With a pleasurable feeling that he was getting his own back for the sand-bagging affair, Villiers saw the burly German measure his length on the deck as the result of a straight left with the Englishman's fist. For the present Siegfried Strauss ceased to count in the unequal contest. Three or four of the crew ran on with a rush. Villiers didn't stop to meet them. He was cool enough to realize, in the first sense of elation, that there are limits to human powers. Running aft, he paused only to unship a life-belt and hurl it overboard, then, with the leather case still grasped in his right hand, he leapt over the rail into the sea. He hit the water with tremendous force, for the _Zug_ was steaming at a good twelve knots. That and his still weak condition almost deprived him of breath. He swallowed a good half-pint of salt water before he rose spluttering to the surface. Even while he was still under the surface Villiers found himself debating upon the wisdom of his rash act. "If I hadn't jumped into the ditch," he soliloquized, "those fellows would have slung me in, and perhaps given me another tap on the head just to make things doubly sure. I told friend Strauss that I was good for a hundred yards. So I am at racing-speed. It is now up to me to see if I can cover four or five miles, hampered by a leather bag and a life-buoy." Why he hung on to the attaché-case he hardly knew. Whatever there was within it was evidently now no secret to the directing spirits behind the s.s. _Zug_. Even if Harborough's charts and plans were still inside the case, there was every reason to suppose that they had been duly inspected and the information they contained committed to memory. Sir Hugh knew the locality of the wreck, even without the aid of the stolen documents, so, now that the mischief was done, there could be little good served by regaining them. The attaché-case was well made and the lid fitted closely; consequently it possessed a considerable amount of buoyancy. On coming to the surface Villiers found that he could support himself by the case without much effort, and thus give himself time to take stock of his surroundings. Fifty yards away floated the life-buoy. Having assured himself of his position, the swimmer devoted his attention to the _Zug_. Already she was a good cable's length away, and holding on without apparently altering course. Five or six of the crew were standing right aft, and Villiers fancied that he caught the dull glint of the barrel of a rifle. "They'll put about," he thought, "and either run me down or else put a bullet through my head if they spot me. I don't think they do, although I'm right in the glare of the sun. I'll keep clear of that buoy for a time, though."
