When I started writing that story, I didn't know there was going to be a Ph.D. with a wooden leg in it. I merely found myself one morning writing a description of two women I knew something about, and before I realized it, I had equipped one of them with a daughter with a wooden leg. I brought in the Bible salesman, but I had no idea what I was going to do with him. I didn't know he was going to steal that wooden leg until ten or twelve lines before he did it, but when I found out that this was what was going to happen, I realized it was inevitable.
