Reminds me of Sherlock Holmes with Benedict Cumberbatch in an episode where the villain (spoiler alert) is a mega wealthy philanthropist who is majority owner of a hospital so he can have access to people to kill at his leisure.
Series 4 Episode 2

A lot of those episodes seem to give glimpses into what happens, like mkultra, newspaper owners blackmailing politicians, etc.
Cumberbatch also played Dr. Strange
