In an age of catastrophe, humour is more important than ever, argues the satirical author.

I do not write historical fiction. But I envy those who do. I can picture them sitting in the lamp-lit halls of the New York Public Library on 42nd Street, thumbing through fraying, early 20th‑century telephone directories or spinning the roulette of the microfiche machine, or meeting at a nearby coffee dispensary with fellow history-minded wordsmiths in the wee hours of the day, like hunters getting ready to put a bullet through the heart of a wildebeest. The best are able to address the current moment through deft metaphysical journeys between the present and the past, to illuminate our wayward realities by reminding us that it has ever been so, that the past is not even the past, or whatever Faulkner said.

Personally, I have trouble building a literary time machine. A decade ago, when I wrote a memoir set primarily in the 1980s, all I could remember of that era was Michael J Fox running around in a varsity jacket. The rest of my memories were just volumes of mist that sometimes trickled out of my minor brain holes, tantalising but highly suspect emissions that bore news of events which may or may not have been. When one’s teenage years are a distant Greek island, imagine trying to write a novel about the romantic entanglements of the Italian futurists or the political cataclysms of Meiji-era Japan, or anything at all about the ancient Egyptians.
