The "Small Change" trilogy by Creator/JoWalton -- consisting of ''Farthing'', ''Ha'penny'', and ''Half a Crown'' -- is a series of detective novels set in an AlternateHistory where World War II ended with Hitler still alive and in possession of most of continental Europe.

''Farthing'' starts out as a classic English country-house murder mystery, investigated by Inspector Carmichael of Scotland Yard, but becomes darker and more complicated as Carmichael begins tripping over the political threads that run through the case. Things go downhill from there, for Carmichael personally and for England as a whole.

The short story "Escape to Other Worlds With Science Fiction" is set in the United States in the same timeline, with different characters.

!!This series provides examples of:

* AllohistoricalAllusion / DifferentWorldDifferentMovies: An unnamed handsome singer from Liverpool at the British Power rally in ''Half a Crown'' is almost certainly PaulMcCartney. Several references are made to a science fiction novel titled ''[[Literature/NineteenEightyFour 1974]]''.
* AlternateHistory: The main departure point is the US not supplying the Allies through the Lend-Lease Act.
* TheAtoner: Carmichael, especially towards those who are KilledToUpholdTheMasquerade in ''Farthing'', and the driving force behind the Inner Watch.
* BigBrotherIsEmployingYou: Carmichael in the latter part of the series.
* BiTheWay: David Kahn was Lucy's brother's best friend and lover in the RAF- David is very reluctant to admit it, but Lucy completely understands. Lucy seems to have particularly good {{Gaydar}}, spotting those who are "Greek" (gay), "[[AlexanderTheGreat Macedonian]]" (bi), and "Roman" (straight).
* ABloodyMess: in ''Farthing''
* ConcertClimax: in ''Ha'penny''
* CrypticBackgroundReference: In ''Half a Crown'', it's never stated what happened to cause the large amount of unrest and crackdowns in 1955.
* DayOfTheJackboot: England in this timeline.
* [[spoiler: EverybodyDidIt]]: ''Farthing''
* EvilCripple: [[spoiler:Mark Normanby]] after the events of ''Ha'Penny''.
* FamilyThemeNaming: The Larkin sisters in ''Ha'penny'' are all named after Shakespeare characters.
* FlawExploitation: Carmichael has the threat of [[ArmoredClosetGay being exposed as gay]] and [[ShameIfSomethingHappened his partner Jack's safety]] constantly hanging over his head.
* GenteelInterbellumSetting: The series effectively extends this into the 1950s, with Britain only participating in WorldWarII from 1939-41.
* GreatOffScreenWar: Germany continued fighting on the Eastern Front past 1949; Japan conquered most of China.
* GreedyJew: Subverted in ''Farthing''. David Kahn is in fact a moneylender who specializes in helping the poor start small businesses.
* HitlerAteSugar: Events from ''Ha'Penny'' get a CallBack in ''Half a Crown'' with the fallacious saying going around amongst the debutantes: "[[spoiler:Viola Larkin]] asked a man to dance with her at a ball, and look where ''she'' ended up!"
* {{Homage}}: David and Lucy Kahn's story owes quite a bit to ''BridesheadRevisited'', albeit with a happier ending for their relationship- up until the events of ''Farthing'', that is.
* HonoraryUncle: Carmichael to Elvira in ''Half a Crown''
* INeverSaidItWasPoison: in ''Farthing''.
* KilledToUpholdTheMasquerade: [[spoiler:Alan Brown, Agnes Timms, and Lady Thirke]] in ''Farthing''.
* MyGodWhatHaveIDone: in ''Ha'penny''
* NaziNobleman- Several appear among the Farthing Set and the Larkin family (especially as they are based on the Mitfords). The British Power movement in ''Half a Crown'' is not quite the Hitler Youth, but they come close.
* NiceJobBreakingItHero: Being a generally good person and a good policeman, Carmichael saves some people in ''Ha'Penny''. Unfortunately he saves [[spoiler: Hitler and fascist Prime Minister Normanby]]. He soon realizes things would have been better off if he hadn't done anything.
* NoCelebritiesWereHarmed: the eccentric upper-class Larkin sisters central to ''Ha'Penny'' are clearly based on the real [[http://en.wikipedia.org/wiki/Mitford_family Mitford sisters]], right down to some becoming fascists and one becoming a communist. Unity Mitford is mentioned in ''Half a Crown'', so they still exist.
** Guy Braithwaite is a Soviet sleeper agent, who is so well-intrenched in fascist British politics he's become Foreign Secretary by the events of Half a Crown in 1960. He is modeled on [[http://en.wikipedia.org/wiki/Guy_Burgess Guy Burgess]] and [[http://en.wikipedia.org/wiki/Donald_Maclean_%28spy%29 Donald Maclean]], real-life British Soviet spies in the Foreign Office. After the USSR was defeated by the Axis, Braithwaite remarks that maybe Stalin wasn't the answer any more than Hitler was, and [[spoiler: he winds up Prime Minister after Normanby is arrested for James Thirkie's murder.]]
* NoodleIncident: Royston refers to "that man with the stockings" as one of their old cases. He's never mentioned again.
* AnOfferYouCantRefuse: Carmichael is blackmailed into [[spoiler:effectively becoming leader of a [[StateSec British gestapo]]]].
* RageWithinTheMachine: Carmichael, Jacobson, and the rest of the "Inner Watch", who secretly use the power and resources of their StateSec jobs to operate an extensive underground railroad.
* RichBitch: Most of the women in the Farthing Set
* SettledForGay: Poor Daphne Normanby.
* ShoutOutThemeNaming: The Larkin sisters, all named after Shakespeare characters.
* StageName: ''Ha'Penny'' has Viola Larkin, who goes by Viola Lark on the stage to distance herself from her famous and influential BlueBlood family.
* StateSec: The Watch in ''Half a Crown''.
* SuicidePill: In ''Half a Crown'', everyone who's aware of the "Inner Watch" is fitted with a poison tooth as a matter of course. [[spoiler:Jack opts to use his when he is brought in by the police.]] [[spoiler:Carmichael's]] tooth is forcibly removed before he can get a chance to break it.
* TenLittleMurderVictims: subverted in ''Farthing'', which is set up as a classic country house GenteelInterbellumSetting murder mystery, then turns out to be [[spoiler:[[EverybodyDidIt a political conspiracy]]]].
* TokenEnemyMinority: {{Invoked}} by Jacobson in ''Half a Crown'', the token Jewish member of the Watch. He's [[ZeroApprovalGambit perceived as]] a [[TheQuisling Collaborator Figurehead]] by most of the remaining British Jewish community, who naturally don't know he's part of the Inner Watch's RageWithinTheMachine.
* TwoLinesNoWaiting: Each of the novels is structured with alternating chapters from the point of view of Inspector Carmichael (3rd person), and a young woman writing in the 1st person: Lucy Kahn in ''Farthing'', Viola Larkin in ''Ha'Penny'', and Elvira Royston in ''Half a Crown''.
* UndergroundRailroad: The Inner Watch
* WellIntentionedExtremist: The Scottites and their IRA connections in ''Ha'Penny''.
* WhereEverybodyKnowsYourFlame: The Caravan Club in ''Half a Crown.''
* ZeroApprovalGambit: Throughout the books, Carmichael is attempting to [[TheAtoner make up for the moral compromises]] he has been blackmailed into by getting as many innocents as he can [[UndergroundRailroad out of the country]].
