The new series of Line of Duty has kept viewers on the edge of their seats as AC-12 search for H.
Jed Mercurio's drama first hit screens in 2012 and it's proved to be a viewer favourite ever since.
Vicky McClure, Adrian Dunbar and Martin Compston returned for the sixth Line of Duty series with Shalom Brune-Franklin, a new addition to the AC-12 team.
Kelly Macdonald made her debut as guest lead Detective Chief Inspector Joanne Davidson, the senior investigating officer on an unsolved murder case whose suspicious conduct attracts the attention of Anti-Corruption.
The team recently discovered that DCI Davidson has strong ties to the OCG as she was outed as a relative of gang leader Tommy Hunter.
But this hasn't stopped her from running Operation Lighthouse and working with undercover gang member Ryan Pilkington.
The opening episode of series six was watched by 9.6 million viewers.
That surpassed the show's previous record of 9.1 million for the finale of series five in 2019.
