Penny and Louise promptly assured her that they would tell no one about the pearls.
“Another thing—” Mrs. Marborough hesitated and then went on. “I suppose you understand now why I never invited you into the house. It wasn’t that I meant to be inhospitable.”
“Because the place isn’t fixed up?” Louise came to her aid. “Why, Penny and I would have thought nothing of it. This is a cozy kitchen with a cheerful fire. I think it’s nice.”
“I probably shan’t be here long. My purpose in returning to Riverview was to find the pearls. I’ve nearly made up my mind that they are lost forever.”
“Oh, don’t say that!” Penny cried. “Tomorrow, with your permission, Louise and I will explore the tunnel. We may have luck.”
“I shall be very glad to have your help, my dear.” Again Mrs. Marborough groped for words and finished awkwardly: “Please, I beg of you, don’t tell anyone what you have seen tonight, particularly the barren state of this house.”
“We understand,” Penny said gravely.
The fire had burned low. Mindful that they must be home early, the girls bade Mrs. Marborough goodbye, promising to return the following day. Once outside the mansion, they paused beside a tree so that Penny might remove the heavy coveralls which she still wore over her frock.
“What a night!” she murmured happily.
“For once, Penny, one of your crazy adventures turned out beautifully,” Louise praised. “We’ll have a wonderful time searching for that necklace! She’s certainly queer though.”
