Mma "Precious" Ramotswe's comfortable existence as the only detective in Botswana is rattled when a certain Mr. Buthelezi opens the Satisfaction Guaranteed Detective Agency. Mr. Buthelezi's brochure advises, "Don't take any chances! Entrust your enquiries to a MAN!" As if this development isn't enough, Precious has also taken on two difficult cases, one of which hits close to home. But with wisdom and common sense on her side -- and plenty of bush tea -- she figures to crack both cases and upstage her competition.
