But they could not find anyone in the rooms.
"Maybe you just imagined it, Joy," said brother.
"No, I don't think she did. I heard a noise a little while ago when I put the fan away. I thought at the time it was Smiley Jim."
"When was that?" asked Bet.
"About fifteen minutes ago, I left the fan on top of your father's desk, Bet."
"All right, Phil. But I'd certainly like to know who is prowling around."
"It's probably one of the boys from the village who didn't get an invitation. They do that sometimes," suggested Phil. "They are probably trying to break up the party, and we're letting them do it."'
"That's right!" exclaimed the young people. "Aren't we silly! Let's get back to the games."
The scare was soon forgotten as the boys and girls became engrossed in their play and Smiley was brought in to do tricks.
But after the last guest had gone and Bet and her three chums, who were to spend the night with her, were tucked into bed. Bet thought she heard noise in her father's room.
