The Alexander McCall Smith fan letter announces that, starting March 29, HBO is running 'The No. 1 Ladies' Detective Agency' series based on his books. He says they've made a "good job" of it.
I really like his site, BTW, even with the music in the background (there's an obvious "off" switch at the upper right). It's attractive, simple, and seems to do a good job of communicating what he and his books are like. If you are in New York and can get to the RTO event, it's going to be something.
