Picking up from an unfinished manuscript of his late father, Graham Gordon Landrum, Robert Graham Landrum follows the further adventures of the ladies of the Daughters of the American Revolution in the quiet little town of Borderville, Tennessee.

When Mrs. Marguerite Claymore, a leading horticulturist, is found bludgeoned to death in her garden, the residents of Borderville are up in arms. A respected member of society noted for her many contributions, Mrs. Claymore seems to have been the least likely candidate for such a terrible crime.

It appears that Mrs. Claymore interrupted a thief in the process of looting her house. A teenage boy stands accused of the crime, and his family enlists the spunky octogenarian sleuth Harriet Bushrow to clear his name. Harriet soon finds several people from Mrs. Claymore's past who may have had a reason to do away with the often cantankerous and dictatorial old woman. A string of unsolved robberies may also be connected.

In The Garden Club Mystery, Robert Landrum pays a unique tribute to his father by co-creating the magic of the fictional town of Borderville and its much-loved characters.
