In most detective novels, we see intelligence and smartness as primary traits in protagonist(s). Though Precious Ramotswe is both, she is first and foremost a kind woman. Her ways of dealing with her clients is with gentle words and heaps of kindness. From there she uses her observational powers and intelligence to progress her case. 
 Without the twists that one is accustomed in Agatha Christie novels - or any books in this genre, Ramotswe's progress has more leg work, thinking out of the box and being persistent in her pursuit of the truth while the rampant sexists and misogynists try to shut her down or vilify her efforts. Disgruntled attitude isn't just from the men. A client who is looking for proof for her husband cheating ways downright accuse Precious of being "husband stealer" when the said proof is provided. The lady detective takes it in her stride and does what she believes is her calling - being a detective. 
 McCall Smith uses the slowly modernizing Botswana as a backdrop, its culture transitioning between memories of days spent in South Africa and finding its own footing in the world with men finding new jobs home and women stepping out of their zone to do their own thing. Interactions between Ramotswe and officers in government, hospitals and other private sectors explores nuances of this culture. Smith's writing is gentle and gives Precious every bit of respect she deserves. 
 Its what one needs after a long week of work. A cup of tea and one of this books. Time well spent. 
 3.5 stars because I adore Precious.
