I am sure that you should remark on the (blindingly) obvious fact that according to all laws and traditions, Musgrave was totally in the wrong, committing 'fornication' at the minimum, and Lord Barnard had 'right' on his side, killing in a crime of passion, after finding his wife not only in bed with another man, but a commoner at that.

And yet Musgrave is always the hero, all our sympathies are with him, Lord Barnard is painted as a cruel and wicked man, and his faithful servant as a vile spy!

This is surely a remarkable feat of storytelling.
