In what is stone cold guaranteed to be an unmissable final episode of the current run of Line of Duty things come to a head with AC-12 and Roz as well as finding just who the Balaclava man really is. Is it really Roz’s husband Nick or will writer Jed Mercurio throw one of his infamous curve balls at us.
This series has totally belonged to Thandie Newton as the stop at nothing Roz Huntley. She may now be “fairly armless” but she will still be very dangerous.
Line of Duty Season 4 Episode 6 airs on Sunday 30 April 2017 at 9.00pm on BBC One.
