The fluorescent lights in the Piggly Wiggly were humming that high, jagged sound that always made my teeth ache. I was standing in line with two cans of tomato soup, a roll of paper towels, and a bag of coffee. Leonard was outside in the truck, parked right in the fire lane, watching the glass doors like a hawk. He liked to see me move. He liked to time me. If I went over twenty-three minutes, he would find some reason to touch the back of my neck until I went numb.
