“But the sentry saw you; fortunately it was too dark to distinguish your face. They are sure to search again. I think the moment has come, Monsieur de Céligny, if I am to help you further, for you to tell me a little more. You see that I am your friend, and that I am not . . . in fear of the Directory. You need not name anyone unless you wish, but I think you had better tell me for what reason you were in the park of Mirabel last night.”

“Madame,” replied Roland with emotion, “after what you have done for me I should indeed be foolish and ungrateful if I kept back anything from you. I came to Mirabel to find the hidden treasure.”

The Duchesse de Trélan stared at him. “But, my child, there is no such thing!”

From the pillow the young man’s look said as politely as possible, “How can you be sure of that, Madame la concierge?”

“I have known the château for many years,” said Valentine, “and I assure you. . . .” She broke off, puzzled.

“But I have seen a plan of its hiding-place,” said Roland eagerly.

“Where did you see such a thing?”

“When I was in Brittany with M. de——” some remnant of caution checked him, “—with a Chouan leader.”

“A Chouan leader had a plan of a treasure hidden in Mirabel!” exclaimed Mirabel’s mistress, strongest amazement in her tone. “What was his name—no, I will not ask you that. Did he send you here, then?”

“No, Madame,” admitted Roland, with a return of shamefacedness. “He will be very angry with me—if ever I see him again.” He gave a second or two to inward contemplation, presumably, of this anger, and went on, “The money was hidden here during the Fronde by the Duc of those days, but the paper describing its whereabouts was stolen, and came into the hands of an old lady who was dying in the next house to . . . to where we were. Our aumônier went to see her, and she gave him the paper to convey to the Duc de Trélan, who, I believe, is in England, or somewhere of the sort. At any rate he is an émigré—as I suppose you know, Madame.”
