Martin Valliant by Warwick Deeping

For a long while Martin Valliant neither moved nor spoke, and Mellis watched him in silence. His rage had passed, and a kind of wondering horror dulled his eyes. He was afraid of his own handiwork, this death that he had brought into the world, these bloody things at his feet. And yet they fascinated him, for there were two men struggling in Martin Valliant-the poor monk and the soldier.

The monk in him, being the elder, stood shocked to the heart, and most tragically dismayed. Such a bloody deed as this seemed the end of everything, even though it had been done in generous wrath. Martin's monastic soul shrank away, horrified, covering its face with its hands. He had spilled blood, he was a murderer, he had sinned against the God Who had given him life.
