"What is it you wanted to say, Billie?" asked Caroline in her matter-of-fact tone. "If it's anything very private, I guess we'd better move."

Caroline had been thinking about Rose and the happening of the night before—thinking till her head ached—but she had not yet decided what to do about it. As for Rose—her head ached, too—she knew what she was going to do about it. Some way or other she was going to get even with Billie! And Caroline, too, big snooping, spectacled thing!

"It isn't a bit private," said Billie, looking so serious that the girls suddenly became serious too. "It was about something I saw last night after——" she was about to say "after the party," but as Amanda and her "Shadow" had come dangerously near and were listening with all their ears, she decided not to.

"Well, what was it you saw?" the girls demanded impatiently, as she hesitated.

Billie lowered her voice and spoke hurriedly.

"I saw him going across the lawn. He was running, and while I watched he disappeared among the trees near the lake."

"A man?" asked Vi while the others stared.

"Of course," Billie nodded impatiently. "What did you think it was—a grizzly bear?"

"It might have bees from your description," Vi retorted, but right here the girls broke in with a running fire of questions and Billie was kept busy trying to answer them all at once.

"But, Billie, why didn't you tell somebody?" Vi asked, but Laura crushed her with a look.
