A historian on there tells the story of a man who left his village for several years of travel. An imposter turned up and claimed to be the man, and took up residence in the man's house and in his wife. Claims of him being an imposter are bandied about; but the wife claims that the stranger is her husband.

I'm guessing you know what happens next . . .

As the court was about to announce their verdict that the returnee was indeed Martin Guerre, another man turned up, also claiming to be Martin Guerre! He actually remembered more details of Martin's life than the first returnee did, and he had a much better (and more provable) story about where he'd spent the intervening years. The court then ruled that the second man was the real Martin, and sentenced the first man to death for fraud and adultery.

And of course the woman was properly charged for her lies? Yeah, right:

Earlier in the trial, the imposter Arnaud and Martin's wife Bertrand had independently recounted intimate details of Martin and Bertrand's life together. From this, the author Ms. Davis concludes - with some good evidence - that Bertrand had recognized him as an imposter but wanted to help him. Villagers described them as much happier together than she'd been with the previous actual Martin. Bertrand explained herself to the court by saying that she, being a simple woman, was deceived. The court, not wanting to rule illegitimate the children she'd had with Arnaud, accepted that plea and declined to charge her as well with adultery.

I wonder how 2XC would explain this one?
