The man gave chase, calling to us with a string of imprecations to stop. But Hal only ran the faster, though after a street or two he slackened, and the man gained on us a little. So we continued, the distance between us and our pursuer now a little more, now a little less. People turned and stared at us. A few boys, scenting grim fun, followed shouting for awhile; but these we soon out-paced, till at last in deserted streets, winding among warehouses bordering the river, we three ran alone, between long, lifeless walls. I looked into Hal's face from time to time, and he was laughing; but every now and then he would look over his shoulder at the man behind him still following doggedly, and then his face would be twisted into a comically terrified grimace. Turning into a narrow cul-de-sac, Hal suddenly ducked behind a wide brick buttress, and the man, still running, passed us. And then Hal stood up and called to him, and the man turned, looked into Hal's eyes, and understood. He was not a coward. Besides, even a rat when cornered will fight for its life. He made a rush at Hal, and Hal made no attempt to defend himself. He stood there laughing, and the man struck him full in the face, and the blood spurted out and flowed down into his mouth. The man came on again, though terror was in every line of his face, all his desire being to escape. But this time Hal drove him back again. They fought for awhile, if one can call it fighting, till the man, mad for air, reeled against the wall, stood there quivering convulsively, his mouth wide open, resembling more than anything else some huge dying fish. And Hal drew away and waited. I have no desire to see again the sight I saw that quiet, still evening, framed by those high, windowless walls, from behind which sounded with ceaseless regularity the gentle swish of the incoming tide. All sense of retribution was drowned in the sight of Hal's evident enjoyment of his sport. The judge had disappeared, leaving the work to be accomplished by a savage animal loosened for the purpose. The wretched creature flung itself again towards its only door of escape, fought with the vehemence of despair, to be flung back again, a hideous, bleeding mass of broken flesh. I tried to cling to Hal's arm, but one jerk of his steel muscles flung me ten feet away. “Keep off, you fool!” he cried. “I won't kill him. I'm keeping my head. I shall know when to stop.” And I crept away and waited. Hal joined me a little later, wiping the blood from his face. We made our way to a small public-house near the river, and from there Hal sent a couple of men on whom he could rely with instructions how to act. I never heard any more of the matter. It was a subject on which I did not care to speak to Hal. I can only hope that good came of it.
