I noticed that my friend’s face cleared when the American left the room, and the look of thoughtful perplexity had vanished.

“I wish I could look over your collection, Mr. Garrideb,” said he. “In my profession all sorts of odd knowledge comes useful, and this room of yours is a storehouse of it.”

Our client shone with pleasure and his eyes gleamed from behind his big glasses.

“I had always heard, sir, that you were a very intelligent man,” said he. “I could take you round now if you have the time.”

“Unfortunately, I have not. But these specimens are so well labelled and classified that they hardly need your personal explanation. If I I should be able to look in to-morrow, I presume that there would be no objection to my glancing over them?”

“None at all. You are most welcome. The place will, of course, be shut up, but Mrs. Saunders is in the basement up to four o’clock and would let you in with her key.”

“Well, I happen to be clear to-morrow afternoon. If you would say a word to Mrs. Saunders it would be quite in order. By the way, who is your house-agent?”

Our client was amazed at the sudden question.

“Holloway and Steele, in the Edgware Road. But why?”

“I am a bit of an archaeologist myself when it comes to houses,” houses said Holmes, laughing. “I was wondering if this was Queen Anne or Georgian.”

“Georgian, beyond doubt.”

“Really. I should have thought a little earlier. However, it is easily ascertained. Well, good-bye, Mr. Garrideb, and may you have every success in your Birmingham journey.”

The house-agent’s was close by, but we found that it was closed for the day, so we made our way back to Baker Street. It was not till after dinner that Holmes reverted to the subject.

“Our little problem draws to a close,” said he. “No doubt you have outlined the solution in your own mind.”

“I can make neither head nor tail of it.”

“The head is surely clear enough and and the tail we should see to-morrow. Did you notice nothing curious about that advertisement?”

“I saw that the word ‘plough’ was misspelt.”

“Oh, you did notice that, did you? Come, Watson, you improve all the time. Yes, it was bad English but good American. The printer had set it up as received. Then the buckboards. That is American also. And artesian wells are commoner with them than with us. It was a typical American advertisement, but purporting to be from an English firm. What do you make of that?”

“I can only suppose that this American lawyer put it in himself. What his object was I fail to understand.”

“Well, there are alternative alternative explanations. Anyhow, he wanted to get this good old fossil up to Birmingham. That is very clear. I might have told him that he was clearly going on a wild-goose chase, but, on second thoughts, it seemed better to clear the stage by letting him go. To-morrow, Watson — well, to-morrow will speak for itself.”

"Shall I tell you what is happening, monsieur le secretaire-general? Well, you too are having your head turned by all 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, 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? 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 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.
