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"Yes, when I need it: an out-of-date concern, an old tin kettle of sorts.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

“It is his love diary?”

“Or his lust diary. Call it what you will. The moment the woman told us of it I realized what a tremendous weapon was there if we could but lay our hands on it. I said nothing at the time to indicate my thoughts, for this woman might have given it away. But I brooded over it. Then this assault upon me gave me the chance of letting the Baron think that no precautions need be taken against me. That was all to the good. I would have waited a little longer, but his visit to America forced my hand. He would never have left so compromising a document behind him. Therefore we had to act at once. Burglary at night is impossible. He takes precautions. But there was a chance in the evening if I could only be sure that his attention was engaged. That was where you and your blue saucer came in. But I had to be sure of the position of the book, and I knew I had only a few minutes in which to act, for my time was limited by your knowledge of Chinese pottery. Therefore I gathered the girl up at the last moment. How could I guess what the little packet was that she carried so carefully under her cloak? I thought she had come altogether on my business, but it seems she had some of her own.”

“He guessed I came from you.”

“I feared he would. But you held him in play just long enough for me to get the book, though not long enough for an unobserved escape. Ah, Sir James, I am very glad you have come!”

Our courtly friend had appeared in answer to a previous summons. He listened with the deepest attention to Holmes’s account of what had occurred.

“You have done wonders — wonders!” he cried when he had heard the narrative. “But if these injuries are as terrible as Dr. Watson describes, then surely our purpose of thwarting the marriage is sufficiently gained without the use of this horrible book.”

Holmes shook his head.

“Women of the De Merville type do not act like that. She would love him the more as a disfigured martyr. No, no. It is his moral side, not his physical, which we have to destroy. That book will bring her back to earth — and I know nothing else that could. It is in his own writing. She cannot get past it.”

Sir James carried away both it and the precious saucer. As I was myself overdue, I went down with him into the street. A brougham was waiting for him. He sprang in, gave a hurried order to the cockaded coachman, and drove swiftly away. He flung his overcoat half out of the window to cover the armorial bearings upon the panel, but I had seen them in the glare of our fanlight none the less. I gasped with surprise. Then I turned back and ascended the stair to Holmes’s room.

“I have found out who our client is,” I cried, bursting with my great news. “Why, Holmes, it is —”

“It is a loyal friend and a chivalrous gentleman,” said Holmes, holding up a restraining hand. “Let that now and forever be enough for us.”

I do not know how the incriminating book was used. Sir James may have managed it. Or it is more probable that so delicate a task was entrusted to the young lady’s father. The effect, at any rate, was all that could be desired.
