I love the No. 1 Ladies' Detective Agency series. You cannot beat the series for a mystery with a change of pace from the usual whodunnit. The pace of life, and different attitudes makes for a book that can transport you to a different place.
Having said that, while this was a very entertaining book, I found it fell just slightly short of previous books in the series. Not that I think that anyone reading this book in isolation would notice, but there were some earlier themes I expected to be continued in this book, which were not. For example, very little mention was made of the orphaned brother and sister that Precious Ramotswe and her husband adopted.
Not that there is usually a major crime to solve in these books, but there was one "whodunnit" that I guessed very early on, largely due to the blurb on the back of the book. That's a bit of a shame!
Overall, though, this was every bit as enjoyable as the rest of the series.
