Reader, I apologise/apologize

Did I say it has to be non-fiction? I've just read (in a sitting) the latest Inspector Montalbano and am about to read (in two sittings, I imagine) the latest Wallander. It's a bank holiday so I'm not at work and could be at my desk writing. But, lo, I'm not. Others might clean the kitchen by way of procrastination but I'm lazier than that.
