“O 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 honor 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 rigorously searched under my own inspection.”

“You might have spared yourself this trouble,” said Dupin.  “D—­, I presume, is not altogether a fool, and, if not, must have anticipated these waylayings, as a matter of course.”

“Not altogether a fool,” said G., “but then he’s a poet, which I take to be only one remove from a fool.”

“True,” said Dupin, after a long and thoughtful whiff from

his meerschaum, “although I have been guilty of certain doggrel myself.”

“Suppose you detail,” said I, “the particulars of your search.”

“Why the fact is, we took our time, and we searched every where.  I have had long experience in these affairs.  I took the entire building, room by room; devoting the nights of a whole week to each.  We examined, first, the furniture of each apartment.  We opened every possible drawer; and I presume you know that, to a properly trained police agent, such a thing as a secret drawer is impossible.  Any man is a dolt who permits a ‘secret’ drawer to escape him in a search of this kind.  The thing is so plain.  There is a certain amount of bulk — of space — to be accounted for in every cabinet.  Then we have accurate rules.  The fiftieth part of a line could not escape us.  After the cabinets we took the chairs.  The cushions we probed with the fine long needles you have seen me employ.  From the tables we removed the tops.”
