"All the girls from Nellie's dorm, we four and Caroline Brant," Billie said, in a voice scarcely above a whisper.

"But I don't think Caroline will come," said Laura doubtfully. "You know she would lots rather study than go to a party. That's her idea of a good time."

For although Caroline Brant had proved a good friend to the chums, especially to Billie, they had tried in vain to draw her into their little escapades. She was what the girls usually referred to scornfully as "a grind," yet, strange to say, they all loved her.

She willingly helped them with their lessons, had often coached some of the more backward of them for tests, passing them when otherwise they would have hopelessly flunked, and cheerfully helped them out of scrapes when they needed help.

So now it was not strange that Laura should expect her to refuse an invitation to this new escapade—the most forbidden of all forbidden escapades, the midnight feast.

"Well, I'm going to ask her, anyway," Billie said in answer to Laura's objection. "The worst she can do is to say she won't come."

"But you're going to ask Rose, aren't you?" Connie broke in, adding, as Billie frowned and looked doubtful: "She'd never in the world forgive you if you didn't."

"Yes, we'll ask Rose," said Billie, after a minute's hesitation. "Here she comes now," she added, as the door opened and Rose entered. "Come on over here," she called, "I want to ask you something."

She was just about to tell Rose the plans and invite her to the party when the door opened again and Amanda entered with Eliza Dilks. Amanda was never seen without Eliza trailing along in the background, and for this reason the girls had nicknamed the latter, "The Shadow."

By this time the girls at Three Towers Hall had learned to dislike the two sneaks as much as the girls of North Bend disliked Amanda.
