“What you going to do with us?” queried Bill.

“Never mind; you’ll learn that soon enough. How many more are there of you?”

“There’s six in the room below and four more in the passageway,” said the leader, lying glibly. “So you’d better let us go, and take a sneak while you can. We’ll get the best of you in the end.”

“There’s only one more in your party,” said Tom, making a shrewd guess, “and I guess we’ll find a way to get him.”

“Oh, you won’t get any of the others,” said Bill. “They’re out on the river by this time. Don’t you s’pose we leave things clear for our escape when we come over here?”
