“Perhaps he has written to him?”

“I’ll bet you my head he has not. Having your orders to watch his correspondence, I invented a little system which informs me every time he touches a pen; during the last twenty-four hours the pens have not been touched.”

“Clameran went out yesterday.”

“But the man who followed him says he wrote nothing on the way.”

“Then we have time yet!” cried Verduret. “Hurry! Hurry! I give you fifteen minutes to make yourself a head; you know the sort; I will watch the rascal until you come up.”

The delighted Joseph disappeared in a twinkling; while Prosper and M. Verduret remained at the window observing Clameran, who, according to the movements of the crowd, was sometimes lost to sight, and sometimes just in front of the window, but was evidently determined not to quit his post until he had obtained the information he sought.

“Why do you devote yourself exclusively to the marquis?” asked Prosper.

“Because, my friend,” replied M. Verduret, “because—that is my business, and not yours.”

Joseph Dubois had been granted a quarter of an hour in which to metamorphose himself; before ten minutes had elapsed he reappeared.

The dandified coachman with Bergami whiskers, red vest, and foppish manners, was replaced by a sinister-looking individual, whose very appearance was enough to scare any rogue.
