Line of Duty returns this Sunday 26 March at 9pm on BBC One.
With each new series, Line of Duty has raised the stakes so dramatically it’s a wonder how you’ll make it through another episode; you’ll manage – Mercurio has crafted a series that belies the lax attitude paid the way of British TV due to the onset of iPlayer and Netflix.
Line of Duty is that rarity – a show watched by the masses without ever preaching to them.
This series deserves to be viewed with lights dimmed, phone off and your attention focused squarely on the TV in front of you.
