brain marches to a marvel, my friend! Figure to yourself that for the moment I had not thought of that! But there is plenty of time. The full of the moon, it is not until Friday.”
I shook my head dubiously. The full of the moon theory left me entirely cold. I had my way with Poirot, however, and we departed immediately, leaving behind us a note of explanation and apology for Lord Yardly.
My idea was to go at once to the Magnificent, and relate to Miss Marvell what had occurred, but Poirot vetoed the plan, and insisted that the morning would be time enough. I gave in rather grudgingly.
In the morning Poirot seemed strangely disinclined to stir out. I began to suspect that, having made a mistake to start with, he was singularly loath to proceed with the case. In answer to my persuasions, he pointed out, with admirable common sense, that as the details of the affair at Yardly Chase were already in the morning papers the Rolfs would know quite as much as we could tell them. I gave way unwillingly.
Events proved my forebodings to be justified. About two o’clock, the telephone rang. Poirot answered it. He listened for some moments, then with a brief “Bien, j’y serai” he rang off, and turned to me.
“What do you think, mon ami?” He looked half ashamed, half excited. “The diamond of Miss Marvell, it has been stolen.”
“What?” I cried, springing up. “And what about the ‘full of the moon’ now?” Poirot hung his head. “When did this happen?”
“This morning, I understand.”
I shook my head sadly. “If only you had listened to me. You see I was right.”
“It appears so, mon ami,” said Poirot cautiously. “Appearances are deceptive, they say, but it certainly appears so.”
As we hurried in a taxi to the Magnificent, I puzzled out the true inwardness of the scheme.
“That ‘full of the moon’ idea was clever. The whole point of it was to get us to concentrate on the Friday, and so be off our guard beforehand. It is a pity you did not realize that.”
“Ma foi!” said Poirot airily, his nonchalance quite restored after its brief eclipse. “One cannot think of everything!”
I felt sorry for him. He did so hate failure of any kind.
“Cheer up,” I said consolingly. “Better luck next time.”
At the Magnificent, we were ushered at once into the manager’s office. Gregory Rolf was there with two men from Scotland Yard. A pale-faced clerk sat opposite them.
Rolf nodded to us as we entered.
“We’re getting to the bottom of it,” he said. “But it’s almost unbelievable. How the guy had the nerve I can’t think.”
A very few minutes sufficed to give us the facts. Mr. Rolf had gone out of the hotel at 11.15. At 11.30, a gentleman, so like him in appearance as to pass muster, entered the hotel and demanded the jewel-case from the safe deposit. He duly signed the receipt, remarking carelessly as he did so: “Looks a bit different from my ordinary one, but I hurt my hand getting out of the taxi.” The clerk merely smiled and remarked that he saw very little difference. Rolf laughed and said: “Well, don’t run me in as a crook this time, anyway. I’ve been getting threatening letters from a Chinaman, and the worst of it is I look rather like a Chink myself—it’s something about the eyes.”
“I looked at him,” said the clerk who was telling us this, “and I saw at once what he meant. The eyes slanted up at the corners like an Oriental’s. I’d never noticed it before.”
“Darn it all, man,” roared Gregory Rolf, leaning forward, “do you notice it now?”
The man looked up at him and started.
“No, sir,” he said. “I can’t say I do.” And indeed there was nothing even remotely Oriental about the frank brown eyes that looked into ours.
The Scotland Yard man grunted. “Bold customer. Thought the eyes might be noticed, and took the bull by the horns to disarm suspicion. He must have watched you out of the hotel, sir, and nipped in as soon as you were well away.”
“What about the jewel-case?” I asked.
“It was found in a corridor of the hotel. Only one thing had been taken—‘the Western Star.’”
We stared at each other—the whole thing was so bizarre, so unreal.
Poirot hopped briskly to his feet. “I have not been of much use, I fear,” he said regretfully. “Is it permitted to see Madame?”
“I guess she’s prostrated with the shock,” explained Rolf.
“Then perhaps I might have a few words alone with you, monsieur?”
“Certainly.”
In about five minutes Poirot reappeared.
“Now, my friend,” he said gaily. “To a post office. I have to send a telegram.”
“Who to?”
“Lord Yardly.” He discounted further inquiries by slipping his arm through mine. “Come, come, mon ami. I know all that you feel about this miserable business. I have not distinguished myself! You, in my place, might have distinguished yourself! Bien! All is admitted. Let us forget it and have lunch.”
It was about four o’clock when we entered Poirot’s rooms. A figure rose from a chair by the window. It was Lord Yardly. He looked haggard and distraught.
“I got your wire and came up at once. Look here, I’ve been round to Hoffberg, and they know nothing about that man of theirs last night, or the wire either. Do you think that——”
Poirot held up his hand.
“My excuses! I sent that wire, and hired the gentleman in question.”
“You—but why? What?” The nobleman spluttered impotently.
“My little idea was to bring things to a head,” explained Poirot placidly.
“Bring things to a head! Oh, my God!” cried Lord Yardly.
“And the ruse succeeded,” said Poirot cheerfully. “Therefore, milord, I have much pleasure in returning you—this!” With a dramatic gesture he produced a glittering object. It was a great diamond.
“The Star of the East,” gasped Lord Yardly. “But I don’t understand——”
“No?” said Poirot. “It makes no matter. Believe me, it was necessary for the diamond to be stolen. I promised you that it should be preserved to you, and I have kept my word. You must permit me to keep my little secret. Convey, I beg of you, the assurances of my deepest respect to Lady Yardly, and tell her how pleased I am to be able to restore her jewel to her. What beau temps, is it not? Good day, milord.”
And smiling and talking, the amazing little man conducted the bewildered nobleman to the door. He returned gently rubbing his hands.
“Poirot,”
