Howard W. Campbell Jr.'s story

This is the second book I've read by Vonnegut (after the exceptional Cat's Cradle) and Vonnegut Proves his superior ability to create complicated characters. After finishing the book, I still have no idea if Cambell was a real person or not. (I do not think so, but the author made him feel like a real person.) My only complaint is indeed the plot which never CLEARLY defined and it Constantly shifted in time. But other than slight lack of focus (Which works in a way since it is the last written words of a probably soon to be convicted was criminal about to be hanged Possibly, making the story all the more realistic.) Overall this was a great book with all issues: such as morality and responsibility. In fact, I loved the idea did a man working as a spy Could Serve the side he is spying on far more than he ever Could Serve the ones he is spying for ... all unintentionally. Vonnegut loads the story with humorous ironies so.
