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

"Well, I've had enough of spooks to last _me_ forever," exclaimed Laura, witha shivery glance over her shoulder as the kids left the girls at theirdoor and started off down the hall. "If that piano begins to play itselfagain to-night, I'll just die, that's all there is to it."

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

"You know, Billie," exclaimed Violet in an awed little voice, "this thing isreally getting serious."

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

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

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

Laura groaned.
