World's End by Richard Jefferies

In these days such a verdict and such an ending to a tragedy would be out of the question; but there were no police in those times to take up a case if it chanced to slip by the Coroner. Once past the Coroner, and the criminal was practically safe. The county officers were never in a hurry for such prosecutions, for a gallows cost at least £300. They wanted a public prosecutor then ten times more than we do now. Sibbold was shunned by the very men who had acquitted him; but there is no reason to suppose he ever felt remorse. He was made of that kind of stuff of which the men in armour, his ancestors, were composed, who thought little or nothing of human life. But one day he met Arthur, his eldest son, face to face upon the stairs. It was the first time they had met since the inquest -- Arthur had avoided the place, and wandered about a good deal by himself, till some simple folk began to think that it was he who had committed the deed, and that his conscience was troubling him.

This meeting on the stairs took place by accident one morning -- Sibbold was going to pass, but Arthur put his hand on his shoulder, "I saw you do it," he said. He had just entered the rick yard when the shot was fired. He had held his peace, but his mind could not rest. "I cannot stay here," he said, "I am going. I shall never see you again."
