tasteful 'mind candy'

I'm currently reading the 3rd book in the No. 1 Ladies Detective Agency series. Its a really well written series set in Botswana. Precious Ramotswe owns this agency and we follow her continual adventures including trying to trace the origins of a boy doesn't appear to talk (and smells of lion) found in the bushes. I really recommend it. Start with the first book to get the background of how it all starts. Very easy reading, and what I would consider as gourmet 'mind candy'.
