Query: The worst Rat

The Stainless Steel Rat series has hit rock bottom. I will probably never read another Harrison book after this stinker. I love all the other books, especially the first four, but this one really put me off. Where are the Jim's daring escapes and mind-boggling cons? This book was one of the worst books I have read in the last five years.
