During the eighties and early nineties, the world of [[AdventureGame Adventure Games]] belonged to {{Sierra}}. Games series like ''VideoGame/KingsQuest'', ''VideoGame/SpaceQuest'', ''VideoGame/PoliceQuest'', and ''VideoGame/QuestForGlory'', established the company's love of quests, and in 1989 there was ''Laura Bow: The Colonel's Bequest'', following in the same naming format of putting the word "quest" somewhere in the title of each game. The game was created by Roberta Williams of ''King's Quest'' fame, and borrowed elements from Williams' ''Mystery House'', created in 1980 and known as one of the first graphical adventures.

''The Colonel's Bequest'' used a traditional text parser and 16 color graphics, much like Sierra's other games of the time. The plot, which took place in 1925, involved protagonist Laura Bow, a graduate of Tulane University, being invited by her friend Lillian to her uncle's New Orleans plantation home, where relatives and employees have gathered for the reading of the old Colonel's will. Secrets and deceptions abound as the guests quickly start to disappear, and it is up to Laura to find out what is going on and solve the mystery before it is too late. [[BrokenAesop Turns out she can't]]: almost everybody will die regardless of what you do, and none of the secrets and deceptions are at all related to the murderer.

Unlike most of Sierra's adventures, the game stood out in that it focused on gathering information and evidence by asking questions or overhearing conversations rather than the typical formula of putting two items together to achieve a goal, although there were a few item-based puzzles to solve that would help Laura obtain additional clues. The player was required to figure out for themselves what was going on by piecing together parts of the story. In the end of the game, you find two fighting people and get to shoot either of them, and will receive a "good" ending or a "bad" ending depending on which you pick. There were also many clues that did not have to be uncovered in order to win the game, increasing replayability and challenging the player to become an amateur sleuth.

Another thing that made the game notable was that it ran on a time system that would change when Laura triggered an event every fifteen minutes, the entire game taking place over the course of one night. Because the game didn't tell you outright what you were supposed to do with the information you collected, it is difficult to know just what is going on on the first playthrough, and easy to miss important events if you triggered the next event too soon. Characters would make plans to meet in various places at certain times and could be followed or spied upon.

The second and last in the series, ''The Dagger of Amon Ra'' (1992), used 8 bit colors and a point-and-click interface. It takes place a year after the first game, in New York, where Laura, now a newspaper reporter, is charged to write a story about the dissapearance of an antique dagger from a local museum. Attending a benefit at the museum, she meets the various suspects, who quickly begin to die off one by one. This game had a similar time system but involved more straight-forward, item-based puzzles than the previous game. Like its predecessor, it also required the player to make their own conclusions in order to solve the murders. The identity of the murderer is not revealed at the end of the game, and instead the player is asked a series of questions in order to determine who the culprit is based on evidence collected.

!!The Series Provides Examples Of:

* AcquittedTooLate
* AmateurSleuth
* AlwaysMurder
* AssholeVictim
* BigApplesauce: ''Dagger of Amon Ra''
* BigSecret: Almost everyone has one.
* BigScrewedUpFamily: In the first game.
* BookEnds: The BadEnding of ''The Dagger of Amon Rah'' mimicks the opening except with the layout of the room mirrored [[spoiler: and Laura getting shot instead of strangled]].
* BookcasePassage
* CassandraTruth: No one ''ever'' believes Laura when she warns them about the murders. In the first game, [[spoiler:half of the estate's inhabitants have been killed before anyone believes that something's happening]].
* CurtainCamouflage
* DarknessEqualsDeath: don't go down that dark staircase without a light!
** If Laura goes through any of the secret passageway tunnels in the sequel without either lighting the lamp before she enters or while inside, she will be attacked by bats, which is odd when [[FridgeLogic these tunnels have no critter or any other danger whatsoever when lit]]. Subverted in the last tunnels near the end of the game as while you don't immediately get killed for entering in the dark, you can't do anything productive without lighting your lamp and you can still get killed.
* DeadMansChest
* DeadPersonImpersonation: [[spoiler: Dr. Archibald Carrington]] in the second game.
* DirtyOldMan: Doctor Wilbur B. [[PunnyName Feels]] of the first game.
* DramatisPersonae: The first game is presented as if it is a stage play, introducing the cast this way before the start of act one.
* DropInNemesis: various things Laura did could cause the murderer to appear out of nowhere in the first game, including taking a shower, in an homage to ''Film/{{Psycho}}'', complete with a snarky HaveANiceDeath.
* DysfunctionJunction
* EvidenceScavengerHunt
* EveryoneIsASuspect
* EveryoneLooksSexierIfFrench: Both [[TheVamp French people]] are ''massive'' flirts, and the first one is actually a FrenchMaid, ... ooh la la..
* EverythingTryingToKillYou: in true Sierra fashion, Laura will die unexpectedly if she so much as takes a wrong step, often from accidental murder rather than by the actual killer.
* ExactEavesDropping: Both games.
* {{Expy}}: The first game is a DarkerAndEdgier adaptation of the popular tabletop game ''{{TabletopGame/Clue}}'' - turned into a narrative story as seen from the eyes of the detective. Though many liberties were taken in order to make it as engrossing as it is, most of the setting and characters are based directly on the tabletop game. Most notable are the characters of Colonel [[IncrediblyLamePun Dijon]] (Mustard) and Ethel Prune (Plum), the many secret passageways throughout the mansion, and the various weapons used by the murderer during the game (poison, pistol, dagger, and so on).
* FallingChandelierOfDoom: one of the ways Laura could die in the first game
* FunnyTerrainCrossSection: [[spoiler: In the first game, the underground passage to the mansion's secret basement contains a tyrannosaurus skeleton.]]
* GenteelInterbellumSetting
* GuideDangIt: even more than a typical Sierra game, considering many of the actions required to get the best ending don't make sense.
* HaveANiceDeath: The shower scene mentioned above gives you the death message "didn't [[Creator/AlfredHitchcock Alfred]] teach you anything?"
* HeroesWantRedheads: Both the heroine and her love interest in the second game are redheads.
** [[spoiler:The villain of the second game is also a redhead.]]
* HiddenInPlainSight: After the Dagger is stolen in the second game, the thief tries to stash it among the replicas in the gift shop.
* HiddenVillain: [[spoiler:Lillian]], who you do not find out as the murderer unless you search very hard.
* {{Homage}}: the aforementioned shower scene.
* IntrepidReporter: Laura in the second game.
* ItsAWonderfulFailure
* ItWasHereISwear: In the first game, every time Laura comes across a dead body or the signs of a struggle, everything is immaculately cleaned up moments after she leaves, making it hard to tell anyone what's going on.
* TheJeeves: Lampshaded with the butler ''named'' Jeeves!
* TheKillerBecomesTheKilled: In both games:
** [[spoiler: Lillian had done all the murders in the first game, yet was found dead in the garden. As it turns out, she had intended to kill Rudy, but Rudy had fought back and killed her in self defense.]]
** [[spoiler: Watney Little had killed Carrington in the second game but was then killed by O'Riley.]]
* LadyDrunk: Ethel Prune in the first game
* LookBothWays: in the second game, you need to look both ways in order to cross the street safely.
* MoonLogicPuzzle: Often the information is there, the game just doesn't tell you what it means.
* MorallyAmbiguousDoctorate: Dr. Feels
* MultipleEndings: In the first game, you either [[spoiler:shoot the colonel, or do nothing and let Rudy kill him in the struggle, which is the bad ending]] or [[spoiler:shoot Rudy and injure him, resulting in the good ending.]] In the second game, it's get all the accusations wrong.
* NastyParty: In the bad ending of the first game [[spoiler: Rudy lies that this was the Colonel's plan all along.]]
* NeverOneMurder
* NightmareFetishist: Olympia Myklos in the second game. Her boyfriend, Wolf Heimlich, shares some of her morbid interests as well.

* TheOphelia: [[spoiler: Lillian]] in the first game.
* PassedOverInheritance: Given the fact that the Colonel stated that his estate will be divided equally among everyone present at the manor when he made the announcement who outlives him (Other than Laura), the obvious explanation as to why virtually everyone in the manor turns up dead over the course of the next few hours is that the killer is someone hoping to increase their share of the pie. [[spoiler: It's actually Lillian, who doesn't care about the money but wants to restore her perceived status as the Colonel's favorite relative by making her his ''only'' relative.]]
* PeekABooCorpse
* PerfectPoison: in the first game, sleeping powder is used, and mixed with Alcohol.
* PluckyGirl: Laura, of course.
* ProtagonistCenteredMorality: In a minor example, Celie is the only person you can befriend in the first game. [[spoiler:She ends up being the sole surviving heir to the Colonel's fortune]].

* WingedSoulFliesOffAtDeath: A couple of deaths in the first game.
* WhoDunnit
* YetAnotherStupidDeath: The chandelier only falls on you [[spoiler:if you walk down the exact center of the first floor hallway. Which is right where the front doors deposit you, causing plenty of accidental deaths when the player forgets to sidestep]].
