The Full Cupboard of Life — Alexander McCall Smith

In the fifth book in the prodigiously successful series, traditionally built, eminently sensible Mma Precious Ramotswe continues her enterprise at the No. 1 Ladies' Detective Agency in Gaborone, Botswana, a country that is indeed fortunate.

Still engaged to the estimable Mr J.L.B. Matekoni, Mma Ramotswe understands that she should not put too much pressure on him, as he has other concerns, especially a hair-raising request from the ever persuasive Mma Potokwane, matron of the orphan farm. Besides Mma Ramotswe herself has weighty matters on her mind. She has been approached by a wealthy lady to check up on several suitors. Are these men interested in the lady or just her money? This may be a difficult case, but it's just the kind of problem Mma Ramotswe likes and she is, as we know, a very intuitive lady.
