“Nay—that you shall know anon,” interrupted the lieutenant. “In the name of his serene highness, the duke, I command you in the first place to lead me and my followers to the presence of your master.”

The old man hastened to obey this mandate, and he conducted the sbirri into the chamber where Wagner, having thrown off his garments, was partaking of that rest which he so much needed.

“What means this insolent intrusion?” he exclaimed, his cheeks flushing with anger at the presence of the police.

“A dreadful crime!” ejaculated Wagner.

“Yes, signor; a crime——”

The officer was interrupted by an ejaculation of surprise which burst from the lips of his attendant sbirro; and, turning hastily round, he beheld his follower intently scrutinizing the attire which Fernand had ere now thrown off.
