“Saturdays it's as regular as early closing,” answered the woman, “but you might have to wait a bit.”

“I'll wait in your room, granny, next Saturday,” suggested Hal.

“All right,” agreed the woman, “I'll risk it, even if I do get a bloody head for it.”

So that week end we sat very still on two rickety chairs listening to a long succession of sharp, cracking sounds that, had one not known, one might have imagined produced by some child monotonously exploding percussion caps, each one followed by an answering groan. Hal never moved, but sat smoking his pipe, an ugly smile about his mouth. Only once he opened his lips, and then it was to murmur to himself: “And God blessed them and said unto them, Be fruitful and multiply.”

The horror ceased at last, and later we heard the door unlock and a man's foot upon the landing above. Hal beckoned to me, and swiftly we slipped out and down the creaking stairs. He opened the front door, and we waited in the evil-smelling little passage. The man came towards us whistling. He was a powerfully built fellow, rather good-looking, I remember. He stopped abruptly upon catching sight of Hal, who stood crouching in the shadow of the door.

“What are you doing here?” he demanded.

“Waiting to pull your nose!” answered Hal, suiting the action to the word. And then laughing he ran down the street, I following.

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.
