Bay Tanner is a young widow and aspiring private in­ves­ti­ga­tor from wealthy South Carolina stock. When a hitherto unknown shirt-tail cousin (fifth half cousin, specif­i­cal­ly) bursts into Bay’s life, she brings havoc in her train.

As one of the characters says, the plot sounds like a made-for-TV movie. Still, Bay is a feisty heroine and the background is not one that has been mined deeply.
