"Yes, they are said to live here; two acrobats, named Girdel and Fanfaro."

"Inspector, I am inconsolable; but I will not oppose you; do your duty," said Aube, with the mien of a man who gives a kingdom away.

Arthur and the landlord exchanged knowing looks as the inspector strode toward the door. Fanfaro must be in safety by this time.

"The house is surrounded," said the inspector, as he went away, "and I think we shall have little to do."

Montferrand trembled. Suppose Fanfaro had been captured! The policemen went to the upper story, which had been pointed out to them by the landlord as the residence of Girdel and Fanfaro.

"Open, in the name of the law!" thundered a voice, which shook the house; and then followed, hardly less loud, the angry exclamation:

"By Jupiter, the nest is empty; the birds have flown!"

At this moment a voice cried from the street:

"Inspector, they are escaping over the roofs."

It was Simon, the worthy steward of the Marquis of Fougereuse, who assisted the police to-day. He had stationed himself, with several officers, in front of the house, and had noticed two shadows gliding over the roofs.
