If the “cosy catastrophe” is the archetypal post-WWII English SF story, surely the quiet invasion comes a close second (The Midwich Cuckoos or Quatermass II being prime examples). They’re quiet because they either occur in an isolated location (a cut off village in Cuckoos) or by hiding in plain sight (an industrial processing plant in Quatermass II). John Christopher’s The Possessors (first published in 1965) is of the former type, being set in a ski-chalet high in the Swiss Alps, which is further isolated from its nearest village when an avalanche blocks the one mountain road leading to it.
At first, the holidaymakers (all Brits, having chosen this chalet for the English-American couple who run it) continue as normal, expecting the pass to be cleared in a couple of days. They’re a hung-up bunch, many of them recovering (or not recovering) from a variety of losses: Jane Winchmore is a widow in her thirties, Douglas Poole is on the rebound from an abruptly ended affair, while hostess Mandy Hamilton left the three children from her first marriage behind in America. Others have clear compromises or unbalances in their relationships: plastic surgeon Selby Grainger is the eternal dallier-with-women, while his wife, the cooly beautiful Elizabeth, puts up with it, confident he won’t actually leave her, and Ruth Deeping clearly favours her younger son Andy over ten-year-old Stephen, whom she constantly nags. Perhaps the only fully happy one of the bunch, in fact, is eight-year-old Andy, so beloved by his mother, which is perhaps why he’s the first victim of the alien invasion. Thinking he’s found a glowing blue ball in the snow, he touches it and instantly drops to the ground. Selby declares him dead, and he’s put in a makeshift coffin in the cellar—only for him to get up and leave the chalet sometime in the night. Everyone joins in the search, though only his mother, Ruth, has any faith that a boy in so few clothes and no shoes can survive for any length of time in the snow. But he does return—only, not quite himself. Significantly colder to the touch and slightly less human, he has (as we, the readers, know from the book’s opening section) been taken over by an alien spore, flung out from its dying home planet millions of years ago, which landed by chance on the Earth and was uncovered by the recent avalanche.
The alien—symbiotic or parasitic, depending on whether you take its point of view or ours—needs to isolate the humans, one by one, so as to infect them. And of course the humans take a long time working out what’s happening, speculating first of all that it’s some new kind of illness, or an infectious mass hysteria, or even demonic possession. And all the time, the survivors are becoming increasingly besieged in the chalet, boarding themselves up against the possessors trying to get in, get them alone, and take them over.
For most of the book the story is driven by suspense and the increasing tensions between the already flawed characters. In this, there’s an obvious contrast to be drawn between the aliens (who work effortlessly together, and tempt in at least one character with the promise of an end to human struggles) and the humans, whose only working relationships are those founded on long-held compromises. Chalet owner George Hamilton, for instance, is a good husband to his wife Mandy because he ignores the bottles of gin she’s got stashed about the place, and is pretty much an alcoholic himself. (There’s a lot of drinking in the book. Interviewed in a special issue of Interzone, Sam Youd—the real name of John Christopher, and meant to rhyme with “cloud”, apparently—admitted: “It’s the way I live, yes, I do drink alcohol, and quite a bit of alcohol, though only wine…” Though it seems to have been pretty much part of the times anyway.)
It’s hard not to compare Christopher with his contemporary John Wyndham, both of whom were the face of general-readership SF in Britain at the time. Christopher’s characters are much more evidently flawed, and come with a greater dose of cynicism about human relationships, a sense that there can never be anything more than a “total failure of comprehension” between people. Offered the slightest sign of sympathy for her widowhood, young Jane just wants to escape, and instantly regrets it the one time she shares her feelings of despair with someone else. The sense is that isolation and compromise are built-in to the human condition, whereas the characters in, say, Day of the Triffids, though they have to overcome external difficulties and the occasional dangerous human, will eventually find some sense of community, even family, in the end. For Wyndham, decency is a struggle but a worthwhile one; for Christopher it feels, at times, like a lost cause.
But there are resonances with other SF-horror, too. The most obvious to me was The Thing, for its icy setting and its alien that takes on human form, but also for its sense that if the invasion isn’t stopped here, the whole of the human race is at risk: “there can be no question of toleration between it and us. We have to wipe it out, if we are not going to be assimilated by it.” Invasion of the Body Snatchers is another, as is one of my favourite Doctor Who serials, The Horror of Fang Rock (where, as here, the isolation is prolonged by a lingering thick fog).
It’s certainly a suspenseful read, and I’m surprised it hasn’t been filmed (it was optioned, apparently), because it could surely be made on a reasonable budget. (Special effects: one glowing blue sphere.) It perhaps has less of the weird feeling I might have liked—I’d have preferred more of what seems to be promised by the German translation of the book, titled Die Unheimlichen (“The Uncanny Ones”). This is far more of an adventure/disaster tale (and the cast of flawed characters, each with their cross to bear, recalls the set-up to so many 70s disaster movies), and a successful one, at that. I’d definitely like to read more by Christopher. I’ve been meaning to read The Tripods since around the end of the 1970s…
