"How much did Merle find out in the lantern room?" interposed Lindsay.
"She happened to pull at the lantern, and had just the same surprise as you," replied Monica. "She had gone a few steps into the passage when I came down from looking at the cistern, and met her, much to her astonishment. Of course I explained everything, and begged her not to tell, because we didn't want any more schoolgirls to start exploring."
"Then it was to you she gave that mysterious promise?"
"Certainly it was to me. I'm glad to hear she kept it so well."
"But I still don't half understand," said Lindsay. "We thought Mrs. Wilson and Scott were hiding the treasure up there. We saw them take a sack into the garden one night and bury something."
"You managed to give poor Scott a great fright," laughed Monica. "He told me about it the next day. He was doing nothing more dreadful than digging out a wasps' nest. Mrs. Wilson had discovered it in the bank, and she went with him to show him the place and help him. Of course it could not be done by daylight, when the wasps were flying about; but at dark, when they were all safely inside their hole, Scott burnt tobacco to stupefy them, and then took the nest. He said two of the young ladies had suddenly tumbled down the bank while he was at work, and startled him terribly."
"So he and Mrs. Wilson weren't burying the treasure after all? They didn't even try to steal it?"
"No, indeed! I feel sorry to think they should have been suspected for a moment of such bad intentions. Mrs. Wilson may be rather gruff and blunt in her manners, but she is a faithful old soul, and devoted to Mother and me. I believe she would have starved rather than touch a penny that belonged to us. And Scott too is absolutely honest. I assure you he keeps nothing stowed away inside the cucumber frames! Naturally Mrs. Wilson had often looked for the hiding-place, but it was all on my behalf, and nobody rejoiced more heartily than she did when it was found."
"We were on a completely wrong track," said Lindsay. "The only right clue was the enigma. I'm glad we puzzled that out, though we didn't win any prizes in the competition."
"And yet the enigma was no real use," put in Cicely. "We shouldn't have gone through the bottom of the settle if we hadn't been playing hide-and-seek. Isn't it queer that when we tried so hard to find the secret room we couldn't, and then that we should come across it just by accident?"
