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— Hôtel. 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 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 doggerel myself.’
