He was whistling very quietly, "_Oh, boy, where do we go from here ?_" He had whistled that same tune more than a year before when he was waiting for a glimpse of "Dr.Curry," spy and bomb plotter, aboard the vessel on which Tom was working at that time.

He had whistled it as he escorted the "doctor" down the companionway.

How well Tom remembered! "Come on, Tommy," he said, jumping suddenly to his feet.
Tom followed.

But Mr.Conne did not speak; he was still busy with the tune.
