“bowie is dead”. The three-word Facebook message — all lowercase — somehow reaches me on a barely-functional wifi network on the jetfoil between Korea and Japan. I get a burst of adrenalin, a surge of horror. Can this be a joke? If it is, it’s in very bad taste. I try to load the BBC News site on my phone. No joy. Try it on the MacBook Air. After much groaning and gurning the headlines finally load. Nothing about Bowie. It must be a hoax. I remember something Iman once said: “David doesn’t believe anything until it’s reported on the BBC.” I make a mental note to unfriend the joker. But then Twitter sputters into life. I manage to get half a page of my feed. One of the tweets is from Duncan Jones, Bowie’s son. It’s true, he says. There’s a photo of Bowie hoisting him onto his back. Duncan is going offline for a while, he says.
