* AbilityOverAppearance: Creator/SharonSmall was supposedly too pretty to play the plain Barbara Havers, but absolutely nailed the character in the pilot and won author Elizabeth George completely over. Her performance is to this day lauded as one of the best aspects of the series.
* FakeBrit: The very Scottish Sharon Small as the very working-class ''English'' Barbara Havers.
* GermansLoveDavidHasselhoff: Like most British detective drama, this show is incredibly popular in Denmark. This is unsurprising, as British series have always been popular in Denmark and vice versa (for instance, ''[[Series/{{Forbrydelsen}} The Killing]]'' and ''Borgen'').
* {{Irony}}: One of Nathaniel Parker's earliest TV roles was in the first season of ''Poirot'' (the ep is "The Affair at the Victory Ball", if you want a look) [[spoiler: He's the killer.]]
* LikeBrotherAndSister: Creator/NathanielParker has [[http://www.pbs.org/wgbh/masterpiece/lynley/parker.html outright said]] that he sees Creator/SharonSmall as his little sister. Which did not, in fact, stop him from [[ShipperOnDeck shipping]] [[FanPreferredCouple Lynley/Havers]] like it was going out of style - or trying to kiss her (as Lynley kissing Havers)!
* TheOtherDarrin: Lynley's wife Helen was played by three separate actresses: Emma Fielding in the pilot, Lesley Vickerage in series one through three (up until she separated from Lynley), and Catherine Russell in series five.
* RealitySubtext: Interestingly, Parker's and Small's real-life backgrounds mirror those of their characters. Parker is the son of a UsefulNotes/{{knight|Fever}} (and former British Rail chairman), and, like Lynley, was educated at public schools ([[SeparatedByACommonLanguage private, for you Leftpondians]]). Small, on the other hand, is the daughter of a working-class single mother, grew up in the Glasgow tenements and attended the local [[TheGoodOldBritishComp comprehensive school]]. Parker says that when Small came to visit him at the beginning of their time working together, she took one look at his house and immediately turned into Havers! (By the time Sharon finished drama school in 1989, Parker had already had his big break in ''Pieces of Cake''.)
%% * ScrewedByTheNetwork: In this case, the network was the BBC.
* StarMakingRole: For Creator/SharonSmall, who proved herself a viable leading lady with this series.
* WhatCouldHaveBeen: Creator/NathanielParker said that he would have ended the series with Lynley and Havers [[ShipperOnDeck holding hands and walking into the sunset]]. Cue 90% of fans wishing passionately that Parker had been in charge of the show.
