It should have been a lovely summer afternoon.
When a violent death disrupts the Monthly meeting of the Pua Kala Garden society, Professor Molly Barda has no intention of playing amateur detective. But Molly's not just a witness–the victim is Molly's house guest and grad-school frenemy. And Molly quickly finds to her dismay that her interest in the murder of the stylish and self-centered Melanie Polewski is more than just...academic. The Black Thumb is the fourth installment of the Professor Molly Mysteries.
