The great hippopotamus hotel - Alexander McCall Smith

A chance meeting with the manager of The Great Hippopotamus Hotel leads the much-admired and traditionally-built Precious Ramotswe to investigate what is going wrong with this previously successful country hotel. Guests have been unwell, clothing has disappeared from the washing line, and scorpions have found their way into the guest bedrooms. Mma Ramotswe drives out to the hotel with her irrepressible colleague, Grace Makutsi (97 per cent in the final examinations of the Botswana Secretarial College). What they find there are family conflicts that only the investigators of the No. 1 Ladies' Detective Agency will be able to resolve.

Meanwhile, at Tlokweng Road Speedy Motors, Mma Ramotswe's husband, Mr J.L.B. Matekoni, gets a visit from a middle-aged client who wants to purchase a fast Italian sports car. What should the conscientious garagiste do in such circumstances? Should the client's wife be told? Mma Ramotswe is used to wrestling with such tricky questions, but it is harder for Mr J.L.B. Matekoni.

And in the background is that beautiful country, Botswana, with its wide skies and its courteous people. In such surroundings, big problems soon seem small, and small worries fade away altogether.
