Excerpt
For the fraction of a moment I could not remember where I had known the man who addressed me so jovially. My way of knocking about the world brought me into contact with so many people that it was difficult to sort my gallery of faces, and keep each one mentally ticketed. But after a second or two of staringthrough that convenient medium, my monocle, I was able to place the man who had accosted me. He was a rich mining king from Colorado, by the name of Harvey Farnham, whom I had met in Denver, when I had been dawdling through America three or four years ago.
