Life is good for "Garden Girl" Gloria Rutherford. Spring has finally sprung, love is in the air, and no dead bodies have turned up in the small town of Belhaven--lately. It seems as if it's almost too good to be true. Just as Gloria starts to get settled into her familiar routine, she receives a mysterious message from her older sister, Liz. Certain that her sister, the drama queen, is once again bent on turning Gloria's life upside down for no good reason, she almost chooses to ignore the dire message that she may be in danger. When a key to her sister's place shows up in her mailbox after Liz mysteriously vanishes, Gloria jumps in with both feet to track her down. Crisscrossing the country with one of the other Garden Girls in tow, the two amateur sleuths find themselves on an adventure of a lifetime. Gloria soon discovers her sister's mysterious disappearance is the least of her worries.
