This week on Annika, the Marine Homicide Unit is in a transition period. The police assign Harper from the Edinburgh investigation in Episode 2 to the unit as Tyrone has started his new job. (Unfortunately for fans of Ukweli Roach, his new show Wolf is not available in America yet.) Blair is now on office duty as her due date approaches. The rest of the team is sent to the islands of Jura and Islay in the Scottish Hebrides as there are no police stations there to investigate a murder victim found frozen in a block of ice. Annika still has to negotiate working with Michael while someone else from her past reappears to upset the balance of her life. Let’s find out how George Orwell’s writings tie into Annika’s emotions and the case.
