He polished the tooth of a tiny gear until it shone, replaced a broken tooth with a scrap from an old music-box, and oiled the pivot with a drop so small it was like adding a memory. When he closed the backplate, a faint music began to wind itself like a secret: not a full melody, but a pattern, a stitch in sound.
