Ferd and Teddy spoke almost in the same breath.

"No, I want you all to go up and get into bed," said Mrs. Gilligan decidedly. "If I see anything," she added, with a grim smile, "anything that looks like a ghost that is, I'll call you."

"That's a promise," said Chet, looking back over his shoulder as he reluctantly followed the others upstairs. "Because if I should miss getting a look at that ghost, I'd be disappointed for life."

"Well, I've had enough of spooks to last me forever," said Laura, with a shivery glance over her shoulder as the boys left the girls at their door and started off down the hall. "If that piano begins to play itself again to-night, I'll just die, that's all there is to it."

The girls crept into bed, careful to leave their candles burning.

"You know, Billie," said Violet in an awed little voice, "this thing is really getting serious."

"I should say so," agreed Laura, drawing the bed clothes a little tighter about her.

"Well, it isn't my fault, is it?" asked Billie. "I didn't ask Aunt Beatrice to leave me a haunted house. And, anyway," she added very truthfully, "it was you, Laura, who first suggested coming here."

"Yes," went on Violet accusingly, "and it was you who said you'd be disappointed if you didn't see a ghost or two."

Laura groaned.
