"Honest, Jim," said the girl, "I waited half an hour. I thought you weren't coming."
"Let that lady alone," said Peter. "She's with me."
He didn't like Elaine any more, but he knew that the code demanded that he should show resentment of the intrusion.
"Keep your face out of this," said the newcomer. "What damned business is it of yours?"
There was a ready-made answer for that in the code.
"You come outside and I'll make it my business," said Peter.
"Don't waste your time on the big souse, Jim," said Elaine clutching at the arm of the man who had threatened her. But the fact that the girl absolved Peter from all the cares of guardianship did not remove his responsibilities according to the code. "Come on outside," he repeated. He went slowly up the stairs but when he reached the sidewalk and turned around there was no Jim. Peter waited. He wanted very much to hit somebody and Jim seemed wholly appropriate. After a few seconds the man came out. He walked up close to Peter but he held his hands behind his back. According to the code nothing could be done until each had extended an arm.
"Come on," said Peter impatiently, "put up your hands and I'll punch your head off."
Jim suddenly drew his right arm from behind his back and clipped him sharply over the head with a bottle. Peter stared at him wonderingly for almost a second. Surprise seemed to halt the message to his brain. Slowly he crumpled up on the sidewalk. The blow was not painful, but the swinging arc of all things visible was now longer than ever before. The lights, the lamp-posts and the buildings slowly turned end over end in a complete circle. Peter put one hand to his head. It was wet and sticky. For a second or so he considered that and wondered. Finally he realized that it was blood. Lifting himself up on his hands and knees he saw Jim and Elaine scrambling into a taxicab.
"I'll bet she doesn't talk about right angles to him," thought Peter. For a moment he considered pursuit, but before he could make up his mind the taxicab had started. It swept past him no more than ten feet away. He could see the red head of the woman in the window. One week later he decided that he should have cupped his hands and shouted, "You hypotenuse hussy!" That night he could think of nothing. The fragments of glass lay about him. Peter examined them and found it had been a champagne bottle. After a bit he called a taxicab for himself and said, "Go to some hospital that's near." He had begun to feel a little faint.
