"Yes, it is, rather," said Chet, adding seriously: "I wonder if there could really be any connection between the two."
"There's no use wondering, that I can see," said Mrs. Gilligan, preparing to send them off to their respective bedrooms. "I think the best thing we can do is not to notice them any more. Perhaps the ghosts will get tired, if they find they don't worry us," this last with a chuckle.
"Well, but they do worry us," said Violet plaintively. "Every time I hear that piano, I just about die of fright."
"Listen," commanded Billie, and as they listened they heard it again! The ghost, or whatever it was, was surely making a joke of them that night!
As soon as the boys could recover from their surprise they tumbled down the stairs, tripping over each other in their hurry, while the girls followed more slowly.
But again the noise stopped abruptly, and when they entered the room there was nothing to be seen or heard.
"Say, this thing is making me mad!" cried Ferd, glaring at the old piano as though it were the offender. "I don't mind meeting an honest-to-goodness ghost, but I'll be hanged if I'll let him laugh at me!"
"I don't see how you're going to help it," said Teddy. "Come on, fellows, it's pretty nearly morning, and we can decide then what we'll do to catch Mr. Ghost. I'm so sleepy I'm apt to fall asleep on my feet."
So they went upstairs again, feeling rather miserable and dragged out with excitement, and crawled into bed.
"If this thing keeps up much longer, I'll just be a wreck, that's all," groaned Laura, and almost immediately she fell asleep.
