The back courtyard was filled with towering geometric shrubbery, joined at impossible angles like an M.C. Escher drawing. A topiary maze. Grinning. I walked lazily around its perimeter until I found a narrow opening. The path was long and straight for some ten meters, and then split off in four directions. Intuitively, I made a hard right turn, then two lefts. I hit a dead end. I thought I had gone back the way I had come, but I encountered a strange fork in the pathway. I went right. Another dead end. I was getting irritated. I stood still for a moment while my abandoned flesh punched some serious deck. And then I was running. I flew through the maze, the green walls becoming a blur as I went faster and faster. In a shower of leaves, I was out.
