old fellow was just the least inclined to be jealous. It had become rather a pose with him to consistently belittle my abilities, and I think he was chagrined at finding no loophole for criticism. I was secretly rather pleased with myself, though I tried to conceal the fact for fear of irritating him. In spite of his idiosyncrasies, I was deeply attached to my quaint little friend.
“Bien!” he said at length, with a curious look on his face. “The plot develops. Pass me, I pray you, that ‘Peerage’ on the top shelf there.” He turned the leaves. “Ah, here we are! ‘Yardly . . . 10th viscount, served South African War’ . . . tout ça n’a pas d’importance . . . ‘mar. 1907 Hon. Maude Stopperton, fourth daughter of 3rd Baron Cotteril’ . . . um, um, um, . . . ‘has iss. two daughters, born 1908, 1910. . . . Clubs . . . residences.’ . . . Voilà, that does not tell us much. But to-morrow morning we see this milord!”
“What?”
“Yes. I telegraphed to him.”
“I thought you had washed your hands of the case?”
“I am not acting for Miss Marvell since she refuses to be guided by my advice. What I do now is for my own satisfaction—the satisfaction of Hercule Poirot! Decidedly, I must have a finger in this pie.”
“And you calmly wire Lord Yardly to dash up to town just to suit your convenience. He won’t be pleased.”
“Au contraire, if I preserve for him his family diamond, he ought to be very grateful.”
“Then you really think there is a chance of it being stolen?” I asked eagerly.
“Almost a certainty,” replied Poirot placidly. “Everything points that way.”
“But how——”
Poirot stopped my eager questions with an airy gesture of the hand.
“Not now, I pray you. Let us not confuse the mind. And observe that ‘Peerage’—how you have replaced him! See you not that the tallest books go in the top shelf, the next tallest in the row beneath, and so on. Thus we have order, method, which, as I have often told you, Hastings——”
“Exactly,” I said hastily, and put the offending volume in its proper place.
Lord Yardly turned out to be a cheery, loud-voiced sportsman with a rather red face, but with a good-humoured bonhomie about him that was distinctly attractive and made up for any lack of mentality.
“Extraordinary business this, Monsieur Poirot. Can’t make head or tail of it. Seems my wife’s been getting odd kind of letters, and that this Miss Marvell’s had ’em too. What does it all mean?”
Poirot handed him the copy of Society Gossip.
“First, milord, I would ask you if these facts are substantially correct?”
The peer took it. His face darkened with anger as he read.
“Damned nonsense!” he spluttered. “There’s never been any romantic story attaching to the diamond. It came from India originally, I believe. I never heard of all this Chinese god stuff.”
“Still, the stone is known as ‘The Star of the East.’”
“Well, what if it is?” he demanded wrathfully.
Poirot smiled a little, but made no direct reply. “What I would ask you to do, milord, is to place yourself in my hands. If you do so unreservedly, I have great hopes of averting the catastrophe.”
“Then you think there’s actually something in these wild-cat tales?”
“Will you do as I ask you?”
“Of course I will, but——”
“Bien! Then permit that I ask you a few questions. This affair of Yardly Chase, is it, as you say, all fixed up between you and Mr. Rolf?”
“Oh, he told you about it, did he? No, there’s nothing settled.” He hesitated, the brick-red colour of his face deepening. “Might as well get the thing straight. I’ve made rather an ass of myself in many ways, Monsieur Poirot—and I’m head over ears in debt—but I want to pull up. I’m fond of the kids, and I want to straighten things up, and be able to live on at the old place. Gregory Rolf is offering me big money—enough to set me on my feet again. I don’t want to do it—I hate the thought of all that crowd play-acting round the Chase—but I may have to, unless——” He broke off.
Poirot eyed him keenly. “You have, then, another string to your bow? Permit that I make a guess? It is to sell the Star of the East?”
Lord Yardly nodded. “That’s it. It’s been in the family for some generations, but it’s not entailed. Still, it’s not the easiest thing in the world to find a purchaser. Hoffberg, the Hatton Garden man, is on the look-out for a likely customer, but he’ll have to find one soon, or it’s a washout.”
“One more question, permettez—Lady Yardly, which plan does she approve?”
“Oh, she’s bitterly opposed to my selling the jewel. You know what women are. She’s all for this film stunt.”
“I comprehend,” said Poirot. He remained a moment or so in thought, then rose briskly to his feet. “You return to Yardly Chase at once? Bien! Say no word to anyone—to anyone mind—but expect us there this evening. We will arrive shortly after five.”
“All right, but I don’t see——”
“Ça n’a pas d’importance,” said Poirot kindly. “You will that I preserve for you your diamond, n’est-ce pas?”
“Yes, but——”
“Then do as I say.”
A sadly bewildered nobleman left the room.
It was half-past five when we arrived at Yardly Chase, and followed the dignified butler to the old panelled hall with its fire of blazing logs. A pretty picture met our eyes: Lady Yardly and her two children, the mother’s proud dark head bent down over the two fair ones. Lord Yardly stood near, smiling down on them.
“Monsieur Poirot and Captain Hastings,” announced the butler.
Lady Yardly looked up with a start, her husband came forward uncertainly, his eyes seeking instruction from Poirot. The little man was equal to the occasion.
“All my excuses! It is that I investigate still this affair of Miss Marvell’s. She comes to you on Friday, does she not? I make a little tour first to make sure that all is secure. Also I wanted to ask of Lady Yardly if she recollected at all the postmarks on the letters she received?”
Lady Yardly shook her head regretfully. “I’m afraid I don’t. It is stupid of me. But, you see, I never dreamt of taking them seriously.”
“You’ll stay the night?” said Lord Yardly.
“Oh, milord, I fear to incommode you. We have left our bags at the inn.”
“That’s
