Harry and Ellie became friends over the next few years. He showed her how to throw knives and stones and other objects with pinpoint accuracy, and though she didn't seem to have his knack for making things happen by wanting them, she got pretty good at it. She reciprocated by showing him how to hide in plain sight—how to keep to the backs of crowds, how to watch for the moments when people were distracted, how to divert attention with his body language, how to dress in colors and combinations that wouldn't catch the eye, how to keep to the shadows, and above all, how to look like he knew exactly what he was doing no matter how he felt inside.
