On Duty

With credits including medical dramas Cardiac Arrest, Bodies and Critical, Jed Mercurio is best known for his thrilling police drama Line of Duty.

As the series returns for a fourth season on BBC1, Mercurio tells DQ why the show isn’t a typical police drama, why he prefers to be its sole writer and how he constructs its trademark interrogation scenes.

He also reveals how his role as a showrunner grew from a feeling that writers were marginalised from the rest of the creative process.
