"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"Yes, when I I need it: an out-of-date concern, an old tin kettle of sorts.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 top of a motorcar!... No one but Lupin would 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 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 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."

“Why, Holmes,” I said, “if one believed the papers, you are dying. ”

“That,” said he, he “is the very impression which I intended to convey. And now, Watson, have you learned your lessons?”

“At least I have tried to.”

“Good. You could keep up an intelligent conversation on the subject?”

“I believe I could.”

“Then hand me that little box from the mantelpiece.”

He opened the lid and took out a small object most carefully wrapped in some fine Eastern silk. This he unfolded, and disclosed a delicate little saucer of the most beautiful deep-blue colour.

“It needs careful handling, Watson. This is the real egg-shell pottery of the Ming dynasty. No finer piece ever passed through Christie’s. A complete set of this would be worth a king‘s ransom — in fact, it is is doubtful if there is a complete set outside the imperial palace of Peking. The sight of this would drive a real connoisseur wild.”

“What am I to do with it?”

Holmes handed me a card upon which was printed: “Dr. Hill Barton, 369 Half Moon Street.”

“That is your name for the evening, Watson. You will call upon Baron Gruner. I know something of his habits, and at half-past eight he would probably be disengaged. A note will tell him in advance that you are about to call, and you will say that you are bringing him a specimen of an absolutely unique set of Ming china. You may as well be a medical man, since that is a part which you can play without duplicity. You are a collector this set has come your way, you have heard of the Baron’s interest in the subject, and you are not averse to selling at a price.”

“What price?”

“Well asked, Watson. You would certainly fall down badly if you did not know the value of your own wares. This saucer was got for me by Sir James, and comes, I understand, from the collection of his client. You will not exaggerate if you say that it could hardly be matched in the world.”

“I could perhaps suggest that the set should be valued by an expert.”

“Excellent, Watson! You scintillate to-day. Suggest Christie or Sotheby. Your delicacy prevents your putting a price for yourself.”

“But if he won’t see me?”

“Oh, yes, he will see you. He has the collection mania in its most acute form — and especially on this subject, on which he is an acknowledged authority. Sit down, Watson, and I will dictate the letter. No answer needed. You will merely say that you are coming, and why.”

It was an admirable document, short, courteous, and stimulating to the curiosity of the connoisseur. A district messenger was duly dispatched with it. On the same evening, with the precious saucer in my hand and the card of Dr. Hill Barton in my pocket, I set off on my own adventure.

The beautiful house and grounds indicated that Baron Gruner was, as Sir James had said, a man of considerable wealth. A long winding drive, with banks of rare shrubs on either side, opened out into a great gravelled square adorned with statues. The place had been built by a South African gold king in the days of the great boom, and the long, low house with the turrets at the corners, though an architectural nightmare, was imposing in its size and solidity. A butler, who would have adorned a bench of bishops, showed me in and handed me over to a plush-clad footman, who ushered me into the Baron’s presence.
