I'm not sure if it was twenty years or fifteen but apparently Ridcully didn't even notice. Perhaps that was because Esme tried so hard to be properly witchlike in her appearance. I would have liked for him to wonder a little. I just finished Lords and Ladies again this morning. It was a very satisfying read outside of that question.

I haven't read Wyrd Sisters in a loooong time so I don't know about this.

It was one of the most exciting things that happened in the book, you should read it again. One of the best things about the Discworld books is how well they stand up to being re-read.

I can't find it anywhere. I've read all my other ones at least 5 times.

Well I hope you find it again. I guess you know what I mean about being able to reread these books.
