Early on, Camellion is captured and a skin sample is taken. Dr. Blore-Lewellyn plans to create a whole regiment of Death Merchants, all of whom will have the same cunning and skill of the original. (Fortunately, for the time frame of the book, the doctor has also perfected a way for the clones to grow into adults in only three weeks!)
Invasion of the Clones is a below-average entry in the Death Merchant series. The evil doers are not very evil, the fight scenes and shootouts are pedestrian, and the climax of the adventure is perfunctory. It's Rosenberger-by-the-numbers. (The book is also littered with typos.) The promising idea of Camellion battling five clones of himself never gets off the ground, fizzling as Camellion dispatches them almost immediately upon seeing them.
But Rosenberger does let Camellion ramble on about various aspects of American society, in what I presume is an echo of the author's right-wing views. In a conversation with Dr. Mbiti of the Freedom Fighters, a group opposing Garbu, Camellion "[gives] it to Mbiti with both verbal barrels":
Many people in our government in Washington are so black-oriented that the blacks can do no wrong. The situation is often unrealistic, with white workers, holding years of seniority, being laid off in preference for blacks. Brilliant white students are being turned away from college and universities in preference for blacks with mediocre scholastic ability. All in a quest for balance. . . . You've called me a racist, Dr. Mbiti. I'm not. I'm simply a guy who believes that the concept of equality must also imply equal responsibility. But "equality" doesn't mean that in the U.S. It means handouts and preferential treatment for any person whose skin is black.One of Garbu's henchmen, a Nazi war criminal named Gerhard Boldt, holds similar views. Boldt is described as "an extremely intelligent man" who muses about "black loafers ... and other violence-prone minority trash" and refers to the the U.S.'s "black-ape-loving government" whose civil rights programs have wrecked society. (The book was published in 1976.)
Examples of Rosenberger's goofy writing style are (sadly) minimal, but here are a few:
"[I]t is characteristic of the human self to reflect upon experience and to use its precepts as material for the construction of a concept."Also: During a shootout early in the book, Rosenberger stops in the middle of the action to go off on a tangent about myrrh and frankincense (both of which are exported by Korlumba). Rosenberger also describes various cuts of lumber (1½ x 8 x 12 and 1 x 3 x 6).
"Just as no man can kill time without injuring eternity, so it is that men who do not stumble over mountains but over mole hills of unpreparedness."
"In five times the amount of time it takes to say 'The ragged rascal ran around the ragged rock', the underground resistance fighters swarmed over the machine gun nests ..."
"A truly wise man never plays leap-frog with a unicorn."
CIA man Vallie West (who has appeared in previous DM books) flies weapons and ammo into the jungle for Mbiti's Freedom Fighters, and at one point comments to Camellion: "You remind me of a man caught with his pecker in a meat grinder." ... I did like one of Camellion's quips: "The narrower the mind, the broader the statement".
In addition to the shootouts, Camellion also engages in some hand-to-hand combat, assaulting various goofs and boobs with martial arts: "a jabbing multiple-finger Nukite ax-stab" and a "Kaiko Ken open-knuckle strike". (Rosenberger also alludes twice to a character from one of his other action series: a Kung Fu expert named Mace, who is "half-Chinaman, half-white man".)
