MURDER MYSTERY

Shetland, 9pm, BBC1

IT’S the penultimate episode, and Perez is determined to find the truth. Andrea is standing in the way of that, and the detective’s frustration with her is palpable. Later, a connection in the case emerges between a house and Duncan (a subtle Mark Bonnar, pictured), who also claims to know nothing. Is he being honest, or is this just another person standing in Perez’s way?
