Sweet Deal Appealed

Donut Lady's life depends on her memories of her conniving ex-husband. The silent stalker intends for her to die.
The past haunts the Donut Lady when her dead husband's sketchy brother arrives in town. He had blocked her appeal for her conviction of the murder of her manipulative ex-husband. What's he doing in her hometown? To add to her troubles, her self-designated protector, Jack, is arrested for assault on the taunting, no-good ex-brother-in-law who is later found dead in Jack's yard.
Where does a counterfeiter fit in the puzzle? Only the dead husband knows.
