"They're puzzled, chief"—Sage knocked the ashes from his pipe into the ash-tray on the table—"and they're getting jumpy," he added.

Colonel Walton nodded.

"Twice they've ransacked John Dene's room at the Ritzton and found nothing."

"Does he know?" enquired Colonel Walton.

Sage nodded.

"John Dene's a dark horse," he remarked with respect in his voice, "and the Huns can't make up their minds."

"To what?" enquired the chief.

"To give up the shadow for the substance," he remarked, as he pressed down the tobacco in his pipe. "They want the plans, and they want to prevent the boat from putting to sea."

Colonel Walton nodded comprehendingly.

"They'll probably try to scotch her on the way over; but they won't know her route. They'll be lying in wait, however, in full strength in home waters. He's a bad psychologist," added Sage, as he knocked the ashes out of his pipe.
