You know I'm a huge fan of the Number 1 Ladies Detective Agency series. I was a fan of the books long before there was talk of a TV series. Last year's TV-movie was wonderful; now there's a (sadly short) series on BBC.
The TV movie was very faithful to the first novel; it left out only the long flashback about Mme Ramotswe's father's years working in the mines. The series is not a straight adaption, but most of the details are recognisable from the novels; they've just been mixed-and-matched, and in some areas details are different.
( Thoughts about the changes, diversity and race in the series - cut for length )
