The story began with an introduction of the case:
Flora poisoned her alcoholic husband, inheriting his wealth and becoming the wealthiest woman in the village.
There was also the wealthiest man in this village, named Roger.
Roger's wife had died many years ago.
Perhaps both of them had lost their spouses and empathized with each other, so they fell in love.
Roger planned to marry Flora.
Before marriage, Flora told Roger: "I killed my alcoholic husband. This secret is known by someone in the village who has been continually threatening me with it recently and has extorted a lot of money from me."
Roger was shocked.
He was a just person, unable to accept that the woman he loved had murdered her husband.
Although he did not plan to report Flora, their engagement ended without a hitch.
However, Flora was still the woman Roger loved deeply, so he asked Flora: who was the one secretly extorting her behind her back?
He wanted to help Flora get out of this trouble.
