"Poole is knocked out clean!"

"You—you——" he began.

"Stay where you are, Nat Poole," said Dave, in a voice that was as cold as ice. "Don't you dare to budge!"

"Wha-what?"

"Don't you dare to budge until you have begged my pardon."

"Me? Beg your pardon! I'd like to see myself!"

"Well, that is just what you are going to do! If you don't, do you know what I'll do? I'll throw you into the river and keep you there until you do as I say."

"Here, you let him alone!" blustered Plum, starting to rise.
