That's cool! Actually, it's sort of the same way with the Cat Who series too. I actually just picked one up when I saw it, and didn't realize there was a whole series! Turns out the first book I read was kinda in the middle (The Cat Who Moved a Mountain). So you can skip around and read the books, or start from the beginning. Once I found that out, I started from the beginning and read them all! Don't ya just love cat mysteries??!!
