The No. 1 Ladie's Detective Agency (Broché)

The one with Charlie's big secret. As the temperature rises in Gaborone, Precious Ramotswe wonders whether the heat could be the reason that business is particularly slow. But then a distant cousin comes to the agency with a plea for help. Armed with Mma Ramotswe's circumspection and Mma Makutsi's sharp eye, the ladies decide to pursue the issue together. What, after all, could be more straightforward than a family matter ? Meanwhile, their colleague Charlie is behaving oddly, borrowing Mma Ramotswe's van and returning it in an unusual condition.
Digging a little deeper, the explanation is both strange and extraordinary, and takes Charlie, along with Mma Ramotswe's husband, Mr J. L. B. Matekoni, on a hair-raising night-time expedition.
