Face the Raven
"Forget the way you usually look at the world. This street’s going to be hiding in plain sight. If you see something unusual or notable, dismiss it. Just keep walking. But if there’s a bit of London so unremarkable that you don’t even think about it, stop. You could very well be standing right outside a trap street. Count everything that you see. Because when you hit the area around a trap street, it’s very likely you’ll lost count. You’ll lose count because the misdirection circuit is creating confusion in your mind. Details won’t add out. Reality will have glitches in it. Like when you try to read the same simple sentence three times over, and the meaning just won’t sink in."
