Sweet and warm, as all No. 1 Ladies' Detective Agency books are. Of course, because the protagonist is a thoughtful, caring lady, in her own right.
In this installment in the series, the most pressing concern is not the mystery - which involves a soccer team - but what is happening with Mma Ramotswe's beloved car. That sounds ridiculous when written down, but Smith is able to imbue actual emotion into that part of the story! I did also like what ended up solving the mystery, though, as it was both banal and amusing at the same time.
Also, you learn a small bit more about her relationship with her husband and her kids, which is welcome because if there's anything lacking in these books, it's details about that.
