The Miracle at Speedy Motors by Alexander McCall Smith

The sleuths of The No. 1 Ladies' Detective Agency in Gaborone, Botswana take on two new cases--one professional and one personal. Mma Sebina hires Mma Precious Ramotswe to find her real parents while both Mma Ramotswe and her assistant Mma Makutsi are trying to unmask the culprit who has been sending them nasty letters. In their personal lives, Mma Makutsi is ecstatic over the fact that her fiancee Mr Phuti Radiphuti has bought her a bed with heart-shaped red velvet headboard, but complications ensue and minor tension develops between Mma Ramotswe and her husband, Mr J.L.B. Matekoni over his decision to take their adopted daughter, Motholeli to South Africa for a cure that might make her walk again. As usual, everything is resolved favorably with McCall Smith's mix of cozy charm and great sense of place.
