Marriage can be murder.

Kay's 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 man's 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.
