Recently, I started reading Pete Dexter's magnificent "Deadwood" and I must say—the book predates the TV series of the same name by a decade—it is without a doubt the source material for the HBO TV series.
Here for your reading pleasure is a random sampling of just a few of Dexter's poignant and "dead on" Deadwood comments from the first fifty pages of the book:
"And Bill laid his eyes on him again, calm and cold, until he went away. That was the way Bill handled annoyances when he could. He never threatened a soul unless he meant it."
