Line of Duty series 2 finale review: What were the final twists?

Who killed Danny Latimer? - Broadchurch



The question of who offed poor Danny in the seaside town of Broadchurch was on the lips of most of the British public back in early 2013. The same mystery later had US viewers hooked when the eight-parter aired on BBC America at the tail-end of the year - so much so that Fox later commissioned its own version of this particular whodunit.

Who killed Nanna Birk Larsen? - The Killing



Nordic noir is now such a big deal that aficionados attend the genre's own special conventions sporting Sarah Lund-inspired knitwear - and the whole thing kicked off with this brilliant 20-episode whodunit, which slowly unravelled the murky circumstances surrounding the murder of 19-year-old Nanna Birk Larsen. Whether you watched week-by-week on BBC Four or devoured the whole thing on DVD, The Killing was never less than utterly gripping.

Who killed Laura Palmer? - Twin Peaks



The killing of Sheryl Lee's homecoming queen Laura Palmer was the catalyst for David Lynch's brilliant, surreal creepfest Twin Peaks. Easily one of television's most genuinely unsettling murder mysteries, this whodunit came to a diabolically dark conclusion involving incest, rape and demonic possession.

Who shot Mr Burns? - The Simpsons



Yes, it does so count. Alright, so it was designed as a spoof of the whole TV whodunit trope, but 'Who Shot Mr Burns?' accidentally became properly compelling. Everyone in Springfield - from Homer to Smithers - had a reason to try and off devious old Montgomery and 16m viewers across the US ultimately tuned in on September 17, 1995 to learn who pulled the trigger.

Who killed Lilly Kane? - Veronica Mars



The first season of recently-revived cult favourite Veronica Mars had this very personal mystery at its heart. Spanning 22 episodes, the investigative efforts of teen 'tec Veronica (Kristen Bell) ultimately helped to uncover the sordid truth surrounding her best friend's murder.
