"No, nothing new, Monsieur le Préfet," replied Mazeroux.

"That's funny. The confounded fellow must be somewhere. Or can he have got away over the roof?"

"Impossible, Monsieur le Préfet," said a third voice, which Don Luis recognized as that of Weber, the deputy chief detective. "Impossible. We made certain yesterday, that unless he has wings—"

"Then what do you think, Weber?"

"I think, Monsieur le Préfet, that he is concealed in the house. This is an old house and probably contains some safe hiding-place—"

"Of course, of course," said M. Desmalions, whom Don Luis, peeping through the curtains, saw walking to and fro in front of the alcove. "You're right; and we shall catch him in his burrow. Only, is it really necessary?"

"Monsieur le Préfet!"

"Well, you know my opinion on the subject, which is also the Prime Minister's opinion. Unearthing Lupin would be a blunder which we should end by regretting. After all, he's become an honest man, you know; he's useful to us and he does no harm—"

"No harm, Monsieur le Préfet? Do you think so?" said Weber stiffly.

M. Desmalions burst out laughing.
