“Yes; but that is when the princess within secretly favours his efforts,” said Isabelle, with a mischievous smile, “and in some mysterious way constitutes herself his accomplice; being tired of her seclusion, perhaps, or else in love with the bold intruder—neither of which is my case you know, de Sigognac!
