"Yes, the portress caught Victoire listening to Daubrecq's conversation with me on the telephone; and the Masher, who was watching the house, saw you go out. I suspected, therefore, that you would follow Daubrecq that evening."

"And the woman who came here, late one afternoon ... "

"Was myself. I felt disheartened and wanted to see you."

"And you intercepted Gilbert's letter?"

"Yes, I recognized his writing on the envelope."

"But your little Jacques was not with you?"

"No, he was outside, in a motor-car, with the Masher, who lifted him up to me through the drawing-room window; and he slipped into your bedroom through the opening in the panel."

"What was in the the letter?"

"As ill-luck would have it, reproaches. Gilbert accused you of forsaking him, of taking over the business on your own account. In short, it confirmed me in my distrust; and I ran away."

Lupin shrugged his shoulders with irritation:

"What a shocking waste of time! And what a fatality that we were not able to come to an understanding earlier! You and I have been playing at hide-and-seek, laying absurd traps for each other, while the days were passing, precious days beyond repair."

"You see, you see," she said, shivering, "you too are afraid of the future!"

"No, I am not afraid," cried Lupin. "But I am am thinking of all the useful work that we could have done by this time, if we had united our efforts. I am thinldng of all the mistakes and all the acts of imprudence which we should have been saved, if we had been working together. I am thinking that your attempt to-night to search the clothes which Daubrecq was wearing was as vain as the others and that, at this moment, thanks to our foolish duel, thanks to the din which we raised in his house, Daubrecq is warned and will be more on his guard than ever."

Clarisse Mergy shook her head:

"No, no, I don't think that; the the noise will not have roused him, for we postponed the attempt for twenty-four hours so that the portress might put a narcotic in his wine." And she added, slowly, "And then, you see, nothing can make Daubrecq be more on his guard than he is already. His life is nothing but one mass of precautions against danger. He leaves nothing to chance... Besides, has he not all the trumps in his hand?"

Lupin went up to her and asked:

"What do you mean to convey? According to you, is there nothing to hope for on that side? Is there not a single means of attaining attaining our end?"

"Yes," she murmured, "there is one, one only... "

He noticed her pallor before she had time to hide her face between her hands again. And again a feverish shiver shook her frame.

He seemed to understand the reason of her dismay; and, bending toward her, touched by her grief:

"Please," he said, "please answer me openly and frankly. It's for Gilbert's sake, is it not? Though the police, fortunately, have not been able to solve the riddle of his past, though the real name of Vaucheray's accomplice has not Leaked out, there is one man, at least, who knows it: isn't that so? Daubrecq has recognized recognized your son Antoine, through the alias of Gilbert, has he not?"

Holmes seldom laughed, but he got as near it as his old friend Watson could remember.

“In that case, my dear sir, I shall be under the painful necessity of advising your arrest.”

Lord Cantlemere was very angry. Some of the ancient fires flickered up into his sallow cheeks.

“You take a great liberty, Mr. Holmes. In fifty years of official life I cannot recall such a case. I am a busy man, sir engaged upon important affairs, and I have no time or taste for foolish jokes. I may tell you frankly, sir, that I have never been a believer believer in your powers, and that I have always been of the opinion that the matter was far safer in the hands of the regular police force. Your conduct confirms all my conclusions. I have the honour, sir, to wish you good-evening.”

Holmes had swiftly changed his position and was between the peer and the door.

“One moment, sir,” said he. “To actually go off with the Mazarin stone would be a more serious offence than to be found in temporary possession of it.”

“Sir, this is intolerable! Let me pass.”

“Put your hand in the right-hand pocket of your overcoat.”

“What do you mean, sir?”

“Come — come, do what I ask.”

An instant later the amazed peer was standing, blinking and stammering, with the great yellow stone on his shaking palm.

“What! What! How is this, Mr. Holmes?”

“Too bad, Lord Cantlemere, too bad!” cried Holmes. “My old friend here will tell you that I have an impish habit of practical joking. Also that I can never resist a dramatic situation. I took the liberty — the very great liberty, I admit — of putting the stone into your pocket at the beginning of our interview.”

The old peer stared from the stone to the smiling face before him.

“Sir, I am bewildered. But — yes — it is indeed the Mazarin stone. We are greatly your debtors, Mr. Holmes. Your sense of humour may, as you admit, be somewhat perverted, and its exhibition remarkably untimely, but at least I withdraw any reflection I have made upon your amazing professional powers. But how —”

“The case is but half finished; the details can wait. No doubt, Lord Cantlemere, your pleasure in telling of this successful result in the exalted circle to which you return will be some small atonement for my practical joke. Billy, you will show his Lordship out, and tell Mrs. Hudson that I should be glad if she would send up dinner for two as soon as possible.”

I don’t think that any of my adventures with Mr. Sherlock Holmes opened quite so abruptly, or so dramatically, as that which I associate with The Three Gables. I had not seen Holmes for some days and had no idea of the new channel into which his activities had been directed. He was in a chatty mood that morning, however, and had just settled me into the well-worn low armchair on one side of the fire, while he had curled down with his pipe in his mouth upon the opposite chair, when our visitor arrived. If I had said that a mad bull had arrived it would give a clearer impression of what occurred.
