Curiosity Caught the Kat - S8-E3
Factual error: (Spoiler alert) At the end of the episode DCI Wainwright arrests DI Fisk on a charge of "corruption." As a senior police officer she would know there is no such charge, and the word "corruption" is far too general a term to be used as a criminal charge anyway. Fisk would be charged with "Misconduct in public office contrary to section 1 (1) of the Criminal Law Act 1977."
