''The Fixer'' is an Creator/{{ITV}} drama that ran from 2008 to 2009.

Andrew Buchan plays John Mercer, an ex-soldier serving life for murdering his aunt and uncle after they molested his sister. One day, ex-cop Lenny Douglas visits him and offers him a release from prison...

If he becomes a [[JudgeJuryAndExecutioner government-controlled assassin who bumps off people the law can't bring to justice]].

So he does, aided by small-time crook Calum -- an annoying but loveable sidekick -- and Rose, a former policewoman [[spoiler:and Lenny's ex-wife]].

This is not related to TheFixer trope, or to novel ''Literature/TheFixer''.

----
!!This show contains examples of:

* AndYourLittleDogToo: Mercer refuses to live with Calum as he found him annoying as a cellmate, so Lenny has Calum garroted until Mercer relents.
* AntiHero: Calum's a Type I occasionally wandering into Type II, Mercer and Rose are Type [=IIIs=], and Lenny's a Type IV frequently straddling Type V.
* BlackAndGrayMorality: Mercer's hits are about protecting the Establishment and keeping British society stable, rather than punishing evildoers.
* BumblingSidekick: Calum
* CliffHanger: [[spoiler:The ending of the second season.]]
* GoodIsNotNice: Hot-tempered, coldly regimental Lenny all the way. Mercer, too, for the most part, though he has more PetTheDog moments, mostly with Calum and his sister.
* HoneyTrap: Rose Chamberlain was thrown out of the police for trying this tactic to snare a rapist, which was deemed "entrapment". She continues to do so however to gather information for the unit, [[MyGirlIsNotASlut much to Mercer's distaste]].
* LatinLover: Manuela
* MoralityPet: Mercer's sister.
* PluckyComicRelief: Calum
* ProfessionalKiller
* RogueAgent: In one episode Mercer is ordered to kill his predecessor, who has started to [[VigilanteMan pick his own targets]] instead of those selected by Lenny. On another occasion an SAS man who (under orders) used drug money to finance his anti-Taliban operation decided to go into business for himself.
* {{UST}}: Between Rose and Mercer. Calum often lampshades this.
