That was one of Elmore Leonard’s 10 Rules of Writing. Number 6, I think.
Elmore Leonard died about six months ago. His career spanned over six decades. He was a prolific writer, and, in my mind, one of the best of his generation in what I would call the “pulp fiction” category. You know, the kind of mystery or thriller or suspense (whatever they were called back in the day) paperback you would pick up at your corner book store when you were looking for a good, fun, quick read.
