The Mystery of the Blue Train by Agatha Christie
“But there is one thing I do not understand, Monsieur Poirot. I guess I must be dense or I would have seen it before now. Who was the man in the train at Paris? Derek Kettering or the Comte de la Roche?”
“That is the simplicity of the whole thing. There was no man. Ah—mille tonnerres!—do you not see the cleverness of it all? Whose word have we for it that there ever was a man there? Only Ada Mason’s. And we believe in Ada Mason because of Knighton’s evidence that she was left behind in Paris.”
“But Ruth herself told the conductor that she had left her maid behind there,” demurred Van Aldin.
“Ah! I am coming to that. We have Mrs. Kettering’s own evidence there, but, on the other hand, we have not really got her evidence, because, Monsieur Van Aldin, a dead woman cannot give evidence. It is not her evidence, but the evidence of the conductor of the train—a very different affair altogether.”
“So you think the man was lying?”
“No, no, not at all. He spoke what he thought to be the truth. But the woman who told him that she had left her maid in Paris was not Mrs. Kettering.”
Van Aldin stared at him.
“Monsieur Van Aldin, Ruth Kettering was dead before the train arrived at the Gare de Lyon. It was Ada Mason, dressed in her mistress’s very distinctive clothing, who purchased a dinner basket and who made that very necessary statement to the conductor.”
“Impossible!”
“No, no, Monsieur Van Aldin; not impossible. Les femmes, they look so much alike nowadays that one identifies them more by their clothing than by their faces. Ada Mason was the same height as your daughter. Dressed in that very sumptuous fur coat and the little red lacquer hat jammed down over her eyes, with just a bunch of auburn curls showing over each ear, it was no wonder that the conductor was deceived. He had not previously spoken to Mrs. Kettering, you remember. True, he had seen the maid just for a moment when she handed him the tickets, but his impression had been merely that of a gaunt, black-clad female. If he had been an unusually intelligent man, he might have gone so far as to say that mistress and maid were not unlike, but it is extremely unlikely that he would even think that. And remember, Ada Mason, or Kitty Kidd, was an actress, able to change her appearance and tone of voice at a moment’s notice. No, no; there was no danger of his recognizing the maid in the mistress’s clothing, but there was the danger that when he came to discover the body he might realize it was not the woman he had talked to the night before. And now we see the reason for the disfigured face. The chief danger that Ada Mason ran was that Katherine Grey might visit her compartment after the train left Paris, and she provided against that difficulty by ordering a dinner basket and by locking herself in her compartment.”
“But who killed Ruth—and when?”
“First, bear it in mind that the crime was planned and undertaken by the two of them—Knighton and Ada Mason, working together. Knighton was in Paris that day on your business. He boarded the train somewhere on its way round the ceinture. Mrs. Kettering would be surprised, but she would be quite unsuspicious. Perhaps he draws her attention to something out of the window, and as she turns to look he slips the cord round her neck—and the whole thing is over in a second or two. The door of the compartment is locked, and he and Ada Mason set to work. They strip off the dead woman’s outer clothes. Mason and Knighton roll the body up in a rug and put it on the seat in the adjoining compartment amongst the bags and suitcases. Knighton drops off the train, taking the jewel case containing the rubies with him. Since the crime is not supposed to have been committed until nearly twelve hours later he is perfectly safe, and his evidence and the supposed Mrs. Kettering’s words to the conductor will provide a perfect alibi for his accomplice.
“At the Gare de Lyon Ada Mason gets a dinner basket and, shutting herself into the toilet compartment, she quickly changes into her mistress’s clothes, adjusts two false bunches of auburn curls, and generally makes up to resemble her as closely as possible. When the conductor comes to make up the bed, she tells him the prepared story about having left her maid behind in Paris; and whilst he is making up the berth, she stands looking out of the window, so that her back is towards the corridor and people passing along there. That was a wise precaution, because, as we know, Miss Grey was one of those passing, and she, among others, was willing to swear that Mrs. Kettering was still alive at that hour.”
“Go on,” said Van Aldin.
“Before getting to Lyons, Ada Mason arranged her mistress’s body in the bunk, folded up the dead woman’s clothes neatly on the end of it, and herself changed into a man’s clothes and prepared to leave the train. When Derek Kettering entered his wife’s compartment, and, as he thought, saw her asleep in her berth, the scene had been set, and Ada Mason was hidden in the next compartment waiting for the moment to leave the train unobserved. As soon as the conductor had swung himself down on to the platform at Lyons, she follows, slouching along as though just taking a breath of air. At a moment when she is unobserved, she hurriedly crosses to the other platform, and takes the first train back to Paris and the Ritz Hotel. Her name has been registered there as taking a room the night before by one of Knighton’s female accomplices. She has nothing to do but wait there placidly for your arrival. The jewels are not, and never have been, in her possession. No suspicion attaches to him, and, as your secretary, he brings them to Nice without the least fear of discovery. Their delivery there to Monsieur Papopolous is already arranged for, and they are entrusted to Mason at the last moment to hand over to the Greek. Altogether a very neatly planned coup, as one would expect from a master of the game such as the Marquis.”
“And you honestly mean that Richard Knighton is a well-known criminal, who has been at this business for years?”
Poirot nodded.
“One of the chief assets of the gentleman called the Marquis was his plausible, ingratiating manner. You fell a victim of his charm, Monsieur Van Aldin, when you engaged him as a secretary on such a slight acquaintanceship.”
“I could have sworn that he never angled for the post,” cried the millionaire.
“It was very astutely done—so astutely done that it deceived a man whose knowledge of other men is as great as yours is.”
“I looked up his antecedents too. The fellow’s record was excellent.”
“Yes, yes; that was part of the game. As Richard Knighton his life was quite free from reproach. He was well-born, well-connected, did honourable service in the War, and seemed altogether above suspicion; but when I came to glean information about the mysterious Marquis, I found many points of similarity. Knighton spoke French like a Frenchman, he had been in America, France, and England at much the same time as the Marquis was operating. The Marquis was last heard of as engineering various jewel robberies in Switzerland, and it was in Switzerland that you had come across Major Knighton; and it was at precisely that time that the first rumours were going round of your being in treaty for the famous rubies.”
“But why murder?” murmured Van Aldin brokenly. “Surely a clever thief could have stolen the jewels without running his head into a noose.”
Poirot shook his head. “This is not the first murder that lies to the Marquis’s charge. He is a killer by instinct; he believes, too, in leaving no evidence behind him. Dead men and women tell no tales.
“The Marquis had an intense passion for famous and historical jewels. He laid his plans far beforehand by installing himself as your secretary and getting his accomplice to obtain the situation of maid with your daughter, for whom he guessed the jewels were destined. And, though this was his matured and carefully thought-out plan, he did not scruple to attempt a short-cut by hiring a couple of apaches to waylay you in Paris on the night you bought the jewels. The plan failed, which hardly surprised him, I think. This plan was, so he thought, completely safe. No possible suspicion could attach to Richard Knighton. But like all great men—and the Marquis was a great man—he had his weaknesses. He fell genuinely in love with Miss Grey, and, suspe
“Extraordinary,” said Van Aldin.
“Yes, it is very strange. One cannot explain these things. Oh, by the way, there is one little point that baffled me considerably. Your secretary has a decided limp—the result of a wound that he received in the War. Now the Marquis most decidedly did not limp. That was a stumbling block. But Miss Lenox Tamplin happened to mention one day that Knighton’s limp had been a surprise to the surgeon who had been in charge of the case in her mother’s hospital. That suggested camouflage. When I was in London I went to the surgeon in question, and I got several technical details from him which confirmed me in that belief. I mentioned the name of that surgeon in Knighton’s hearing the day before yesterday. The natural thing would have been for Knighton to mention that he had been attended by him during the War, but he said nothing—and that little point, if nothing else, gave me the last final assurance that my theory of the crime was correct. Miss Grey, too, provided me with a cutting, showing that there had been a robbery at Lady Tamplin’s hospital during the time that Knighton had been there. She realized that I was on the same track as herself when I wrote to her from the Ritz in Paris.
“I had some trouble in my inquiries there, but I got what I wanted—evidence that Ada Mason arrived on the morning after the crime and not on the evening of the day before.”
There was a long silence, then the millionaire stretched out a hand to Poirot across the table.
“I guess you know what this means to me, Monsieur Poirot,” he said huskily. “I am sending you round a cheque in the morning, but no cheque in the world will express what I feel about what you have done for me. You are the goods, Monsieur Poirot. Every time, you are the goods.”
Poirot rose to his feet; his chest swelled.
“I am only Hercule Poirot,” he said modestly, “yet, as you say, in my own way I am a big man, even as you also are a big man. I am glad and happy to have been of service to you. Now I go to repair the damages caused by travel. Alas! My excellent Georges is not with me.”
In the lounge of the hotel he encountered a friend—the venerable Monsieur Papopolous, his daughter Zia beside him.
“I thought you had left Nice, Monsieur Poirot,” murmured the Greek as he took the detective’s affectionately proferred hand.
“Business compelled me to return, my dear Monsieur Papopolous.”
“Business?”
“Yes, business. And talking of business, I hope your health is better, my dear friend?”
“Much better. In fact, we are returning to Paris tomorrow.”
“I am enchanted to hear such good news. You have not completely ruined the Greek ex-Minister, I hope.”
“I?”
“I understand you sold him a very wonderful ruby which—strictly entre nous—is being worn by Mademoiselle Mirelle, the dancer?”
“Yes,” murmured Monsieur Papopolous; “yes, that is so.”
“A ruby not unlike the famous ‘Heart of Fire.’ ”
“It has points of resemblance, certainly,” said the Greek casually.
“You have a wonderful hand with jewels, Monsieur Papopolous. I congratulate you. Mademoiselle Zia, I am desolate that you are returning to Paris so speedily. I had hoped to see some more of you now that my business is accomplished.”
“Would one be indiscreet if one asked what that business was?” asked Monsieur Papopolous.
“Not at all, not at all. I have just succeeded in laying the Marquis by the heels.”
A far-away look came over Monsieur Papopolous’ noble countenance.
“The Marquis?” he murmured; “now why does that seem familiar to me? No—I cannot recall it.”
“You would not, I am sure,” said Poirot. “I refer to a very notable criminal and jewel robber. He has just been arrested for the murder of the English lady, Madame Kettering.”
“Indeed? How interesting these things are!”
A polite exchange of farewells followed, and when Poirot was out of earshot, Monsieur Papopolous turned to his daughter.
“Zia,” he said, with feeling, “that man is the devil!”
“I like him.”
“I like him myself,” admitted Monsieur Papopolous. “But he is the devil, all the same.”

BY THE SEA
The mimosa was nearly over. The scent of it in the air was faintly unpleasant. There were pink geraniums twining along the balustrade of Lady Tamplin’s villa, and masses of carnations below sent up a sweet, heavy perfume. The Mediterranean was at its bluest. Poirot sat on the terrace with Lenox Tamplin. He had just finished telling her the same story that he had told to Van Aldin two days before. Lenox had listened to him with absorbed attention, her brows knitted and her eyes sombre.
When he had finished she said simply:
“And Derek?”
“He was released yesterday.”
“And he has gone—where?”
“He left Nice last night.”
“For St. Mary Mead?”
“Yes, for St. Mary Mead.”
There was a pause.
“I was wrong about Katherine,” said Lenox. “I thought she did not care.”
“She is very reserved. She trusts no one.”
“She might have trusted me,” said Lenox, with a shade of bitterness.
“Yes,” said Poirot gravely, “she might have trusted you. But Mademoiselle Katherine has spent a great deal of her life listening, and those who have listened do not find it easy to talk; they keep their sorrows and joys to themselves and tell no one.”
“I was a fool,” said Lenox; “I thought she really cared for Knighton. I ought to have known better. I suppose I thought so because—well, I hoped so.”
Poirot took her hand and gave it a little friendly squeeze. “Courage, Mademoiselle,” he said gently.
Lenox looked very straight out across the sea, and her face, in its ugly rigidity, had for the moment a tragic beauty.
“Oh, well,” she said at last, “it would not have done. I am too young for Derek; he is like a kid that has never grown up. He wants the Madonna touch.”
There was a long silence, then Lenox turned to him quickly and impulsively. “But I did help, Monsieur Poirot—at any rate I did help.”
“Yes, Mademoiselle. It was you who gave me the first inkling of the truth when you said that the person who committed the crime need not have been on the train at all. Before that, I could not see how the thing had been done.”
Lenox drew a deep breath.
“I am glad,” she said; “at any rate—that is something.”
From far behind them there came a long-drawn-out scream of an engine’s whistle.
“That is that damned Blue Train,” said Lenox. “Trains are relentless things, aren’t they, Monsieur Poirot? People are murdered and die, but they go on just the same. I am talking nonsense, but you know what I mean.”
“Yes, yes, I know. Life is like a train, Mademoiselle. It goes on. And it is a good thing that that is so.”
“Why?”
“Because the train gets to its journey’s end at last, and there is a proverb about that in your language, Mademoiselle.”
?
“Yes—yes, it is true. You are young, younger than you yourself know. Trust the train, Mademoiselle, for it is le bon Dieu who drives it.”
The whistle of the engine came again.
“Trust the train, Mademoiselle,” murmured Poirot again. “And trust Hercule Poirot—He knows.”
