“That is so,” said Colonel Emsworth.

“I foresaw this situation,” I explained, “and I have brought with me a friend whose discretion may absolutely be trusted. I was able once to do him a professional service, and he is ready to advise as a friend rather than as a specialist. His name is Sir James Saunders.”

The prospect of an interview with Lord Roberts would not have excited greater wonder and pleasure in a raw subaltern than was now reflected upon the face of Mr. Kent.

“I shall indeed be proud,” he murmured.

“Then I will ask Sir James to step this way. He is at present in the carriage outside the door. Meanwhile, Colonel Emsworth, we may perhaps assemble assemble in your study, where I could give the necessary explanations.”

And here it is that I miss my Watson. By cunning questions and ejaculations of wonder he could elevate my simple art, which is but systematized common sense, into a prodigy. When I tell my own story I have no such aid. And yet I will give my process of thought even as I gave it to my small audience, which included Godfrey’s mother in the study of Colonel Emsworth.

“That process,” said I, “starts upon the supposition that when you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth. It may well be that several explanations remain, in which case one one tries test after test until one or other of them has a convincing amount of support. We will now apply this principle to the case in point. As it was first presented to me, there were three possible explanations of the seclusion or incarceration of this gentleman in an outhouse of his father’s mansion. There was the explanation that he was in hiding for a crime, or that he was mad and that they wished to avoid an asylum, or that he had some disease which caused his segregation. I could think of no other adequate solutions. These, then, had to be sifted and balanced against each other.

“The criminal solution would not bear inspection. No unsolved unsolved crime had been reported from that district. I was sure of that. If it were some crime not yet discovered, then clearly it would be to the interest of the family to get rid of the delinquent and send him abroad rather than keep him concealed at home. I could see no explanation for such a line of conduct.

“Insanity was more plausible. The presence of the second person in the outhouse suggested a keeper. The fact that he locked the door when he came out strengthened the supposition and gave the idea of constraint. On the other hand, this constraint could not be severe or the young man could not have got loose and come come down to have a look at his friend. You will remember, Mr. Dodd, that I felt round for points, asking you, for example, about the paper which Mr. Kent was reading. Had it been the Lancet or the British Medical Journal it would have helped me. It is not illegal, however, to keep a lunatic upon private premises so long as there is a qualified person in attendance and that the authorities have been duly notified. Why, then, all this desperate desire for secrecy? Once again I could not get the theory to fit the facts.

"Shall I tell you what is happening, monsieur le secretaire-general? Well, you too are having your head turned by all this this business Now that you possess the list, your state of mind has suddenly sunk to that of a Daubrecq or a d'Albufex. There is no longer even a question, in your thoughts, of taking it to your superiors, so that this ferment of disgrace and discord may be ended. No, no; a sodden temptation has seized upon you and intoxicated you; and, losing your head, you say to yourself, 'It is here, in my pocket. With its aid, I am omnipotent. It means wealth, absolute, unbounded power. Why not benefit by it? Why not let Gi1hert and Clarisse Mergy die? Why not lock up that idiot of a Lupin? Reference Why not seize this unparalleled piece of fortune by the forelock?"'

He bent toward Prasville and, very softly, in a friendly and confidential tone, said:

"Don't do that, my dear sir, don't do it."

"And why not?"

"It is not to your interest, believe me."

"Really!"

"No. Or, if you absolutely insist on doing it, have the kindness first to consult the twenty-seven names on the list of which you have just robbed me and reflect, for a moment, on the name of the third person on it."

"Oh? And what is the name of that third person?"

"It is the name of a friend of yours."

"What friend?

"Stanislas Vorenglade, the ex-deputy."

"And then?" said Prasville, who seemed to be losing some of his self-confidence.

"Then? Ask yourself if an inquiry, however summary, would not end by discovering, behind that Stanislas Vorenglade, the name of one who shared certain little profits with him."

"And whose name is?"

"Louis Prasville."

M. Nicole banged the table with his fist.

"Enough of this humbug, monsieur! For twenty minutes, you and I have been beating about the bush. That will do. Let us understand each other. And, to begin with, drop your pistols. You can't imagine that I am frightened of those playthings! Stand up, sir, stand up, as I am doing, and finish the business: I am in a hurry."

He put his hand on Prasville's shoulder and, speaking with great deliberation, said:

"If, within an hour from now, you are not back from the Elysee, bringing with you a line to say that the decree of pardon has been signed; if, within one hour and ten minutes, I, Arsene Lupin, do not walk out of this building safe and sound and absolutely free, this evening four Paris newspapers will receive four letters selected from the correspondence exchanged between Stanislas Vorenglade and yourself, the correspondence which Stanislas Vorenglade sold me this morning. Here's your hat, here's your overcoat, here's your stick. Be off. I will wait for you."

Then happened this extraordinary and yet easily understood thing, that Prasville did not raise the slightest protest nor make the least show of fight. He received the sudden, far-reaching, utter conviction of what the personality known as Arsene Lupin meant, in all its breadth and fulness. He did not so much as think of carping, of pretending - as he had until then believed - that the letters had been destroyed by Vorenglade the deputy or, at any rate, that Vorenglade would not dare to hand them over, because, in so doing, Vorenglade was also working his own destruction. No, Prasville did not speak a word He felt himsell caught in a vise of which no human strength could force the jaws asunder. There was nothing to do but yield. He yielded.
