* [[spoiler:ADeadlyAffair]]: The motive for some of the murders in series 1.

* ConMan: Series 3 starts with Pete persuading an elderly man to part with £3,000, supposedly for a house, but instead spends it on his family. To be fair, Pete does give it back when asked, and pretends it was a mistake. He doesn't fool anyone.

* ElderAbuse: [[spoiler:Matt]] and gets away with it too.

* NeverOneMurder: A new body turns up at [[spoiler:the Slater's]] house.

* MakeItLookLikeAnAccident: a potential witness is killed off screen. His house was set on fire and it was made to look like he fell asleep with a lit cigarette. No one would have known if the person who ordered the hit hadn't confessed.

* DisposingOfABody: Done surprisingly well in series 1. The skeleton when it was found 40 years after burial was thought to be possibly hundreds or thousands of years old. Were it not for a very persistent DCI, and [[AppliedPhlebotinum an extremely good lab]], the police would have written it off as such.

* BeAsUnhelpfulAsPossible: To the point where anyone who is ''being'' helpful is instantly suspicious. Overlapping with...

** [[Spoiler: Claire's]] husband had numerous extra marital affairs. But after she had children and untreated post partum psychosis, instead of talking to him about it she simply murdered the people he was having affairs with.
** Josh gives [[Spoiler: Frankie]] contact with some shady people. Instead of just using the shady people to threaten potential witnesses into silence, he has one murdered.

* DisposingOfABody: Done surprisingly well in series 1. Were it not for a very persistent Cassie, and an extremely good lab, the skeleton when it was found was thought to be possibly hundreds or thousands of years old.

* RevisitingTheColdCase: The basic premise of the series. The show stresses how unsolved murders are as worthy of investigation and punishment as new cases, and the families of the victims continue to feel great pain.

** Series 2 had [[spoiler:Marion Kelsey, Colin Osborne and Sara Mahmoud]]. The [[spoiler: three]] were motivated by revenge and worked together to kill each other's abusers thus giving each other perfect alibis. They were all distraught and broken by [[RapeAsBackstory their experiences as children,]]
** Series 3 had [[spoiler:Tim Finch]]. Whilst series 2 has a killer who was a victim and sought revenge and series 1 had a killer who was similarly motivated [[spoiler:Finch]] did what he did simply ForTheEvulz. In addition, [[spoiler:he]] is well-respected, affluent, and outwardly respectable.

* DeliberateValuesDissonance: Given the main characters investigate cold cases, a lot of the attitudes are reflective of the times meaning many characters express racist and homophobic attitudes generally considered unacceptable by today's standards.

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

* TheSociopath: [[spoiler:Tim Finch]] describes [[spoiler:himself]] as a "textbook psychopath" in Series 3.
* StrangersOnATrainPlotMurder: [[spoiler:Series 2 towards people who have been in psychiatric care for the trauma of child sexual abuse.]]

* WithFriendsLikeThese: Series 3 deliberately deconstructs this.

* BewareTheNiceOnes: Tessa in Series 2 and [[spoiler:Finch]] in Series 1 are two notable examples.

* WhamLine: In a series full of them one from the series 3 finale really sticks out:

* WhoMurderedTheAsshole: All over series 2.

* TooGoodForThisSinfulEarth: Notably subverted by David Walker, who is a CompleteMonster, but played straight by Hayley Reid and HookerWithAHeartOfGold Jimmy.
