It is one thing, however, to catch a man by the throat, and another to retain that grip, especially when your antagonist happens to be an International football player. To Tom this red-bearded rough, who charged him so furiously, was nothing more than the thousands of bull-headed forwards who had come upon him like thunder-bolts in the days of old. With the ease begotten by practice he circled his assailant with his long muscular arms, and gave a quick convulsive jerk in which every sinew of his body participated. The red-bearded man's stumpy legs described a half-circle in the air, and he came down on the stone pavement with a sounding crash which shook every particle of breath from his enormous body. Tom's fighting blood was all aflame now, and his grey eyes glittered with a Berserk joy as he made at Ezra. All the cautions of his father and the exhortations of his mother were cast to the winds as he saw his enemy standing before him. To do him justice, Ezra was nothing loth, but sprang forward to meet him, hitting with both hands. They were well matched, for both were trained boxers and exceptionally powerful men. Ezra was perhaps the stronger, but Tom was in better condition. There was a short eager rally--blow and guard and counter so quick and hard that the eye could hardly follow it. Then a rush of railway servants and bystanders tore them asunder. Tom had a red flush on his forehead where a blow had fallen, Ezra was spitting out the fragments of a broken tooth, and bleeding profusely. Each struggled furiously to get at the other, with the result that they were dragged farther apart. Eventually a burly policeman seized Tom by the collar, and held him as in a vice. "Where is he?" Tom cried, craning his neck to catch a glimpse of his enemy. "He'll get away after all." "Can't 'elp that," said the guardian of the peace phlegmatically. "A gen'elman like you ought to be ashamed. Keep quiet now! Would yer, then!" This last at some specially energetic effort on the part of the prisoner to recover his freedom. "They'll get away! I know they will!" Tom cried in despair, for both Ezra and his companion, who was none other than Burt, of African notoriety, had disappeared from his sight. His fears proved to be only too well founded, for when at last he succeeded in wresting himself from the constable's clutches he could find no trace of his enemies. A dozen bystanders gave a dozen different accounts of their movements. He rushed from one platform to another over all the great station. He could have torn his hair at the thought of the way in which he had allowed them to slip through his fingers. It was fully an hour before he finally abandoned the search, and acknowledged to himself that he had been hoodwinked for the third time, and that a long week would elapse before he could have another chance of solving the mystery.
