no; nothing of that nature. The fact is, the business is very simple indeed, and I make no doubt that we can manage it sufficiently well ourselves; but then I thought Dupin would like to hear the details of it, because it is so excessively odd."
"Simple and odd?" said Dupin.
"Why, yes; and not exactly that either. The fact is, we have all been a good deal puzzled because the affair is so simple, and yet baffles us altogether."
"Perhaps it is the very simplicity of the thing which puts you at fault," said my friend.
"What nonsense you do talk!" replied the Prefect, laughing heartily.
"Perhaps the mystery is a little too plain," said Dupin.
"Oh, good heavens! who ever heard of such an idea?"
"A little too self-evident."
"Ha! ha! ha!—ha! ha! ha!—ho! ho! ho!" roared our visitor, profoundly amused. "Oh, Dupin, you will be the death of me yet!"
"And what, after all, is the matter on hand?" I asked.
"Why, I will tell you," replied the Prefect, as he gave a long, steady, and contemplative puff and settled himself in his chair,—"I will tell you in a few words; but, before I begin, let me caution you that this is an affair demanding the greatest secrecy, and that I should most probably lose the position I now hold were it known that I confided it to anyone."
"Proceed," said I.
"Or not," said Dupin.
"Well, then; I have received personal information, from a very high quarter, that a certain document of the last importance has been purloined from the royal apartments. The individual who purloined it is known—this beyond a doubt; he was seen to take it. It is known, also, that it still remains in his possession."
"How is this known?" asked Dupin.
"It is clearly inferred," replied the Prefect, "from the nature of the document and from the non-appearance of certain results which would at once arise from its passing out of the robber's possession, that is to say, from his employing it as he must design in the end to employ it."
"Be a little more explicit," I said.
"Well, I may venture so far as to say that the paper gives its holder a certain power in a certain quarter where such power is immensely valuable." The Prefect was fond of the cant of diplomacy.
"Still I do not quite understand," said Dupin.
"No? Well; the disclosure of the document to a third person, who shall be nameless, would bring in question the honour of a personage of most exalted station; and this fact gives the holder of the document an ascendency over the illustrious personage whose honour and peace are so jeopardized."
"But this ascendency," I interposed, "would depend upon the robber's knowledge of the loser's knowledge of the robber. Who would dare—"
"The thief," said G——, "is the Minister D——, who dares all things, those unbecoming as well as those becoming a man. The method of the theft was not less ingenious than bold. The document in question,—a letter, to be frank,—had been received by the personage robbed while alone in the royal boudoir. During its perusal she was suddenly interrupted by the entrance of the other exalted personage from whom especially it was her wish to conceal it. After a hurried and vain endeavour to thrust it in a drawer, she was forced to place it, open as it was, upon a table. The address, however, was uppermost, and, the contents thus unexposed, the letter escaped notice. At this juncture enters the Minister D——. His lynx eye immediately perceives the paper, recognizes the handwriting of the address, observes the confusion of the personage addressed, and fathoms her secret. After some business transactions, hurried through in his ordinary manner, he produces a letter somewhat similar to the one in question, opens it, pretends to read it, and then places it in close juxtaposition to the other. Again he converses for some fifteen minutes upon the public affairs. At length, in taking leave, he takes also from the table the letter to which he had no claim. Its rightful owner saw, but, of course, dared not call attention to the act, in the presence of the third personage, who stood at her elbow. The Minister decamped, leaving his own letter, one of no importance, upon the table."
"Here, then," said Dupin to me, "you have precisely what you demand to make the ascendency complete, the robber's knowledge of the loser's knowledge of the robber."
"Yes," replied the Prefect; "and the power thus attained has, for some months past, been wielded, for political purposes, to a very dangerous extent. The personage robbed is more thoroughly convinced every day of the necessity of reclaiming her letter. But this, of course, cannot be done openly. In fine, driven to despair, she has committed the matter to me."
"Than whom," said Dupin, amid a perfect whirlwind of smoke, "no more sagacious agent could, I suppose, be desired or even imagined."
"You flatter me," replied the Prefect; "but it is possible that some such opinion may have been entertained."
"It is clear," said I, "as you observe, that the letter is still in the possession of the Minister; since it is this possession, and not any employment of the letter, which bestows the power. With the employment the power departs."
"True," said G——; "and upon this conviction I proceeded. My first care was to make thorough search of the Minister's hotel; and here my chief embarrassment lay in the necessity of searching without his knowledge. Beyond all things, I have been warned of the danger which would result from giving him reason to suspect our design."
"But," said I, "you are quite au fait in these investigations. The Parisian police have done this thing often before."
"Oh, yes; and for this reason I did not despair. The habits of the Minister gave me, too, a great advantage. He is frequently absent from home all night. His servants are by no means numerous. They sleep at a distance from their master's apartment, and, being chiefly Neapolitans, are readily made drunk. I have keys, as you know, with which I can open any chamber or cabinet in Paris. For three months a night has not passed, during the greater part of which I have not been engaged, personally, in ransacking the D—— Hotel. My honour is interested, and, to mention a great secret, the reward is enormous. So I did not abandon the search until I had become fully satisfied that the thief is a more astute man than myself. I fancy that I have investigated every nook and corner of the premises in which it is possible that the paper can be concealed."
"But is it not possible," I suggested, "that although the letter may be in possession of the Minister, as it unquestionably is, he may have concealed it elsewhere than upon his own premises?"
"This is barely possible," said Dupin. "The present peculiar condition of affairs at court, and especially of those intrigues in which D—— is known to be involved, would render the instant availability of the document, its susceptibility of being produced at a moment's notice, a point of nearly equal importance with its possession."
"Its susceptibility of being produced?" said I.
"That is to say, of being destroyed," said Dupin.
"True," I observed; "the paper is clearly, then, upon the premises. As for its being upon the person of the minister, we may consider that as out of the question."
"Entirely," said the Prefect. "He has been twice waylaid, as if by footpads, and his person rigidly searched under my own inspection."
"You
