* TheReasonYouSuckSpeech: Adrian Mullery gives DC Jake Collier an absolutely blistering one in Series 3, [[spoiler:having spent eighteen years trying to live down being the prime suspect in the case and full of absolute rage at the police’s utter incompetence and botching of the initial investigation. A full transcript can be found on the quotes tab.]]

** Series 4 has one that verges on an outright DownerEnding.[[spoiler:Dean]] admits to having killed Matthew Walsh in a fit of rage as Matthew [[spoiler:killed Dean's brother months previously]], and his [[spoiler:cocaine smuggling network which Ram was involved in is exposed]]. The other three all are arrested for helping to dispose of the body but Fiona's husband promises to stay with her and Liz resolves to live a better life and gives her mother's financially struggling houskeeper a check for £10,000.

* RedHerring: Every episode, naturally, but some egregious ones include Marion's links to the IRA in Series 2, Elliott's car accident and ''all'' of Pete's exploits in Season 3.

* ShippingBedDeath: Although not sex. You can't really blame people for shipping Sunny and Cassie, two dysfunctional and lonely detectives, but Cassie awkwardly kissing Sunny (and being shut down) at the end of Series 2 more or less torpedoes it.

** Season 4: [[spoiler:Cassie's dad]] NeverGotAChanceToSayGoodbye because they were fighting, and he chose to ignore the phone message she left when she said she wanted to apologize, [[spoiler:before she died in a car accident.]]

* {{Retirony}}: After being forced to return to the police force for 3 months in order to be eligible for her pension, all Cass wanted to do was finish her last case and retire to a new life with her partner, John.
