For those of us who get a kick out of spying on other people’s bookshelves, the last few weeks have offered an embarrassment of riches. Whole Twitter accounts have been set up for the sole purpose of scrutinising the titles that famous people choose to display in the background during their televised Skype calls. The point of the game is not to find out the books people are reading, but the books they want to be seen to be reading. Some people are more sporting than others, acknowledging the rules of the game and knowingly playing along.
