The Mystery of the Blue Train - Agatha Christie [74]
“You want me to tell Katherine that?” asked Lenox. She breathed rather hard, as though she had been running; her face, Poirot thought, looked white and strained—rather noticeably so.
“If you please, Mademoiselle.”
“Why?” said Lenox. “Do you think Katherine will be upset? Do you think she cares?”
“I don’t know, Mademoiselle,” said Poirot. “See, I admit it frankly. As a rule I know everything, but in this case, I—well, I do not. You, perhaps, know better than I do.”
“Yes,” said Lenox, “I know—but I am not going to tell you all the same.”
She paused for a minute or two, her dark brows drawn together in a frown.
“You believe he did it?” she said abruptly.
Poirot shrugged his shoulders.
“The police say so.”
“Ah,” said Lenox, “hedging, are you? So there is something to hedge about.”
Again she was silent, frowning. Poirot said gently:
“You have known Derek Kettering a long time, have you not?”
“Off and on ever since I was a kid,” said Lenox gruffly. Poirot nodded his head several times without speaking.
With one of her brusque movements Lenox drew forward a chair and sat down on it, her elbows on the table and her face supported by her hands. Sitting thus, she looked directly across the table at Poirot.
“What have they got to go on?” she demanded. “Motive, I suppose. Probably came into money at her death.”
“He came into two million.”
“And if she had not died he would have been ruined?”
“Yes.”
“But there must have been more than that,” persisted Lenox. “He travelled by the same train, I know, but—that would not be enough to go on by itself.”
“A cigarette case with the letter ‘K’ on it which did not belong to Mrs. Kettering was found in her carriage, and he was seen by two people entering and leaving the compartment just before the train got into Lyons.”
“What two people?”
“Your friend Miss Grey was one of them. The other was Mademoiselle Mirelle, the dancer.”
“And he, Derek, what has he got to say about it?” demanded Lenox sharply.
“He denies having entered his wife’s compartment at all,” said Poirot.
“Fool!” said Lenox crisply, frowning. “Just before Lyons, you say? Does nobody know when—when she died?”
“The doctors’ evidence necessarily cannot be very definite,” said Poirot; “they are inclined to think that death was unlikely to have occurred after leaving Lyons. And we know this much, that a few moments after leaving Lyons Mrs. Kettering was dead.”
“How do you know that?”
Poirot was smiling rather oddly to himself.
“Someone else went into her compartment and found her dead.”
“And they did not rouse the train?”
“No.”
“Why was that?”
“Doubtless they had their reasons.”
Lenox looked at him sharply.
“Do you know the reason?”
“I think so—yes.”
Lenox sat still turning things over in her mind. Poirot watched her in silence. At last she looked up. A soft colour had come into her cheeks and her eyes were shining.
“You think someone on the train must have killed her, but that need not be so at all. What is to stop anyone swinging themselves on to the train when it stopped at Lyons? They could go straight to her compartment, strangle her, and take the rubies and drop off the train again without anyone being the wiser. She may have been actually killed while the train was in Lyons station. Then she would have been alive when Derek went in, and dead when the other person found her.”
Poirot leant back in his chair. He drew a deep breath. He looked across at the girl and nodded his head three times, then he heaved a sigh.
“Mademoiselle,” he said, “what you have said there is very just—very true. I was struggling in the darkness, and you have shown me a light. There was a point that puzzled me and you have made it plain.”
He got up.
“And Derek?” said Lenox.
“Who knows?” said Poirot, with a shrug of his shoulders. “But I will tell you this, Mademoiselle. I am not satisfied; no, I, Hercule Poirot, am not yet satisfied. It may be that this very night I shall learn something more. At least, I go to try.”
“You are meeting someone?”
“Yes.”
“Someone who knows something?”
“Someone
