"I'm going to kill you," said Lantry.
"Nobody kills anybody," said the man.
"Not any more they don't. But they used to, in the old days."
"I know they did."
"This will be the first murder in three hundred years. I just killed your friend. I just shoved him into the fire lock."
That remark had the desired effect. It numbed the man so completely, it shocked him so thoroughly with its illogical aspects that Lantry had time to walk forward. He put the knife against the man's chest. "I'm going to kill you."
"That's silly," said the man, numbly. "People don't do that."
"Like this," said Lantry. "You see?"
The knife slid into the chest. The man stared at it for a moment. Lantry caught the falling body.
