In this instalment of the charmingly entertaining adventures of Botswana’s premier female detective, it’s going to take all Precious Ramotswe’s intuition and eminent sensibility to crack her toughest case yet: the decade-old disappearance of an American on the edge of the Kalahari.

What’s more, she must attend to concerns closer to home: the promotion of her secretary Mma Makutsi to the dizzy heights of Assistant Detective; her impending marriage to the wonderful Mr J. L. B. Matekoni; the trouble caused by his unscrupulous maid; and the unexpected arrival of not one but two additions to the Matekoni family.
