"Yes, you had to see Mme. Mergy home."

"Just so, and to look after her. You can understand the poor thing's despair... Her son Gilbert so near death... And such a death!... At that time we could only hope for a miracle... an impossible miracle. I myself was resigned to the inevitable... You know as well as I do, when fate shows itself implacable, one ends by despairing."

"But I thought," observed Prasville, "that your intention, on leaving me, was to drag Daubrecq's secret from him at all costs."

"Certainly. But Daubrecq was not in Paris."

"Oh?"

"No. He was on his way to Paris in a motor-car."

"Have you a motor-car, M. Nicole?"

"Yes, when I need it: an out-of-date concern, an old tin kettle of sorts. Well, he was on his way to Paris in a motor-car, or rather on the roof of a motor-car, inside a trunk in which I packed him. But, unfortunately, the motor was unable to reach Paris until after the execution. Thereupon... "

Prasville stared at M. Nicole with an air of stupefaction. If he had retained the least doubt of the individual's real identity, this manner of dealing with Daubrecq would have removed it. By Jingo! To pack a man in a trunk and pitch him on the the top of a motorcar!... No one but Lupin would indulge in such a freak, no one but Lupin would confess it with that ingenuous coolness!

"Thereupon," echoed Prasville, "you decided what?"

"I cast about for another method."

"What method?"

"Why, surely, monsieur le secretaire-genera1, you know as well as I do!"

"How do you mean?"

"Why, weren't you at the execution?"

"I was."

"In that case, you saw both Vaucheray and the executioner bit, one mortally, the other with a slight wound. And you can't fail to see... "

"Oh," exclaimed Prasville, dumbfounded, "you confess it? It was you who fired the shots, this morning?"

"Come, monsieur le secretaire-general, think! What choice had I? The list of the Twenty-seven which you examined was a forgery. Daubrecq, who possessed the genuine one, would not arrive until a few hours after the execution. There was therefore but one way for me to save Gilbert and obtain his pardon; and that was to delay the execution by a few hours."

"Obviously."

"Well, of course. By killing that infamous brute, that hardened criminal, Vaucheray, and wounding the executioner, I spread disorder and panic; I made Gilbert's execution physically and morally impossible; and I thus gained the few hours which were indispensable for my purpose."

"Obviously," repeated Prasville.

"Well, of course," repeated Lupin, "it gives us all - the government, the president and myself - time to reflect and to see the question in a clearer light. What do you think of it, monsieur le secretaire-general?"

Prasville thought a number of things, especially that this Nicole was giving proof, to use a vulgar phrase, of the most infernal cheek, of a cheek so great that Prasville felt inclined to ask himself if he was really right in identifying Nico1e with Lupin and Lupin with Nicole.

"I think, M. Nicole, that a man has to be a jolly good shot to kill a person whom he wants to kill, at a distance of a hundred yards, and to wound another person whom he only wants to wound."

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 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.
