DNA confirms Duncan as Alan Killick's father and possibly a double killer and he is arrested. Then a perusal of Sally's files brings another suspect into the picture, literally - one who had good reason to dispose of Lizzie and who makes a confession of guilt. However Jimmy discovers that this person may not have murdered Sally but still finds both Duncan and himself in a dangerous situation before there is closure. Written by don @ minifie-1

Iconic season finale
24 July 2018 | by njhammersSee all my reviews

Shetland is so good not because of fancy plots or intricate stories, even though it has both, no it's the characters and the acting , the core group of DI Jimmy Perez DS Tosh , DC sandy , Cassie & Duncan are simply superb & especially the glorious lead, such a thoroughly good man , who combines intelligence, toughness with being actually a heroic man & father. This episode 6 was at the same tense, riveting , believable , even with multiple twists and turns, this left me breathless and panting for season 5 . By my book after Line of Duty the best British TV cop series & right up their in my pantheon of great tv series with breaking bad, Sopranos, Lost, Prime Suspect and the aforementioned Line of Duty. Mega kudos to all involved, simply magnificent
