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 spunging 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.

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 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 explanations.

"The Parisian police," he said, "are exceedingly a
