What BollyAI Thinks

Series 3 moved to BBC One and landed another perfect critical score on Rotten Tomatoes. The series introduced a wider criminal conspiracy within the police, centered on "the fourth man" and an organized crime group (OCG), building mythology that carried across the remaining series. Vicky McClure's DS Kate Fleming was now a full co-lead alongside Compston, with the show developing a genuine repertory ensemble. The jump to BBC One also scaled up its reach, reinforcing its status as a prestige flagship drama in British television.
