"Where did the girl come in?"

"She came in with her uncle, of course. Ben Ali said his niece was good on the flying bar, and he brought her to see me. When she came she was in one of her spells, and looked and acted like a puppet, with some one pulling the wires. I wasn't much impressed with her, but gave her a try-out. She recovered from the spell and acted just as she did to-day, when she went up with the Comet—perfectly natural. She gave a good performance—mighty good—and I made a deal with her uncle. That's the way I got tangled up with the pair. Why?"

The showman transfixed Matt with a curious glance.

"Oh, nothing," said Matt carelessly. "The Hindoo and the girl have always been something of a mystery to me, and I wanted to find out what you knew about them. Where did they come from?"

"Give it up. I never look into the past of people who hire out to me. If they're capable, and do their work, that's enough. From what McGlory said, and from what I've seen, Ben Ali appears to have been sneaking around here, listening to what you and your friends were saying. If he hadn't inadvertently touched the keyboard of the calliope we shouldn't have known he was under the cover. Have you any notion what he means by that sort of work?"

"No."

"Well, it's deuced queer, and that's all I can say. Do you think he ought to be bounced?"

"Yes, but I wouldn't do it."

"On Haidee's account?"

"Partly that; partly, too, because, if you keep him on the pay roll, we may be able to learn something about him and the girl. I'm a bit curious about them, Burton."
