Sage is hot-headed and impulsive while her twin, Tabby, is calm and collected, making them the perfect partnership. When one of their customers at Savannah's Book and Candle Shop is found murdered, from a blow to the head, that partnership is put to the test. Taking on their very first case, the twins need to keep their employee, Gerald, from taking the blame. The witnesses and the medical examiner aren't talking, however, and worse, Tabby and Sage have found a clue that could seal Gerald's fate.
