If a civil servant’s job sounds vague, doesn’t quite add up or comes across as so boring you can’t bring yourself to ask any questions about it (ahem, Chandler), that might just be for a reason. ‘Nobody ever comes up to you and says, “Hi, I’m John, I’m MI5.” They say, “Hi, I’m Tom, I’m from logistics.”’ Then, it’s up to you to do the snooping. For example, you might notice, like Glass, that ‘there is no logistics and Tom isn’t Tom’. However, beware: ‘Speculation is frowned upon,’ says Glass. Plus, even a trained pro like her may never fully grasp the truth. ‘I don’t know if anything they told me was true,’ says Glass. ‘It’s like trying to walk on water. Everything looks normal, but you kind of sink with each step, you don’t know anything and you’re talking to people who know everything.’
