While the office of the agency still shares the building with the Speedy Motors Garage (run by Mma Ramotswe's husband, Mr. J.L.B. Matekoni), lots of new developments have occurred. Mma Makutsi and Phuti Radiphuti have become parents, Mr. J.L.B. Matekoni decides to become a "modern husband," and Charlie the apprentice reveals a new side of his personality.
But even with all these new and exciting developments, there are still cases to be solved. The main case this time involves an inheritance matter. Mma Sheba, a lawyer, is attempting to fulfill the bequests in a will left by a local farmer who has recently "become late." The man left his farm to his nephew, who used to come from a neighboring country to spend the summers with his uncle, but the lawyer is not at all convinced that the young man who has stepped forward to claim the estate is who he says he is.
