Mma Ramotswe’s business, the No. 1 Ladies’ Detective Agency, has clients but needs to cut costs and increase revenue from fees. To reduce costs, she and her fiancé Mr JLB Matekoni decide to move the agency to the garage, which has plenty of office space. The original office will in turn be let, to add income. Mma Makutsi, secretary, is given the title of assistant detective, with a rise in pay. Mr JLB Matekoni is behind on his paperwork, which Mma Makutsi can organize. He has been lethargic lately. Mma Ramotswe realizes he needs help, and sets out to help him. He will not agree to see the doctor, so Mma Ramotswe asks Mma Potokwane of the orphan farm to step in. Mma Potokwane brings him to Dr Moffat who diagnoses him as having depression, for which he steps back from his garage while medications begin to work. Mma Makutsi takes over management of the garage and the useless young apprentices, making the apprentices accountable for their work, and making rapid business decisions to make good on the garage’s name, Speedy Motors. She shows her strong management skills from the first hour of taking over her role as acting manager. The young apprentices are impressed with her, and how she applies her detective skills to solving some of the auto problems that the apprentices cannot solve.
