(It's the fingers, Chick - they have a mind of their own.)
From earliest childhood, Ricardo Tiona wanted to be an engine driver. Nothing remarkable about that, of course - lots of little boys do. What set young Dic apart was his skill in choosing his parents, for the Tiona family were seriously wealthy. (His great-grandfather had been a circus acrobat, his grandfather a ring-master, and his father had sold the land his circus stood on for development as a major hub airport.) So what Dic got for his tenth birthday was not a model train set but a railway - the DicTionaRy.
