Tea Time for the Traditionally Built is the tenth book in Alexander McCall Smith's series The No. 1 Ladies' Detective Agency.
I normally don't read much past the third book in a series. Usually the characters and premise of a story peters out for me after two or three books. That is not the case with The No. 1 Ladies' Detective Agency series. (Okay, I haven't read the series straight through from book 1 - 10 and beyond, but I have read several of them ad hoc, so I feel reasonably comfortable in my statement.) Smith's stories and characters for The No. 1 Ladies' Detective Agency become increasingly rich and complex as the series moves on. Plus, they make me wistful for Africa and the contentment of enough pumpkin to eat and cup of hot bush tea. (Actually, bush icetea is my go to caffeine free drink - but it's not the same)
I've read some other of Smith's books and while enjoyable, The No. 1 Ladies' Detective Agency is really his wheelhouse.
