IN THE TIME OF FIVE PUMPKINS

The No. 1 Ladies’ Detective Agency gets backed into accepting competing clients in the same case.

It’s a trying day for Mma Grace Makutsi, the agency’s self-anointed executive president for development, when not one but two visitors refer to her as a secretary. The first, Special Pest Services owner Mr. Excellence Modise, who wants the agency to confirm his fears that his wife is cheating on him, is “an extremely annoying man.” And it feels as though there’s something sketchy about the second, Mr. Freddie Mogorosi, the owner of a big franchise garage who wants to persuade Tlokweng Road Speedy Motors owner Mr. J.L.B. Matekoni, the husband of agency founder Mma Precious Ramotswe, to join a trade association to establish and enforce professional standards. The conflict arises when Mma Ramotswe and Charlie, the assistant who’s not quite a mechanic and not quite an investigator, shadow Aleseng Modise and find her in a compromising situation that’s not so compromising after all; she claims her husband’s the one who’s cheating on her and asks Mma Ramotswe to accept her as a client as well. The ethical conflicts are obvious, but since she owns the only detective agency in Gaborone, Mma Ramotswe feels honor-bound to represent both parties. Meanwhile, Mr. J.L.B. Matekoni’s adventures with Mr. Freddie Mogorosi expand to include a crocodile and a deadly snake, leaving him not so much frightened as bewildered. As usual in this celebrated franchise, the pace is leisurely, the felonies are minimal, the tone is reflective and the results are enchanting.

Although Mma Ramotswe concludes, “We are a detective agency—we are not menders of souls,” readers may well disagree.
