The Right of Way, Volume 3 by Gilbert Parker

All day John Brown, ex-clergyman and quack-doctor, harangued the people of Chaudiere from his gaily-painted wagon. He had the perfect gift of the charlatan, and he had discovered his metier. Inclined to the picturesque by nature, melodramatic and empirical, his earlier career had been the due fruit of habit and education. As a dabbler in mines he had been out of his element. He lacked the necessary reticence, and arsenic had not availed him, though it had tempted Billy Wantage to forgery; and because Billy hid himself behind the dismal opportunity of silence, had ruined the name of a dead man called Charley Steele. Since Charley's death John Brown had never seen Billy: he had left the town one woful day an hour after Billy had told him of the discovery Charley had made.

From a far corner of the country he had read the story of Charley's death; of the futile trial of the river-drivers afterwards, ending in acquittal, and the subsequent discovery of the theft of the widows' and orphans' trust-moneys.
