"That's right, you coward! You'll need it," said Harris. He squeezed the man with all his might. Out of the tail of his eye he caught the glint of the other German's knife as it descended. Releasing his hold upon the one man, he stepped quickly backward. But the knife caught him a glancing blow on the forehead, inflicting a deep wound. For a moment Harris paused to shake the blood out of his eyes. Then, with a smile playing across his features, he advanced; and as he advanced he said: "You've done for me, the lot of you. But I shall take you with me." The Germans quailed at the look in his face; and as he moved forward swiftly they threw down their knives and turned to run. But they had delayed too long. Harris stretched both hands out straight before him. One hand closed about the arm of the German to his right. The other clutched the second man by the throat. Harris pulled the man he held by the arm close; then released his grip, but before the German could stagger away, seized him, too, by the throat. "Now I've got you," he said. Blow after blow the Germans rained upon his face and shoulders, kicking out with their feet the while. Harris paid no more attention to these than he would have to the taps of a child. But the Englishman felt his strength waning fast. It was with an effort that he staggered across the deck. At the rail he paused for a moment, gathering his strength for a final effort. Then, still holding a German by the throat with each hand, he leaped into the sea. Once, twice, three times the three heads appeared on the surface and a spectator could have seen that Harris retained his grip. Then the three sank from sight. And so passed the former pugilistic champion of the British fleet, brave in death as he had been in life. The waves washed over the spot where he had gone down. CHAPTER XXX THE UNKNOWN UNMASKS With the coming of dawn the three figures in the little motor boat gazed back in the direction from whence they had come. There they could still make out the distant shape of the _Bismarck_. She rode quietly in the water, and there was nothing about her appearance to tell the three in the motor boat of the terrible struggle that was raging even at that moment. "Poor Harris," said Jack. "I hope that in some manner he is able to escape." "Certainly I hope so, too," declared Frank. "He's a brave man," said von Ludwig. Jack drew the fateful deck of cards from his pocket. "These," he said, "I shall keep." He ran through the deck several times, playing with them. Unconsciously he counted them. There was something wrong. Jack counted the cards again. The result was the same. "Sir!" he called to von Ludwig. "Well?" "How did you chance to have this pack of cards?" "I play solitaire considerably," was the reply. "You couldn't have played solitaire with this deck," said Jack. "Why not?" "All the cards are not here. There are but fifty-one."
