Avallone published over thirty Ed Noon books over thirty years, two-thirds of them focusing on Noon as a wisecracking private eye and about one -third featuring Noon as a super secret agent who answered only to the President himself. I have found overall the private eye novels to be if the highest caliber and the spy novels in the series to be somewhat of a lower caliber.
Shoot It Again, Sam is probably the craziest spy novel you will ever read. It leaps around between what seems like a crazy LSD type trip to the transport of a coffin on a railroad to hobnobbing with Hollywood's elite and some time with the man in the White House. It's light reading. It's goofy. It's kitschy. It takes the reader on a journey into the world of Sam Spade and Peter Lorre.
The story, while fun to read, lacks an overall coherence and at times is simply silly stream of consciousness stuff. But, it's Ed Noon and no Ed Noon novel is ever bad. He's the goofiest, most wisecracking private eye ever.
