Now, if you're not familiar with Mr. Gischler's work, let me just say that I bought his novel, Gun Monkeys, sometime ago because I heard it was a hard-boiled tale with hitmen. Hitmen? Hard-boiled? Those are two things right up my alley, so you better believe I got a copy. At that time, I was reading the likes of Raymond Chandler, Ross MacDonald, and Dashiell Hammett. I wanted to see if this Gischler-guy could write entertaining hard-boiled, hitman, crime fiction. He did! I absolutely loved that book. Since then, I've picked up a few of his other books: The Deputy and Shotgun Opera. I you're a fan of hard-boiled crime fiction, you should do yourself a favor and read Gischler. I doubt you'll regret it.
