Lawrence Block brings back Keller, the amoral but likable assassin who is also the protagonist of Block's earlier novel HIT MAN. In HIT LIST, Keller travels to Louisville, Kentucky to carry out a routine job (murdering a businessman and making it look like a suicide), but he soon realizes that his own life is in danger. The tables have been turned on this killer-for-hire, and now Keller has to find out who has put a price on his head, and why.
