poirot with polite _empressement_.
"The affair is somewhat discouraging," murmured M. Caux.
"It appears that the Comte arrived in Nice the day before the murder."
"If that is true, it will settle your affair nicely for you," responded Poirot.
M. Carrège cleared his throat.
"We must not accept this alibi without very cautious inquiry," he declared. He struck the bell upon the table with his hand.
In another minute a tall dark man, exquisitely dressed, with a somewhat haughty cast of countenance, entered the room. So very aristocratic-looking was the Count, that it would have seemed sheer heresy even to whisper that his father had been an obscure corn-chandler in Nantes--which, as a matter of fact, was the case. Looking at him, one would have been prepared to swear that innumerable ancestors of his must have perished by the guillotine in the French Revolution.
