Katherine read this characteristic epistle through twice, then she laid it down and stared out of her bedroom window across the blue waters of the Mediterranean. She felt a curious lump in her throat. A sudden wave of longing for St. Mary Mead swept over her. So full of familiar, everyday, stupid little things—and yet—home. She felt very inclined to lay her head down on her arms and indulge in a real good cry.
Lenox, coming in at the moment, saved her.
“Hello, Katherine,” said Lenox. “I say—what is the matter?”
“Nothing,” said Katherine, grabbing up Miss Viner’s letter and thrusting it into her handbag.
“You looked rather queer,” said Lenox. “I say—I hope you don’t mind—I rang up your detective friend, M. Poirot, and asked him to lunch with us in Nice. I said you wanted to see him, as I thought he might not come for me.”
“Did you want to see him then?” asked Katherine.
“Yes,” said Lenox. “I have rather lost my heart to him. I never met a man before whose eyes were really green like a cat’s.”
“All right,” said Katherine. She spoke listlessly. The last few days had been trying. Derek Kettering’s arrest had been the topic of the hour, and the Blue Train Mystery had been thrashed out from every conceivable standpoint.
“I have ordered the car,” said Lenox, “and I have told Mother some lie or other—unfortunately I can’t remember exactly what; but it won’t matter, as she never remembers. If she knew where we were going, she would want to come too, to pump M. Poirot.”
The two girls arrived at the Negresco to find Poirot waiting.
He was full of Gallic politeness, and showered so many compliments upon the two girls that they were soon helpless with laughter; yet for all that the meal was not a gay one. Katherine was dreamy and distracted, and Lenox made bursts of conversation, interspersed by silences. As they were sitting on the terrace sipping their coffee she suddenly attacked Poirot bluntly.
“How are things going? You know what I mean?”
Poirot shrugged his shoulders. “They take their course,” he said.
“And you are just letting them take their course?”
He looked at Lenox a little sadly.
“You are young, Mademoiselle, but there are three things that cannot be hurried—le bon Dieu, Nature, and old people.”
“Nonsense!” said Lenox. “You are not old.”
“Ah, it is pretty, what you say there.”
“Here is Major Knighton,” said Lenox.
Katherine looked round quickly and then turned back again.
“He is with Mr. Van Aldin,” continued Lenox. “There is something I want to ask Major Knighton about. I won’t be a minute.”
Left alone together, Poirot bent forward and murmured to Katherine:
“You are distraite, Mademoiselle; your thoughts, they are far away, are they not?”
“Just as far as England, no farther.”
Guided by a sudden impulse, she took the letter she had received that morning and handed it across to him to read.
“That is the first word that has come to me from my old life; somehow or other—it hurts.”
He read it through and then handed it back to her.
“So you are going back to St. Mary Mead?” he said.
“No, I am not,” said Katherine; “why should I?”
“Ah,” said Poirot, “it is my mistake. You will excuse me one little minute.”
He strolled across to where Lenox
