I’ve never been into shoplifting, though I once had a friend who was. And, no, before you ask, I’m not using that old ‘friend’ device to hide my own identity. She was a girl I met at university. Bookshops were her hunting ground. I’m assuming she was driven by some sort of compulsion because she couldn’t enjoy the books she nicked and — she assured me — God would always punish her by making a contact lens drop out of her eye within hours of the crime.
