“Nonsense!” cried Cora. “It will make it all the more interesting. Think of the fun we can have, organizing ghost-detecting parties, sitting up until all hours of the night, daring the boys to sit with us. And then, after all, finding out it is only the tricks of some alleged fun-loving person, or perhaps boys of the neighborhood.”

“Do you really think so, Cora?” Belle asked.

“Why, yes.”

“I don’t know,” murmured Bess, thoughtfully.

“Come! Where has all the bravery of the Motor Girls vanished to?” demanded Cora with a silvery laugh. “We didn’t act thus timidly when we solved the secret of the red oar on Crystal Bay. And perhaps——”

“Cora’s right!” interrupted Belle.

“She generally is,” contributed Bess.

“There’s a secret here, and we will solve it!” her sister went on. “I didn’t look at it that way before, but I see it now. We mustn’t be driven away, or kept from going just because of these rumors. We’ll go to Camp Surprise and surprise those who are making such a fuss there. I wonder some one hasn’t done it long ago.”

“Just what I was about to remark,” came from Cora. “I’m glad to see that your natural courage has come back. I thought it would. We haven’t been together on various quests for nothing. Now we’ll prove ourselves true Motor Girls, and get at the bottom of these surprising happenings. You won’t back out?”

“Never!” affirmed Bess.
