[[http://www.fanfiction.net/s/7970217/1/A_Study_In_Regret ''A Study in Regret'']], by [[http://www.fanfiction.net/u/3677015/Riandra Riandra]], is an [[AlternateUniverse AU]] to the events of the Literature/SherlockHolmes short story "The Final Problem". The [[http://www.fanfiction.net FF.N]] summary is as follows: ''Dedicated to [[http://www.fanfiction.net/u/1758544/Aleine_Skyfire Aleine Skyfire]]. What if events had turned out for the worst after Moriarty's death at Reichenbach? Character death, drug and torture references.''

When the fic opens, Colonel Sebastian Moran has already [[HeroKiller murdered]] [[TheWatson Dr. Watson]] at the Reichenbach Falls. Literature/SherlockHolmes is now Moran's prisoner, and is being constantly "punished" for the death of Professor Moriarty. Not all hope is lost, however, for InspectorLestrade and Mary Watson are on the case, and they're determined not to fail.

The story has now expanded into a duology, with the first part completed. The working titles for the two novels are ''Children of Reichenbach: A Study in Regret'' and ''Children of Reichenbach: The Final Solution''.

Now has a [[Characters/AStudyInRegret character sheet]] under construction.

----
!! This fanfic provides examples of:

* ActionGirl: Mary Watson, [[HiddenDepths of all people!]]
* AscendedExtra: Moran to BigBad, Lestrade to {{Deuteragonist}}, and Mary to supporting female. [[TeamMom Literally.]]
* AuthorityEqualsAsskicking: In the [[Literature/SherlockHolmes canon]], [[BigBad Moriarty]] hired [[TheDragon Moran]] for his skills. ''A Study in Regret'' makes it painfully clear what skills those were.
* AvengingTheVillain: The reason, basically, this entire story happens at all.
* BerserkButton: Moran ''knows'' Holmes's is Watson and banks on this.
* BigBad: Who needs ''Moriarty''? His [[TheDragon second-in-command]] is more than enough!
* BirthDeathJuxtaposition
* ChokeHolds: As part of Moran's VillainousBreakdown (see below), he starts to throttle Holmes.
* ColdBloodedTorture: There's not even any real point to Holmes's torture, other than AvengingTheVillain and ''possibly'' BreakTheHaughty.
* CurbStompBattle: Watson and Holmes never stood a chance against Moran and his {{Mook}}.
* DarkerAndEdgier: [[SarcasmMode In case you didn't get that,]] already.
* DeathFic: Since Watson's death plays a very big part in this story... yeah, this is definitely a DeathFic.
* {{Determinator}}: Lestrade and Mary.
* DistressedDude: Poor, poor Holmes...
* EmotionalTorque: There are a lot of Sherlockian [[DeathFic Death Fics]] out there and even more DarkerAndEdgier fics... but very few take their readers on as long and realistic a journey as ''A Study in Regret'' does. The entire story is one great emotional roller-coaster, and some ''individual'' chapters are self-contained roller-coasters in their own right.
* EvilGloating: Holmes asks if Moran would like to continue this, trying to stall him. It doesn't work.
* FlashbackNightmare: Used several times for poor Holmes.
* TheHeart: Mary, oh so much!
* {{Homage}}: Not only to the {{Canon}} but to the ''Fanfic/DeliverUsFromEvilSeries''.
* InspectorLestrade: Inverted, actually, as he gets his chance to really shine as TheHero.
* LikeBrotherAndSister: Lestrade and Mary.
** [[spoiler: And, gradually, Mary and Holmes - she just seems to have that effect on people.]]
* LockedInTheDungeon
* LoveHurts
* ManlyTears: It's not just Holmes, either - in fact, he once weeps because he sees ''[[NotSoStoic Lestrade]]'' weeping.
* [[BilingualBonus Multilingual Bonus]]: There's a ''lot'' of untranslated French and German in the flashbacks, plus ''translated'' French and German later on.
* MyGodWhatHaveIDone: Invoked by Holmes.
* NarrativeProfanityFilter: Used on occasion, and once with ''Mary''!
-->[[MomentOfAwesome Mary swiftly produces a revolver from somewhere,]] muttering something [[ForeignCussWord decidedly ungenteel in French]] where did she learn words like that?
* NotSoStoic: The author takes Holmes's infamous stoicism and hurls it out the window.
** Lestrade's emotions are fully realized, as well.
* OnlySaneMan[=/=]TeamDad: Dear Lestrade.
* RescueArc: Ingeniously done through flashbacks.
* RevengeByProxy: [[spoiler: Holmes realizes that this is how Moran means to get back at him - by killing Mary and her baby.]]
* TheSmurfettePrinciple: Very much in play here - however, with Mary Watson as an actual ''ActionGirl'', it's worth it!
* TeamMom: The attitudes of the men around Mary make it pretty clear who's in charge, here!
* TortureAlwaysWorks: Holmes is pretty far gone [[spoiler: when Lestrade & Co. rescue him]].
* ToThePain: Moran "introduces" his viper Naja to [[WhyDidItHaveToBeSnakes a terrified Holmes]].
* TrueCompanions: Lestrade, Mary, and Roland.
* UnwittingPawn: Poor, poor Roland.
* VillainousBreakdown: Moran ''almost'' does this [[spoiler: when Holmes kills his viper.]]
* VictorianBritain: Averted, making it one of the few period-Sherlockian fics to do so. And the author averts it.
* WhatTheHellHero: Mary delivers a downright cringe-worthy one to Holmes... ironically, berating him for even ''considering'' the ''exact'' same vanishing act he performed in the original stories.
* WithAFriendAndAStranger: Lestrade with Mary... and Roland.
