wadding of cotton be placed around it. Besides, in our case, we were obliged to proceed without noise."
"But you could not have removed, you could not have taken to pieces all articles of furniture in which it would have been possible to make a deposit in the manner you mention. A letter may be compressed into a thin spiral roll, not differing much in shape or bulk from a large knitting-needle, and in this form it might be inserted into the rung of a chair, for example. You did not take to pieces all the chairs?"
"Certainly not, but we did better: we examined the rungs of every chair in the hotel, and, indeed, the jointings of every description of furniture, by the aid of a most powerful microscope. Had there been any traces of recent disturbance we should not have failed to detect it instantly. A single grain of gimlet-dust, for example, would have been as obvious as an apple. Any disorder in the gluing, any unusual gaping in the joints, would have sufficed to insure detection."
"I presume you looked to the mirrors, between the boards and the plates, and you probed the beds and the bedclothes, as well as the curtains and carpets."
"That of course; and when we had absolutely completed every particle of the furniture in this way, then we examined the house itself. We divided its entire surface into compartments, which we numbered, so that none might be missed; then we scrutinized each individual square inch throughout the premises, including the two houses immediately adjoining, with the microscope, as before."
"The two houses adjoining!" I exclaimed; "you must have had a great deal of trouble."
"We had; but the reward offered is prodigious."
"You include the grounds about the houses?"
"All the grounds are paved with brick. They gave us comparatively little trouble. We examined the moss between the bricks and found it undisturbed."
"You looked among D——'s papers, of course, and into the books of the library?"
"Certainly; we opened every package and parcel; we not only opened every book, but we turned over every leaf in each volume, not contenting ourselves with a mere shake, according to the fashion of some of our police officers. We also measured the thickness of every book-cover with the most accurate measurement, and applied to each the most jealous scrutiny of the microscope. Had any of the bindings been recently meddled with, it would have been utterly impossible that the fact should have escaped observation. Some five or six volumes, just from the hands of the binder, we carefully probed, longitudinally, with the needles."
"You explored the floors beneath the carpets?"
"Beyond doubt. We removed every carpet and examined the boards with the microscope."
"And the paper on the walls?"
"Yes."
"You looked into the cellars?"
"We did."
"Then," I said, "you have been making a miscalculation, and the letter is not upon the premises, as you suppose."
"I fear you are right there," said the Prefect. "And now, Dupin, what would you advise me to do?"
"To make a thorough research of the premises."
"That is absolutely needless," replied G——. "I am not more sure that I breathe than I am that the letter is not at the hotel."
"I have no better advice to give you," said Dupin. "You have, of course, an accurate description of the letter?"
"Oh, yes!" and here the Prefect, producing a memorandum-book, proceeded to read aloud a minute account of the internal, and especially of the external, appearance of the missing document. Soon after finishing the perusal of this description he took his departure, more entirely depressed in spirits than I had ever known the good gentleman before.
In about a month afterward he paid us another visit, and found us occupied very nearly as before. He took a pipe and a chair and entered into some ordinary conversation. At length I said:
"Well, but, G——, what of the purloined letter? I presume you have at last made up your mind that there is no such thing as overreaching the Minister?"
"Confound him! say I—yes; I made the re-examination, however, as Dupin suggested, but it was all labour lost, as I knew it would be."
"How much was the reward offered, did you say?" asked Dupin.
"Why, a very great deal, a very liberal reward; I don't like to say how much, precisely; but one thing I will say—that I wouldn't mind giving my individual check for fifty thousand francs to anyone who could obtain me that letter. The fact is, it is becoming of more and more importance every day; and the reward has been lately doubled. If it were trebled, however, I could do no more than I have done."
"Why, yes," said Dupin, drawlingly, between the whiffs of his meerschaum, "I really—think, G——, you have not exerted yourself—to the utmost in this matter. You might—do a little more, I think, eh?"
"How? in what way?"
"Why—puff, puff—you might—puff, puff—employ counsel in the matter, eh?—puff, puff, puff. Do you remember the story they tell of Abernethy?"
"No; hang Abernethy!"
"To be sure! hang him and welcome. But, once upon a time, a certain rich miser conceived the design of sponging upon this Abernethy for a medical opinion. Getting up, for this purpose, an ordinary conversation in a private company, he insinuated his case to the physician as that of an imaginary individual.
"'We will suppose,' said the miser, 'that his symptoms are such and such; now, Doctor, what would you have directed him to take?'
"'Take!' said Abernethy, 'why, take advice, to be sure.'"
"But," said the Prefect, a little discomposed, "I am perfectly willing to take advice and to pay for it. I would really give fifty thousand francs to anyone who would aid me in the matter."
"In that case," replied Dupin, opening a drawer and producing a checkbook, "you may as well fill me up a check for the amount mentioned. When you have signed it I will hand you the letter."
I was astounded. The Prefect appeared absolutely thunderstricken. For some minutes he remained speechless and motionless, looking incredulously at my friend with open mouth, and eyes that seemed starting from their sockets; then, apparently recovering himself in some measure, he seized a pen, and after several pauses and vacant stares finally filled up and signed a check for fifty thousand francs and handed it across the table to Dupin. The latter examined it carefully and deposited it in his pocketbook; then, unlocking an escritoire, took thence a letter and gave it to the Prefect. This functionary grasped it in a perfect agony of joy, opened it with a trembling hand, cast a rapid glance at its contents, and then, scrambling and struggling to the door, rushed at length unceremoniously from the room and from the house without having uttered a syllable since Dupin had requested him to fill up the check.
When he had gone, my friend entered into some explanations.
"The Parisian police," he said, "are exceedingly able in their way. They are persevering, ingenious, cunning, and thoroughly versed in the knowledge which their duties seem chiefly to demand. Thus, when G—— detailed to us his mode of searching the premises at the
