"That is precisely what I desire to find out," I answered. "When did you see him? How did you identify him? Why did—"
"I have something to tell you, if you will only be quiet, and let me speak," he interrupted. "It was, as you know, late last night before I left here, and for that reason, and also because I was perplexed and troubled, I walked fast—faster than even is my wont. The road was very lonely; I scarcely met a creature along the road, flooded with the moonlight. I never was out on a lovelier night; I had never, even in the country, felt I had it so entirely to myself.
"Every here and there I came within sight of the river, and it seemed, on each occasion, as though a great mirror had been put up to make every object on land—every house, every tree, bush, fern, more clearly visible than it had been before. I am coming to my story, Hal, so don't look so impatient.
