Based on Alexander McCall Smith's passionate and poignant book series, 'The No. 1 Ladies' Detective Agency' chronicles the adventures of Precious Ramotswe, the eminently sensible and wise proprietor of the only female-owned detective agency in Botswana. Aided by her highly-efficient yet rather peculiar secretary Mma Makutsi, Mma Ramotswe investigates cases, helps people solve problems in their lives, and begins a special friendship with the highly respectable owner of a local garage.
