I’m at an event in Brixton with authors Lauren Beukes and Ben Percy. It sold out weeks ago, but it’s not very big, so I’m expecting a relaxed evening. It’s an overnight trip, because my experiences of trying to get out of Brixton late at night to make the last train have been grim. One time someone tried to stop me getting the last Tube by throwing themselves under it.

Okay, maybe that wasn’t specifically to spite me. But still.
