This British crime cop show will appeal to fans of Cinemax "Quarry" or HBO "Boardwalk Empire" or HBO "True Detective" fans, but closer to "Quarry" in mood and "True Detective" in style. Don't be fooled by "PBS" logo, because show has swear words, naked corpse, vomit, and blood. Good mystery story, but show had only one story that had multiple subplots. High price for 6 episodes, but "Quarry" fans paid high price for low number of episodes. Beautiful lead actress highlights all-white cast. Recommended for gritty crime show fans ONLY that don't mind low number of episodes.
