At the comic site, you will see a tab (below the comic) "Family". Click there and then hit the "About" tab above the top of the Comic and you will get a precis of the four main characters. You can also go to the "Archive" to follow the entire length of the comic. Worth your attention.
Cheers for that! I’ve just worked my way backwards to December 12 2008 for some context. It’s a good cartoon! I’m going to work my way all the way back to 2002 in my spare time, and put it on my regular reading list.
Thanks for your help: I must have sounded rather thick not “getting” today’s cartoon.
FRegards!
