In Season $4$ of the popular TV series "Downton Abbey," a card sharp named Sampson steals a letter written from Prince Edward of Wales to Freda Dudley Ward, purportedly to blackmail the prince. Our heroes seek to return the letter by taking it from Sampson. When questioned about the plan, Lord Grantham says, "you can't steal something that's already been stolen" $($Ep$.409,44$:$16).$ Which of the following explanations is correct, according to Law $101?$

A$.)$ Lord Grantham is right: the only person who has any claim to the letter is the original owner.

B$.)$ Possession is nine$-$tenths of the law: as soon as Lord Grantham and his family are in possession of the letter, it becomes their property.

C$.)$ Lord Grantham is wrong, because while Sampson doesn't own the letter, he has a superior right of ownership to someone trying to steal it from him, no matter their intentions.

D$.)$ Property is a relationship between people and things: Mrs$.$ Dudley Ward owns the letter, and so taking it from Sampson is not wrong at all.
