True Detective, Sky Atlantic, 9.00pm

Almost 20 years on from their first meeting, and more than ten since they fought in the police department car park and went their separate ways, Rust and Marty are back together. Rust has spent the past two years piecing together fragments of a sprawling conspiracy that he’s sure condemns the powerful Tuttle family as the guilty centre of an horrific web of abuse, deceit and murder. After persuading Marty that he owes a debt to Dora Lange, Rust takes his old partner to a lock-up and shows him the fruits of his private investigation – maps, research, horrific pictures, a sickening video – it’s enough to convince Marty that there’s a case for someone to answer.
