In this seventh installment in the internationally bestselling, universally beloved series, there is considerable excitement at the shared premises of the No. 1 Ladies' Detective Agency and Tlokweng Road Speedy Motors .
A cobra has been found in Precious Ramotswe's office. Then a nurse from a local medical clinic reveals to Mma Ramotswe that faulty blood-pressure readings are being recorded there. And it looks as though Aunty Emang, the advice columnist in the local newspaper, may not be what she seems.
It all means a lot of work for Mma Ramotswe and her inestimable assistant, Grace Makutsi, and they are, of course, up to the challenge. But there's trouble brewing in Mma Makutsi's own life. Her greedy uncles are demanding an extra-large bride price from her well-to-do fiancé, a man of substance, Phuti Radiphuti, and though money may buy her that fashionably narrow (and uncomfortable) pair of blue shoes, it won't buy her the happiness that Mma Ramotswe promises her she'll find in simpler things - in contentment with the world and enough tea to smooth over the occasional bumps in the road.
