For a minute there was silence and Billie knew that Connie was staring through the dark at her in absolute amazement.

“You perfectly silly goose,” said Connie then, her bewilderment changing to indignation. “Now I know who wants to be shaken. Lie down here, Billie, and see if you can act sensibly. Sorry I asked you!” she exploded indignantly. “Why, who ever heard of such a thing!”

“But you said you wanted to solve the mystery—if there is one,” Billie reminded her, lying down again.

“Well, of course I do. So do all the rest of you,” Connie shot back. “But as to being sorry I asked you, why, I’ve a good mind——” She rose threateningly in the bed and Billie put out a pleading hand, saying with a chuckle:

“Please don’t kill me or do whatever you were going to. I take it all back.”

“I should say you’d better!” sputtered Connie, coming down with a thump in the bed.

“What are you girls raving about?” asked a sleepy voice from the next room that they recognized as Vi’s. “Can’t you keep still and let a fellow sleep? Laura’s snoring already.”

“Oh, I am not!” came indignantly from Laura. “I never snore!”

“How do you know?” asked Vi with interest.

“Know!” sputtered Laura. “Why, I don’t know how I know, but I do know.”
