The lad's eyes had now become more accustomed to the light. He could see that his visitor was a broad-shouldered, muscular man of average height, florid-featured, and with light-yellow hair and a fair moustache. He was dressed in a uniform that was apparently a bad copy of that worn by executive officers of the British Navy. On the breast of his coat he wore an Iron Cross.
"Me Hermann Rix, Ober-leutnant of unterseeboot," he announced. "Der Kapitan send me to see how you get better. Goot! I tell seaman to bring food quick. In one hour you go on deck. Den you feel all well."
The German Leutnant bent and peered into the lower cot.
"Fat head," he remarked seriously. "Bad knock, but he get well soon."
With that the officer went away, leaving the light switched on.
Scrambling out of his bunk, Ross approached his chum. Vernon was now sleeping quietly. His face, however, was flushed, while it was quite evident that he had received a fairly heavy blow across the skull, for the top of his head was swollen to a considerable extent.
Before Ross had finished his examination a sailor entered, bearing a tray on which were three slices of rye bread, some tinned beef, and a bottle of Rhenish wine.
"Sprechen Sie deutsch?" he asked.
For an instant Trefusis hesitated before replying. To profess ignorance of the German language would be an immense advantage while on board the submarine, provided he could control his facial expressions and listen without betraying himself. Then, on the other hand, he reflected that Ramblethorne, the spy, might have been instrumental in getting him into this predicament. More than likely the Captain of the submarine had been informed of the fact that his unconscious passengers were well acquainted with the tongue-twisting language of the Fatherland.
"Here is food for you," said the man, placing the tray on the floor. "You had better take hold of the bottle before it upsets. We are rolling a bit. When your friend open his eyes, call me. I am in yonder compartment. It would be well for you to dress. I will bring your clothes to you very soon."
Ross made a sorry meal. The food was not at all appetizing. His throat was in no condition to enable him to swallow easily. A feeling of nausea, due either to the motion, the hot, confined air, or the after effects of the stupefying injection—perhaps a little of all three—was still present.
He was actually on board a German submarine—one of Tirpitz's twentieth-century pirates. He racked his brains to find a reason. With its limited accommodation an unterseeboot seemed the last type of craft that would receive a pair of prisoners—and non-combatants—within its steel-clad hull. It must have been at Ramblethorne's instigation; yet why had not the spy knocked the pair of luckless eavesdroppers over the head and tumbled them into the sea? It seemed by far the easiest solution; yet, in spite of that, Ross and Vernon were being carried to an unknown destination in one of the "mystery-craft" of the Imperial German Navy.
The reappearance of the seaman bearing Ross's clothes cut short the latter's unsolved meditations. Without a word the man laid the neatly folded garments on the bunk—a pair of flannel trousers, cricket shirt, underclothes, and the sweater that had been the cause of the lads' undoing; but in place of his shoes a pair of half-boots, reeking with tallow, had been provided.
Ross proceeded to dress. As he did so a voice that he hardly recognized asked:
"Hulloa, Trefusis, where are we?"
It was Haye. His companion was now awake, but hardly conscious of his surroundings.
"Better?" asked Ross laconically. He could not at that moment bring himself to answer the question.
"Didn't know that I was ill," remonstrated Vernon. Then, after a vain attempt to raise his head—perhaps fortunately, since the bottom of Ross's cot was within a few inches of his face—he added:
"Dash it all! I remember. That beastly German gave me a crack over the head with his copper walking-stick. Where are we?"
"In a rotten hole, old man. We're in a German submarine, bound goodness knows where."
"Where are my clothes?" asked Haye, this time successfully getting out of his bunk. "Since you have yours, there seems to be no reason why I shouldn't have mine. Hang it! What's the matter with me? Everything's spinning round like a top."
