The Adventures of the Stainless Steel Rat is an omnibus edition of the first three Stainless Steel Rat books (self titled, Revenge, Saves the World), all featuring Slippery Jim deGriz, best thief in the galaxy. A high-tech bandit in a society where perfect law enforcement means that criminals are very few and very skilled, deGriz steals because he's bored with a bunch of high-tech gadgets and simple cons, avoiding killing people at all cost. His skills and ethics get him recruited into the Special Corps, the real secret police, run by former thieves.
On the plus side, when the books work they really work. Slippery Jim always has a new identity, a clever plan, a non-lethal solution that has a lot of chaos and him walking safe and sound through the middle of it. It's high-action and high-octane.
The downside is that the stories get increasingly lazy. I quite enjoyed the first one, where deGriz is recruited into the Special Corps and tracks down a psychotic con artist who built an ancient battleship in plain sight and then slipped right out of his clutches. But the next two books have less cleverness and more straight up non-lethal violence with sucker punches, sleep gas, and smoke grenades as he goes after militarists trying to conquer the galaxy and a time travelling megalomaniac. Some parts of the book haven't aged well at all. Angelina, deGriz's first enemy and than wife after Special Corps conscience surgery, is positively cringe worthy. This might also be the first time I've been concerned about a fictional character's alcoholism, as deGriz works his way through bottle after bottle. I've heard that authors who drink while writing have their characters drink to excess, and it sure feels like the drink or two Harrison had as he did the daily writing turned into a drink on every other page, punctuated with epic benders. A lot of fun, but ultimately fluff that never quite becomes first rate.
