After the broadcast of Curtis’s 2007 film The Trap, which traced the influence of game theory – the idea that humans behaved as self-interested individuals – on contemporary economic thought, Prospect magazine’s Max Steuer argued that the series “greatly exaggerates the power of ideas, and at the same time almost wilfully misrepresents them”. Others made similar criticisms of All Watched over by Machines of Loving Grace, which linked the anti-state philosophy of Ayn Rand with the “techno-utopians” who developed modern computing. At the very least, don’t his films encourage precisely that gloomy feeling – a sense that power is in the hands of an unaccountable elite – that so exercises him?

“Well, I am a creature of my time,” he concedes. We’ve found our way to a café in the shopping centre near Thamesmead, where we can chat at greater length. “What I’ve been trying to do is analyse why progressive ideas failed.

“Secondly, I’m interested in telling stories, because I like telling stories and I think ideas are important. I take particular influences of particular groups of people as a way of showing how that idea spread out. I never say this is where it all came from, this shadowy group of people. I’m telling you a story, like a novelist would, but as a factual story to try and bring it to life to you.”

I thought about the break-in, his absences, the dead sister, the fingerprinting . . . but what did it all add up to? Was he a victim of circumstance-or a serial killer? Was I his next target? I became obsessed with getting answers. Then I searched the most obvious place of all: Google. I typed in the name “Dino Smith,” and a couple of clicks later, there it was. His mug shot, on the America’s Most Wanted Website. He was a suspect in the biggest jewel heist in San Francisco history. I gaped at the screen in disbelief, then ran in circles, howling obscenities: “Fuck fuck fucking shit fuck fucker! Holy FUCK!”

The argument that says the UKIP represents a rebellion against the political elite seems true (aside from its public school-educated/banker/professional politician leader), but even that lends it a sophistication it barely deserves. UKIP is the road rage of a repressed parochialism; the collective panic attack of an introspective minority that has watched a succession of socially and economically liberal governments and their co-religionists in the media promote a world-view that seemed to leave these “outsiders” further and further in the margins.

The margins of culture, that is. Not the margins of the economy. One suspects many of UKIP’s leading figures are businessmen and women who have done rather well out of the post-Thatcher economic consensus. Conversely, UKIP supporters from poorer parts of society are not disadvantaged because of EU red tape, immigration or tolerance towards gays, but because they live in a low-skill, wildly free market economy that has been propagated by every government – to a greater or lesser extent – since 1979, creating an entrenched inequality that is worsening every year.

“Fools!” said West, his clenched fist striking the lectern before him. “We must prepare today’s youth for a world whose terrors are etched upon ancient clay tablets recounting the fever-dreams of the other gods-not fill their heads with such trivia as math and English. Our graduates need to know about those who lie beneath the earth, waiting until the stars align so they can return to their rightful place as our masters and wage war against the Elder Things and the shoggoths!”
