Then, as the vessel regained an even keel, silently and smoothly the door slid back in its grooves, revealing a small space barely six feet in length and five in breadth, and separated from the rest of the vessel by a closed water-tight panel. Part of the compartment was occupied by a bend, at which the seaman to whom he had previously spoken was busily engaged in mending a rent in an oilskin coat.

"My friend is now awake," announced Ross.

The man laid aside his work.

"Good!" he replied. "He is just in time. I will bring him his food and his clothes. After that you will both go on deck for fresh air before you are interviewed by Herr Kapitan Schwalbe. See that door? Beyond that you must not pass without permission. It is forbidden. If you do so, you will not have another opportunity in a hurry."

"What are they going to do with us?" asked Ross.

The sailor shook his head.

"It is forbidden to ask questions," he said sternly. "Whatever is necessary that you should know will be told you."

He turned his back upon his questioner, signifying in a plain manner that it was useless for Trefusis to say more. Taking the hint the lad returned to his chum, wondering deeply at the fate that had thrown them into the hands of the enemy.
