Business is slow at the No. 1 Ladies' Detective Agency, so slow in fact that for the first time in her estimable career Precious Ramotswe has reluctantly agreed to take a holiday. The promise of a week of uninterrupted peace is short-lived, however, when she meets a young boy named Samuel, a troublemaker who is himself in some trouble. Once she learns more about Samuel's sad story, Mma Ramotswe feels compelled to step in and help him find his way out of a bad situation. Despite this unexpected diversion, Mma Ramotswe still finds herself concerned about how the agency is faring in her absence. Her worries grow when she hears that Mma Makutsi is handling a new and rather complicated case. A well-respected Botswanan politician is up for a major public honour, and his reputation is now being called into question by his rivals. The man's daughter has contacted the No. 1 Ladies' Detective Agency to investigate these troubling claims, but, as in so many cases, all is not as it seems. In the end, the investigation will affect everyone at the agency and will also serve as a reminder that ordinary human failings should be treated with a large helping of charity and compassion.
