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 any one who would aid me in the matter."

"In that case," replied Dupin, opening a drawer, and producing a
check-book, "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 thunder-stricken.
For some minutes he remained speechless and motionless, looking
incredulously at my friend with open mouth, and eyes that seemed

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 pocket-book; 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 explanation.

"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 Hotel
D----, I felt entire confidence in his having made a satisfactory
investigation--so far as his labors extended."

"So far as his labors extended?" said I.

"Yes," said Dupin. "The measures adopted were not only the best of
their kind, but carried out to absolute perfection. Had the letter
been deposited within the range of their search, these fellows would,
beyond a question, have found it."

I merely laughed--but he seemed quite serious in all that he said.

"The measures, then," he continued, "were good
