The No. 1 Ladies' Detective Agency is a series of novels by Scottish author Alexander McCall Smith. The agency is located in Gaborone, capital of Botswana. Its founder is a Motswana woman, Mma Precious Ramotswe, who features as the stories' protagonist and main detective. Mma is a Setswana term of respect for a woman; the equivalent term for a man is Rra. The episodic novels are as much about the adventures and foibles of different characters as they are about solving mysteries. Each book in the series follows on from the previous book. They have been adapted for radio and television.
