The No. 1 Ladies' Detective Agency often helps people find things they have lost. But they have never had to help a client find herself—until now, in this latest installment of Alexander McCall Smith's best-selling and beloved series.
 
A kindhearted brother and sister have taken in a woman known only as “Mrs.”—a woman with no memory of her name or of how she came to Botswana. And so it's up to Precious Ramotswe and her new co-director, Grace Makutsi, to discover the woman's identity.
 
Meanwhile, motherhood proves to be no obstacle to Mma Makutsi's professional success. As she settles into her role as partner at the agency, she also launches a new enterprise of her own: the Handsome Man's De Luxe Café, a restaurant for Gaborone's most fashionable diners. But even Miss 97 Per Cent isn't fully prepared for the temperamental chefs, drunken waiters, and other challenges that come with running one's own business. Help may come from an unexpected source, if only Mma Makutsi can swallow her pride and ask.
 
And next door to the No. 1 Ladies' Detective Agency, Mr. J.L.B. Matekoni is all too familiar with the difficult decisions of business owners. He is finally forced to make a tough choice, one that will bring major changes to both Tlokweng Road Speedy Motors and the No. 1 Ladies' Detective Agency—and that will require all of Mma Ramotswe's finesse and patience to sort out.
 
With sympathy and indefatigable good humor, Mma Ramotswe and her friends see one another through these major changes and discover along the way what true friendship really means.
