A locksmith on Thames Street kept six keys he would never sell. He let you choose one. He never once let you keep it.
Lock your eyes on one key.
Learn the shape of its bow. Count its teeth. Read the Latin word beneath it. Do not touch the keys. They are not yours.
Take your hand away from the glass.
Say your word three times, silently. Picture its teeth.
Your key has left the rack.
Five remain. Count them. Read every word. Yours is not among them, and nobody touched a thing. Least of all you.
