As he gained the bulging deck of the pirate craft, Seton, steadying himself by the guard-rail, turned to bid good-bye and good luck to his men. Guessing his intention the unter-leutnant gave a curt order. Instantly two German sailors laid hold of the British officer; and without ceremony took him below. In the act of descending the vertical ladder, Alec caught sight of Count Otto von Brockdorff-Giespert and the kapitan of the U-boat. Both were vastly enjoying the British officer's discomfiture. Count Otto, in spite of his injuries and dishevelled appearance, was smoking a cigar and holding a steaming cup of "coffee substitute". "I owe this young Englishman a debt," he remarked grimly to the commander of the U-boat. "I will take good care that I repay it with interest." It was the Prussian touch all over. Von Brockdorff-Giespert totally ignored the fact that his foes had saved his life. He attributed his misfortunes mainly to Sub-lieutenant Seton, as if the latter had been actuated by feelings of personal animosity rather than sheer devotion to duty. Already the Hun had made up his mind to inflict every possible indignity upon the prisoner. Confined in a cramped, ill-ventilated and ill-lighted compartment in close proximity to the wireless-generator-room, Seton strained his ears in the hope of finding out what had happened to his whaler's crew. The purr of the electric motors and the noise of men's voices echoing and re-echoing in the interior of the huge metal cylinder deadened all sounds from without. The U-boat was submerging. Apparently she had not used her guns upon the boat, for the recoil of the weapons would have been noticeable. There was, however, the horrible possibility that, before diving, the submarine had deliberately rammed the boat. Or, perhaps the Huns had shot down every man in the whaler by rifle and pistol. That was one of Fritz's little stunts--cold-blooded butchery. After a while Alec thought it was time to look after himself, since his captors evidently had no intention of attending to his personal comfort. The warmth of the cell caused the moisture to steam from his saturated clothes. Divesting himself of his garments he wrung them out, and began to exercise his limbs to ward off the numbness that assailed them. Presently the door of his cell was thrown open and a seaman appeared carrying a bowl of hot soup. "Can I have my clothes dried?" asked Alec. "It's not my work to dry the clothes of a schweinhund," replied the fellow in English. Then he pointed to the Sub's wristlet watch. "For that I will dry your things," he added. "Right," replied Alec. "It isn't going, though. The water's spoilt it." "That is to be expected," rejoined the German, picking up the saturated garments. Then waiting until Alec had handed over his watch, he went out, to return presently with a canvas suit, rust-marked and greasy.
