Bradley toiled on, chained heavily to the idea of his hatred and his vengeance, and thinking how he might have satiated both in many better ways than the way he had taken. The instrument might have been better, the spot and the hour might have been better chosen. To batter a man down from behind in the dark, on the brink of a river, was well enough, but he ought to have been instantly disabled, whereas he had turned and seized his assailant; and so, to end it before chance-help came, and to be rid of him, he had been hurriedly thrown backward into the river before the life was fully beaten out of him. Now if it could be done again, it must not be so done. Supposing his head had been held down under water for a while. Supposing the first blow had been truer. Supposing he had been shot. Supposing he had been strangled. Suppose this way, that way, the other way. Suppose anything but getting unchained from the one idea, for that was inexorably impossible.
