Hit Man was originally a series of short stories, and while it still reads that way, it is a wonderful book. And, yes, guys, if it seems familiar, I understand several of the Hit Man shorts were originally published in Playboy.
The stories are about Keller, who is actually a hit man. Although the concept is such that you would think the main character was unlikely, Keller is likable. Perhaps it's his meticulous planning, or his slightly cynical view of life, but whatever it is, Keller is a wonderfully likable character.
Each of the stories has Keller facing a different dilemma, and handling them all with emotional maturity, although some might argue that it's really a lack of maturity. These stories made me laugh, and think, and I was very sad when the book ended.
Rather than give away the plot of each of the short stories, and ruin it for someone else, let me just say that this is my favorite Block book. Block has written a ton of books, and they are all good, but this is his best.
