Starring: Andrew Neil McKenzie, Victoria Pedretti
The Two Faces, Part One - S1-E3
Factual error: The British policeman carries an American-style long baton on his belt. No British police force used batons before 1994 (the series is set in 1987), and batons of this pattern were never used in any case.
Factual error: Dominic Wingrave says "it took me 6 years to do the math." Not something any British person would say - in the UK it's always "maths."
Trivia: The character of Dani Clayton is named after Jack Clayton, who directed "The Innocents." "The Innocents" is the film adaptation of the stage version of Henry James' "The Turn of the Screw." (Source: ScreenRant).
