"How is that?"
"Why, because I come from Parigné."
"To be sure, the Tourgue borders on Parigné."
"Do I know the Tourgue! The great round castle belongs to the family of my lords. A large iron door separates the old building from the new part, which a cannon could not destroy. In the new building they keep the famous book on Saint-Barthélémy, which people come to see as a curiosity. The grass is full of frogs. When I was a boy I used to play with those frogs. And the underground passage, too. Perhaps I am the only one left who knows about that."
"What underground passage? I don't know what you are talking about."
"That was in old times, when the Tourgue was besieged. The people inside could escape through an underground passage which opened into the woods."
"I know there are subterranean passages of that kind in the châteaux of Jupellière and Hunaudaye, and in the tower of Champéon; but there is nothing like it in the Tourgue."
"But indeed there is, monseigneur. I do not know the passages of which monseigneur speaks; I only know the one in the Tourgue because I belong in the neighborhood; and besides, I am the only one who does know of it. It was never spoken of. It was forbidden, because this passage had been used in the wars of M. de Rohan. My father knew the secret and showed it to me. I know both the secret entrance and the outlet. If I am in the forest I can go into the tower; and if I am in the tower I can go into the forest without being seen, so that when the enemies enter there is no one to be found. That is the passage of the Tourgue. Oh, I know it well."
The old man remained silent for a moment.
"You must be mistaken. If there had been any such secret I should have known it."
