From the article:
Since the mid-sixteenth century Rich has had a highly negative reputation for immorality, financial dishonesty, double dealing, perjury and treachery that is seldom matched in all of English history. The historian Hugh Trevor-Roper dismissed Rich as a man “of whom nobody has ever spoken a good word”.
As a side note, in Wolf Hall, Rich is played by Bryan Dick. So Bryan is playing my great-great-something grandpa. :p
Hmmm, it's been a while since I used the Bryan as Blythe icon.
