Root of All Evil: 6 (Locust Point Mystery)

Marriage can be murder. Kays first real case as a licensed investigator is to track down a suspected mistress and the possible hidden assets of an estranged husband. It all seems pretty routine but when the financial trail leads Kay down a rabbit hole of laundered money and bank fraud a boring divorce case gets interesting. Just as Kay closes in on what seems to be the white collar crime of the century the husband drops dead in his morning coffee--coffee that has more than just cream and sugar added to the cup! The the mans widow is the main suspect but Kay wonders if the murder is less a crime of passion and more one of greed--or even revenge.
