The Limpopo Academy of Private Detection

• Mma Precious Ramotswe: Owner of the No. 1 Ladies' Detective Agency in Gaborone, Botswana, now in her 40s. She is self taught as a detective, and generally successful in resolving the cases brought to her. In her youth, she married a musician who was cruel to her. She had a baby who died soon after birth, and learned she could have no more children. She is married to Mr. J.L.B. Matekoni. She drives a tiny white van which she bought back after briefly using a newer van. She is a woman of "traditional build" and one who values the traditions of her people even as her country changes so much.
• Obed Ramotswe: Late father of Precious, who was a strong and wise man. She loves him dearly and often thinks of him.
• Mr. J.L.B. Matekoni: Owner of Tlokweng Road Speedy Motors garage, and possibly the best mechanic in Botswana. He is the husband of Mma Ramotswe; they were married at the end of the fifth novel, The Full Cupboard of Life. He is a good man.
• Motholeli: One of two foster children being raised by Mr. J.L.B. Matekoni and Mma Ramotswe. Due to early health problems she moves about in a wheelchair. She was introduced in Tears of the Giraffe.
• Puso: Five years younger brother of Motholeli. He is a lively boy. He and his sister are of the Basarwa people of Gaborone, hunter-gatherers who live in the bush. He was introduced in Tears of the Giraffe.
• Mma Grace Makutsi: She is now the secretary to Mma Ramotswe and an associate detective. She is very efficient, known for scoring 97 on her final exam at the secretarial college. She wears large glasses. She has good insight into many situations, but lacks the ease in viewing life that marks her employer. She married Phuti Radiphuti in the previous novel, The Saturday Big Tent Wedding Party. She is in her early 30s.
• Phuti Radiphuti: He is the owner of a furniture company and of some cattle, who is married to Grace Makutsi. He displays his competence in contracts in the supervision of the construction of their new home.
• Mma Silvia Potokwani: Matron of the orphan farm outside Gaborone. She is a most persuasive woman, in seeking help for her orphans and keeping the place running, who has perversely been dismissed. She is friends with both Mr J.L.B. Matekoni and Mma Ramotswe.
• Thomas: Carpenter who works on the house under construction for Grace and Phuti Radiphuti. He is from outside Botswana and speaks with Phuti one evening when Phuti first comes to inspect the progress on their home.
• Violet Sephotho: Low scoring but attractive student at the Secretarial College when Grace Makutsi attended it. She is Grace's nemesis, and now has left a bad reputation behind her from her generally self-centered actions. She is the mistress of a businessman in this story.
• Charlie: An apprentice in the garage. He is in his mid 20s. He chooses to help Fanwell in a risky way, and does not understand the risks of what he did.
• Fanwell: The younger of the two assistants, who has completed his apprenticeship. He is the sole support of his grandmother and younger siblings. He is quiet in his manner, not a risk-taker.
• Chobie: Friend of Fanwell, known to Charlie, who asks Fanwell to repair a car he has. He proves not much of a friend once both have been taken by the police for dealing in stolen merchandise.
• Mr Ditso Ditso: A businessman in Gaborone who joins the board that oversees the orphan farm. He is married.
• Clovis Andersen: Author of the book, The Principles of Private Detection, which has been the guide for Mma Ramotswe and Grace Makutsi from the start of the detective agency. He lives in Muncie, Indiana in the US, and comes to visit a friend working in Botswana after his wife dies. He then greets the only private detectives in Gaborone, startled to learn they read his book and know it by heart.
• Mr Putumelo: Builder of the new home for Grace and Phuti Radiphuti. He builds well, but he is having them pay for the bricks for his own new house, which Phuti learns before the final reckoning.
• Mma Soleti: She runs a beauty shop, the Minor Adjustment Beauty Salon, in Gaborone, which Mma Ramotwse visits because of the offer of a free consultation, and finds she and her half-sister know about Mr Ditso Ditso, as his wife and his "secret sweetheart" both visit the half-sister's nail salon.
• Mma Soleti (Nails): She runs a nail salon in Gaborone and half-sister to the other Mma Soleti. She provides the final evidence to stop Mr Ditso Ditso's involvement with the orphan farm.

Critical reception for The Limpopo Academy of Private Detection has been mostly positive.^[2][3][4] The Guardian's Philip Womack wrote, "It is all but impossible to criticise this novel; that would be like kicking a slightly senile labrador that always retrieves a ball when you throw it, whether you like it or not."^[5] Publishers Weekly considers that this novel follows a pattern developed in earlier novels, and that "As always, the detection is secondary to Smith’s continuing exploration of the rhythms and social dynamics of smalltown African life."^[2] Kirkus Reviews adds that "Few fans, however, will want to miss the byplay between Mma Ramotswe and her revered mentor."^[3]

A review in The Scotsman notes that whenever Clovis Andersen "helps Mma Ramotswe, his principles for successful sleuthing deliver almost instantaneous results. . . because 'people will always give themselves away.'” The appeal is moral clarity: "these gentle stories of manners and morality have a clarity that is surely one of the reasons for their widespread appeal."^[6]

Mary Jane Smetanka wrote that the last few novels seemed boring with the same themes and main characters, but in this novel, she "was surprised to find new depths". Mma Ramotse's "musings on power, mortality and human frailty and foolishness seem more perceptive" and Grace Makutsi is "wrestling with guilt at her newfound status as the wife of a prosperous man". In sum, she says "The gentle and telling portrait of the human condition lingers".^[7]

This novel was on the New York Times hardcover fiction best seller list in 2012.^[1]
