"Feel my pulse and tell me," said he. "Steady as a rock, but devilish cold. A little thrust and parry'll warm you. Here we are, and there's your man and his second waiting." The boat scraped the rushes and the waterman held it while the two men scrambled on to the bank. The ground was fairly well chosen for the purpose. It was a tolerably firm piece of turf about a hundred yards long by some twenty broad and almost as smooth as a bowling green. It was the only solid piece of earth for some distance, all around being at a lower level and boggy. Not forgetful of the usual courtesies, the combatants bowed and took off their coats and vests. It was then that Vane caught sight of Rofflash. "You're the fellow whom I knocked down on London Bridge on a certain night some little time ago," said he. "The very same," rejoined Rofflash with a grin which made his ugly face still uglier. "You took me unawares. If you've the mind to try conclusions a second time, fair and square and no surprises, by God, sir, I'll be pleased to oblige you when you've despatched Mr. Dorrimore." The bully's braggart manner and sneering voice made no impression on Vane. The suspicion that he was the victim of a plot was strengthened by the presence of Rofflash and his words. For ought he could tell Jarvis might be in the conspiracy too. But there was no way out of the trap, and turning on his heel, he walked to his ground. The duel began. The combatants were about equal in youth, height and build; in skill they were unfairly matched. Vane was comparatively a novice in the use of the "white arm." Dorrimore, on the other hand, was a practised swordsman, though he was not so accomplished as he fancied he was. The two, after the preliminary salute, advanced to the attack. Dorrimore handled his weapon with a slightly contemptuous air, as if he did not think it worth while to take much trouble over so inferior an opponent. To a certain extent he was right. Vane, however, was shrewd enough to see that this carelessness was but assumed, and he did not take advantage of one or two opportunities of thrusting given him by Dorrimore, evidently with the intention of leading him into a trap. So they went on cautiously, their blades rasping against each other, and neither man gaining any advantage, although once or twice Vane found his antagonist's weapon perilously near his body. Then all at once Dorrimore changed his methods. He began fencing in earnest, and so rapid was the play of his sword that the eye could scarcely follow it. Suddenly he muttered an oath as a red stain appeared on his arm. Vane had been lucky enough to scratch him, probably more by accident than dexterity.
