What timeline gaps? I may be too casual a listener to understand. I hear them chronologically in production order (mostly) and I'm stuck with the pirate story with the sixth. (no 40 or so?). Not my thing, that story. In general they are all of a good quality and I learned the word "twittle twattle". My favourite was with the sixth. I forgot the name, it was the one with that intelligence/child that always wanted to "kill kill kill." Was it The holy terror? It was so lovely.
