"We hunted inside and outside of that hut," insisted the Judge. "If he had been there, surely there would have been some sign."

"I have an idea!" cried Bet, jumping to her feet. "I believe he's in that hut, they put him back after you'd been there. I'm going to find him tonight."

"You'll do no such thing, Bet. Chasing around among a lot of bad men is no place for a girl," began her father, but Bet interrupted:

"Just wait until I have worked out my plan and you'll see I'll be as safe as if I were at home. You can come with me, Dad. Will you help me, Judge? I'll need several men."

"Let us in on this," exclaimed Phil and Bob in the same breath. "We'd like to have a hand in solving your latest mystery."

Bet flew to her room and returned in a few minutes in a strange costume, a long dress of buckskin. Dark braids fell over her shoulders and feathers rose from her hair. She had no resemblance to the boyish girl they knew.

The Colonel looked puzzled but Judge Breckenridge caught the idea. "You're a wonder, Bet! And I do believe you are right. You'll be as safe as if you were in your own bed."

An hour later, the watchers by the hut rubbed their eyes and stared about them. A wild, weird cry rang through the canyon, and in the moonlight Kie Wicks and his bad men saw, far above them on the cliff, the figure of an Indian girl.

"She wasn't walking, she was just floating in the air, it seemed, and as she moved, she moaned and shrieked. It was terrible! There was no doubt about it. It was the ghost," Kie Wicks told his wife when he was safely at home.

"What happened?" Maude urged him to continue the story.
