-->''"Dangerous" because he's not, and "[[TitleDrop The Last Detective]]" because he's the last detective they'd send on a case.''

British mystery series starring Creator/PeterDavison as [[UsefulNotes/BritishCoppers Detective Constable (DC)]] "Dangerous" Davies; based upon the novels and characters of Leslie Thomas. Davies is a gentle, somewhat old-fashioned officer who clashes with his JerkAss colleagues, and is a rare example of a ButtMonkey protagonist, facing a separation with his wife and various incidents of ill-luck along with his colleagues' taunting. Despite this, he is a clever detective and always solves the case, often aided by his genius slacker friend Mod.

There had previously been a MadeForTVMovie called ''Dangerous Davies, the Last Detective'' starring Bernard Cribbins.

!!Contains examples of:
* ActorAllusion: Greta the German manager from "Lofty" is probably more familiar as Grete Grotowska, the girlfriend of Stephen Daker (Davison) in ''Series/AVeryPeculiarPractice''.
* ButtMonkey: Dangerous
* CowboyCop: Dangerous' [[UsefulNotes/BritishCoppers DI]] is a washed-up, alcoholic [[Series/LifeOnMars2006 Gene Hunt]] type who misses the good old days of honorable {{London Gangster}}s and PoliceBrutality. He's also an interesting version of NobleBigotWithABadge though, as he's actually ''less'' prejudiced than Dangerous' fellow officers who are modern police and often defends Dangerous from their taunting.
* DeathbringerTheAdorable: Dangerous is called that "because he's not".
* DeadPersonImpersonation: The episode "Lofty".
* DefectiveDetective: Dangerous' willingness to go after police corruption when he finds it leads to him being seen as one of these.
* DirtyCop: Any officer considered a mentor or friend by Dangerous' DI will turn out to be one of these.
* EmbarrassingFirstName: Mod is short for Modesty (after Tchaikovsky's brother).
* EnhanceButton: Used somewhat realistically in the episode with a SnuffFilm.
* EurekaMoment: Dangerous has one at least once per episode, generally during conversation with Mod.
* GagPenis: One episode has Mod's current girlfriend inform Dangerous' wife that Mod is rather well-endowed.
* GoodCopBadCop: With Dangerous as the good cop and the other officers as the bad ones.
* GeniusDitz: Mod is extremely well-read, but lacking in practical social skills.
* IdenticalStranger: One episode has Dangerous investingating some gangsters, aided by an informant who looks a lot like Mod. Mod ends up getting badly beaten by the gangsters, who mistake him for the informant.
* IronicNickname: Take a wild guess.
* KavorkaMan: Mod frequently manages to hook up with gorgeous women (sometimes shown on camera, sometimes not) despite being an utter slacker.
* TheLastDJ: Dangerous himself.
* LondonTown: Set in unpicturesque Willesden.
* MaleGaze: The episode "Christine" has Davies and DI Aspinall interviewing a financial advisor with a very short skirt. Several shots were from behind her legs and showed (as well as the aforementioned limbs) the DC and DI with suspiciously rigid expressions.
** The same episode presents a gender-flipped version in which Mod's legs get an airing. Viewers may differ as to the results.
* MotiveRant: Averted as generally the criminals (generally murderers) will have understandable reasons for their crimes and accept arrest with calm resignation.
* MurderDotCom
* NoNameGiven: Dangerous' real first name is never revealed. His ''dog'''s name is never revealed, either.
* OnlyKnownByTheirNickname
* OvertookTheSeries
* PluckyComicRelief: Mod
* RealLifeRelative: Creator/GeorgiaMoffett, star Creator/PeterDavison's daughter, had a guest role in the Series 4 episode "Once Upon A Time In The Westway". The producers wanted [[{{Squick}} her character to flirt with his]], but one or both of them (wisely) refused.
* SnuffFilm
* StalkerWithACrush: The title character of the episode "Tricia" who almost messes up Dangerous' life as badly as she had that of several previous men.
* TarotTroubles: At the beginning of the episode "Dangerous and the Lonely Hearts". As is common for this trope, Dangerous' card isn't as bad an omen as the script seems to think: he gets the Hanged Man, associated with (among other things) transformation and hard-earned wisdom.
* ThoseTwoGuys: DS Pimlott and DC Barrett, Dangerous' rivals on the force. They're not nice guys.
* {{Yandere}}: The eponymous character in "Tricia" is also one of these.
* YouDoNotHaveToSayAnything: In the first episode, Dangerous starts saying this after chasing down a perp, but is so winded the perp completes the reading for him.
