"Quite so," assented Count Otto von Brockdorff-Giespert. "I may tell you, prisoner, that the information you refuse to give is already at our disposal. How remains our affair? I can tell you this with absolute certainty: either you will remain a prisoner of war until the end of hostilities, or you will not leave this U-boat alive. Rescue is entirely out of the question. Hence it does not matter whether I tell you a British naval secret. Those tramp steamers you were escorting were decoys. It was the intention of the British Admiral to sacrifice those ships in the hope that our torpedo-boat flotilla at Zeebrugge would be lured out to bite a tempting bait. While our boats were engaged thus, your destroyers were to attempt a raid upon our new naval base, which, like Antwerp in the time of Napoleon, is a pistol aimed at the heart of England. Unfortunately for you, the plan miscarried. Instead of our torpedo flotilla appearing, some of our unterseebooten were lying at the rendezvous, and, as a result, you are here."
He paused to watch the effect of his words. Not a muscle of the Sub's face moved. Outwardly his face was an imperturbable mask, although he was suffering the torments of acute thirst.
"And, since you are, like many others of our enemies, very curious to know what is developing at Zeebrugge," continued the Count, "it will afford me great pleasure there to offer you hospitality—of a kind. I mean to provide you with quarters and rations in a comfortable post on the Mole of Zeebrugge. If your pestering compatriots come flying over and drop bombs, and you happen to fall a victim, the responsibility is theirs, not mine. If, again, you are anxious to exchange your quarters for others beyond the Rhine, you have but to answer a few questions and the transfer will take effect."
Then, finding that Seton was apparently quite indifferent to this proposal, von Brockdorff-Giespert lost all control of his temper.
For fully two minutes he raved and threatened both in English and German. Had it not been for his injuries he would doubtless have struck his prisoner in the face. At length, after giving various instructions to von Kloster and Unter-leutnant Diehardt, he ordered the prisoner to be removed.
"The rascals look like being right," thought Alec on finding himself again in the cell. "Either this U-boat returns to Zeebrugge, or she does not. If she doesn't, it means that she'll be strafed properly. The Huns seem keenly alive to the possibility."
The Sub had not been very many minutes alone, when the seaman returned with his clothes. Giving a sort of superior smile, the fellow placed the bundle on the floor, and, without a word, backed out and relocked the door.
A brief examination showed that the Hun had broken the compact. He had Alec's wristlet watch, but no attempt had been made to dry the things. The uniform and underclothes were almost as wet as when Alec had arrived on board the U-boat.
Two hours later the submarine blew her ballast tanks and rose to the surface. The electric-motors were cut off, and the surface petrol-engines started and coupled up. All immediate danger was past, and the U-boat once more shaped a course for Zeebrugge.
Presently Seton was given another bowl of so-called soup and a piece of black bread. One taste of the former was sufficient. It was excessively salt. The bread, too, had a saline taste, and was as dry as sawdust, but Alec derived some relief to his burning throat by slowly chewing the unpalatable substance.
