"Perhaps that was my fault, but he had been delirious for a day and night; and in the afternoon, when he was calmer, I went to sleep. One is apt to sleep too long when one is tired. When I wakened he was not in bed and a whisky bottle I had taken from him was nearly empty. I think he must have disturbed me as he moved about, because when I went outside I saw him making for the river. I ran, but I came too late, and you know the rest." "You are not to blame," said Thirlwell. "You have twice taken pity on a man who tried to starve you. He meant you to die of hunger the night he stole into your camp." "He is dead. One must be charitable. What would he gain by leaving me to die?" "Don't you know?" Thirlwell asked. "We can talk frankly now the matter has been taken out of our hands. When he got better after the first attack, the time I kept watch with you, he had probably some remembrance of his ravings. Anyhow, I expect he remembered he'd got a fright and may have talked. He thought you knew too much." "It's possible," said Father Lucien, very quietly. Thirlwell was silent for a few moments and then resumed: "I hesitated about going to his help. We were heavily loaded, the risk was great, and I thought Miss Strange's life worth more than his. She made me go and I believe I could have saved him, but he saw her and let himself sink. She declares he looked afraid!" "It is very strange." "I don't find it strange," said Thirlwell. "There's a touch of dramatic justice about the thing that appeals to me. I suppose you know what day it is? _Driscoll knew_." Father Lucien shook his head. "What is one day more than another, when all wrongs are put right and crimes punished in the end? Justice is not theatrical, but the obstinate offender cannot escape." He paused and then resumed: "Well, we shall never know all that happened, and as you have said, the matter is no longer in our hands. Perhaps for the girl's sake--" "Yes," said Thirlwell, "she has borne enough. You can imagine the shock she'd get if we found out, and had to tell her. The thing's done with. It's some relief to feel that my responsibility has gone." Father Lucien made a sign of agreement. "I will come to see her to-morrow," he said, but Thirlwell knew that Agatha would never learn from him that Strange's canoe had not been accidentally capsized. Early next morning Thirlwell went to the tail-pool, but nothing except some driftwood washed about in the eddy. The latter had worn out a deep hollow and he scrambled over the rocks in order to look down into its revolving depths. There was nothing there, and when going back he made his way across some worn slabs that had been covered until the water sank to an unusually low level. By and by he stopped at the edge of a pool. A small round object that was not the color of the stones lay at the bottom.
