"Not exactly, Monsieur l'Inspecteur."

"Now, Monsieur Jean," put in Mlle. Fouchette, "if Monsieur l'Inspecteur has no further questions to ask——"

"Not so fast, mademoiselle," sharply interrupted the officer. "Just wait a bit; for, while I do not claim that roof-walking at midnight is unpardonable in cats and lovers, it is especially forbidden to enter other people's houses when they are asleep."

Mlle. Fouchette's nervousness did not escape the little fishy eyes. While it was already evident that Monsieur l'Inspecteur was talking at random, it was morally certain that he would smoke them out.

"And two persons armed with a dark-lantern, coming out of a house not their own, at this time of night," continued the inspector, "are under legitimate suspicion until they can explain."

Mlle. Fouchette made a sign to Jean that he was to hold his tongue.

"Now, none of that, mademoiselle!" cried the inspector, angrily.

He rudely separated the couple, and, taking charge of the girl himself, turned Jean over to four of his agents who were near at hand.

"We'll put you where you'll have time to reflect," he said.

Mlle. Fouchette was inspired. She saw that it was not a souricière. If the inspector knew what was above, he would not have left the entrances and exits unguarded. To be absolutely sure of this, she waited until they had passed the Rue St. Jacques.
