Greta Ohlsson and Hercule Poirot in “Unfinished Business”

There is a higher justice than the rule of law, monsieur.

Hercule Poirot

Then you let God administer it, not you!

And when He doesn't? When He creates a Hell on Earth for those wronged? When priests who are supposed to act in His name forgive what must never be forgiven? Jesus said, "Let those without sin throw the first stone."

Hercule Poirot

Oui.

Well, we were without sin, monsieur. I was without sin!
