" Artifice and reality, he thought, examining the photographs and drawings, they combine more easily than we realise. TV shows pretend to offer realism but they hide as much as they show. Fiction, on the other hand, can contain fundamental human truths. And sometimes it’s possible to step back and forth between these two worlds just by opening the correct door, by finding the key that will unlock mysteries. So much of London is masked; unspoken rules protect the privileged, unseen codes hide the guilty. What a crafty lot we are! "
