"It would be a very long time before anyone, especially in America, was ready for a terrorist hero" points out Lisa Tuttle in her introduction to this 1957 novel, as an explanation as to why Neil Gaiman never got around to making a movie of it despite purchasing the rights. And one can see her point. This is a novel one feels very guilty about enjoying.
The story is the basic wartime espionage plot. Lone secret agent is secretly dropped in the middle of enemy territory with instructions to cause mayhem and chaos, out of all proportion to his numbers - just like a wasp can cause a car crash without even using its sting. But the twist here is that this isn't an American or British spy operating in Berlin, or a Confederate agent operating in New York. No, the man in question is human enough - an Earthling (or "Terran" as the book has it) sewing discord and terror among the population of an alien confederation, a blue-skinned, pointy-eared, bow-legged race known as the Sirian Combine.
The war has reached a stalemate. The Sirians outnumber the Earthlings twelve to one, but our side (naturally) has superior technology and strategy. So James Mowry, who was born on a planet in the Sirian Empire, is dispatched to do his patriotic duty - which he proceeds to do with a vengeance, inventing an imaginary terrorist organization, assassinating high-ranking officials, and generally doing all he can to undermine the Sirian war effort.
And, as a reader, I couldn't help but cheer him along. After all, I am a "Terran," and if we ever get into a war against an alien race I'd sooner we win than lose. And one's sympathy is, naturally, with the lone, brave, hunted individual having to survive on his wits against a whole planet.
But all the time, there is a nasty thought at the back of one's mind. Mowry, you see, is a terrorist, and a particularly nasty, sociopathic one at that. He shows little remorse at the pain and injury he causes to the high-ranking enemies he kills, or the the innocent Sirians who also suffer in his wake. It does not help that despite their unearthly appearance, the Sirians seem to have families, jobs, likes, emotions and feelings just like us. Indeed, when visualizing the action in your mind, you'll find yourselves seeing them as earth-type humans, so familiar are their emotions and expressions.
It might be possible to defend this book as a piece of satire, deliberately lampshading the evils of terrorism, even in a "noble" cause, and Lisa Tuttle's introduction even suggests this. And to be fair, Russell has written some highly regarded anti-war stories. But somehow, the fact that he is so obviously enjoying himself telling the story works against this defense.
Russell describes Mowty's activities in lascivious, colorful detail. Like a slavering, trembling-with-secret-delight Fundamentalist Christian evangelist describing the filthy secret activities of homosexuals or the contents of a gonzo porn mag, it's clear to the intelligent reader that the author is actually enjoying the description of the evil activities that his hero carries out. Very little sympathy is wasted on the the victims, even those of lowly status (with one exception - an innocent elderly male, kicked to death by a Sirian cop, so of course it can be divorced from any guilt attaching to Mowry.
And by the end, half of your mind is glad that Mowry has succeeded, and "our" side has won - the other half is retching with disgust at what we needed to do to secure the victory! I would imagine that Americans might feel similar about the atomic bombs dropped on Nagasaki and Hiroshima, or the British about the bombing raids on Berlin.
Terry Pratchett has gone on record as saying he would have given anything to have written this work, and that he could not imagine "a funnier terrorists' handbook."
I have to admit, I found very little to laugh at in this story. I did, however, find it exciting, suspenseful and an excellently told adventure yarn. And it's hard to go by the fact that anyone living in a country in which basic freedoms have been won on the battlefield owes a debt to those that served "undercover" doing things that even ordinary soldiers could not bring themselves to do, in the service of their country.
Yes, I enjoyed it a lot. And stripping it of the star I would otherwise given it judged purely on its narrative value has totally failed to assuage my conscience.
