“Smart, aren’t you?” sneered the German. He raised his hand suddenly and, before Frank could realize his intention, slapped the lad smartly across the face.

Frank took a step forward and his hands clenched. His face turned red and he was about to return the blow. A second time his better judgment prevailed and he stepped back, remarking quietly:

“You shall answer for that, Lieutenant Holzen!”

“What! you know my name?” exclaimed the German. “So I shall answer, eh? Yes, so I shall, at any time and place that suits your convenience.”

“I am no duelist,” said Frank quietly.

“No; you are a coward,” was the retort.

Again Frank’s face turned red and his hands clenched; but he restrained himself.

“For that you shall answer also,” he said. “Now, stand aside. I would pass.”

“Not much!” said Lieutenant Holzen. “First you must tell me the time and place of meeting.”

“Look here, I’m getting tired of this foolishness,” said Frank. “Get out of my way.”
