Professor Olive Twist has come to Zinnia, Mississippi to study a mysterious grave wherein lies the Lady in Red, a perfectly preserved and stunningly beautiful but unnamed and unclaimed body. Olive claims she can not only identify the corpse, she can also prove the woman’s scandalous role in the nation’s history. Olive takes it a step too far, though, when she starts connecting elite Zinnia families with the same scandal.

Dander up, Zinnia’s society ladies know only one way to handle Olive: they call on the private investigative services of Sarah Booth Delaney. But Olive’s real agenda is clear as Mississippi mud, and when Sarah Booth discovers a present-day dead body, she knows there’s more than just family pride and Southern heritage at stake. If she can’t find the murderer and fast, it might just be Sarah Booth's life on the line next.
