The author on getting hooked on Flann O’Brien, reassessing Kingsley Amis, and why his grandfather was outraged by Watership Down

My earliest reading memory
Not my earliest reading memory, exactly, but my earliest memory of reading with avid enjoyment: The Three Investigators mysteries, a series of kids’ books about three juvenile detectives operating in far-off California (impossibly glamorous to me at the time) under the benign direction of Alfred Hitchcock, of all people. I devoured the first 12 in the franchise.

My favourite book growing up
Like everybody else growing up in the 1970s, I had a copy of Watership Down by Richard Adams on my bedroom shelves – it was the law. I did love it, though. Whatever fondness I have for the English countryside probably comes from that book. I remember my grandfather – a real country dweller – seeing me reading it and being outraged. “A book about rabbits?” he shouted. “They’re vermin!”
