Thirlwell knitted his brows. He had dark suspicions, but after all they had no solid foundation, and he thought it best to copy the missionary's reserve. "We know Driscoll's character, and may have been mistaken about one thing. Is it logical to imagine that such a man would feel afraid?" "Fear sometimes comes without remorse," said Father Lucien. "Superstitious fear, working on a brain disordered by liquor and illness?" "We will not argue about the proper name. It may be superstition, or something greater. I believe that retribution follows the offense." Thirlwell looked hard at the other. "Well, I doubt if we will ever know the truth about Strange's death." "It is possible," Father Lucien agreed. "Perhaps it is not important whether we know or not. One thing is certain: if wrong has been done, it will be made right, if not by the way we would choose, by another. I think we may leave it there." "We must," said Thirlwell dryly. "There is nothing else to do. In the meantime, if I can't be useful, I'm going to sleep." Day was breaking when he wakened and Father Lucien told him that Driscoll was better, but would need careful nursing for a time. "Then Scott must come to-night," Thirlwell replied. "I've had enough of watching Steve, and don't mind admitting that your charity is greater than mine." When he reached the shack he told Scott nothing about what he had heard, because he thought Father Lucien would sooner he did not. The latter knew when to be silent and it would do no good to talk about the matter unless something happened to throw a light upon the mystery. On the whole, he was relieved when Driscoll, who soon recovered, set off up river with a half-breed and a loaded hand-sledge. CHAPTER VI FATHER LUCIEN'S ADVENTURE The snow was firm and the rivers were frozen hard when Thirlwell left the mine with two _Metis_ trappers to examine an outcropping reef that one of the half-breeds had told him about. He was not very hopeful, but agreed with Scott, who thought it might be worth while to look at the reef, since the specimens the _Metis_ had brought showed traces of silver and lead. Then Father Lucien had gone to visit some of his people who had camped for their winter trapping far up in the bush, the shack was lonely, and the frost hindered the work at the mine.
