History Main / SummationGathering

* In the ''Webcomic/{{Housepets}}'' storyline "Let's Imaginate ''Literature/AndThenThereWereNone''", the police inspector played by King [[https://www.housepetscomic.com/comic/2014/02/28/how-every-murder-mystery-ends/ insists on doing this]], despite, well, [[TenLittleMurderVictims the clue's in the title]].

* ''Series/TheAfterparty'' spends the season following a complex (if comedic) murder mystery, and the season finale naturally has this.

* In a parody in the ''WesternAnimation/{{Futurama}}'' episode "Anthology of Interest I", this was referred to as "the accusing parlor". It appears again in "The 30% Iron Chef".
-->'''Farnsworth:''' TO THE ACCUSATORIUM!

* ''Series/MarriedWithChildren'': Parodied, as with many other detective tropes, in the NoirEpisode "Al Bundy, Shoe Dick". After Al has been [[FrameUp framed for the murder]] of an old rich man, he gathers the man's family and ends up accusing all of them of being the real murderer. His reasoning is either non-existent or hilariously faulty (like accusing a man with two hook hands of holding the murder weapon, or a retarded man of being a criminal mastermind), until he does prove himself with a bit of deductive logic that the FemmeFatale did it.

* In ''Comicbook/WonderGirl'' vol 3 #2, part of the [[BatFamilyCrossover Wonder Family Crossover]] ''Comicbook/TrialOfTheAmazons'', Cassie addresses the queens of the three Amazon tribes and their bodyguards.

* Happens in each of the Albert Finney/Peter Ustinov ''Literature/HerculePoirot'' movies. This includes ''Literature/DeathOnTheNile'', even though the book just had Poirot explain his conclusion to the killers and a couple of others, not the whole boat. Lampshaded in [[Film/DeathOnTheNile2022 the 2022 movie]] where Poirot admits this trope is just so he can show off to everyone how clever he is. [[LetsGetDangerous By this stage however he's not playing games]]; he has the crew lock everyone in the room and stands guard over the only exit with a .45 automatic in his hand.

* Daniel Craig's Benoit Blanc gives an impromptu one in ''Film/KnivesOut''.

* ''Literature/TheNakedSun'': Personal contact is a taboo on Solaris, so Detective Baley has to gather the suspects via a holographic conference call and send his robot assistant to arrest the murderer. Baley uses the trope to force a confession [[spoiler:from Leebig and thereby [[FramingTheGuiltyParty frame him for the murderer]], having realized that Leebig had [[SympatheticMurderer manipulated the real killer]] and was plotting far worse crimes.]]

* Gets a sci-fi twist in ''Literature/TheNakedSun''. Personal contact is a taboo on Solaris, so the detective has to gather the suspects via a holographic conference call. When the murderer is exposed, his robot partner then goes to arrest them.

* Happens in each of the Albert Finney/Peter Ustinov ''Literature/HerculePoirot'' movies. This includes ''Literature/DeathOnTheNile'', even though the book just had Poirot explain his conclusion to the killers and a couple of others, not the whole boat.

* ''Manga/CaseClosed''. Played with a lot since Conan, as a child, has to use Kogorou as a sort of mask in order to reveal the truth, by knocking him out, slumping him over something for a generic "deep thought" pose, and using a voice-changer to talk like him. Not always the best idea since sometimes, these suspects aren't very willing to just stand and watch the man reveal everything.

* ''Manga/DetectiveConan''. Played with a lot since Conan, as a child, has to use Kogorou as a sort of mask in order to reveal the truth, by knocking him out, slumping him over something for a generic "deep thought" pose, and using a voice-changer to talk like him. Not always the best idea since sometimes, these suspects aren't very willing to just stand and watch the man reveal everything.

* ITV's ''Series/{{Poirot}}'' and ''Series/{{Marple}}'' not only adapts the Summation Gatherings from the novels, but often adds them to stories that did not originally have them (such as ''Dumb Witness'' and ''Literature/MurderIsEasy'') and sometimes expands upon them so that ''all'' the suspects are present, instead of just a few like in the novels (''Literature/TakenAtTheFlood'', ''Literature/LordEdgwareDies'').

* Parodied in Neil Simon's ''Film/MurderByDeath''. Lionel Twain calls together the world's five greatest detectives and issues them a challenge: to solve a murder that hasn't yet occurred. At the end of the movie, they go through this trope five separate times, as each detective claims to have solved the murder and tries to prove that they're right.

* ''Series/DeathInParadise'': Detective Poole makes a habit of gathering all the people involved in the [[BodyOfTheWeek murderer of the week]] to identify the killer. In Season 3, his replacement Detective Goodman is startled at being prodded to do a summation gathering in Poole's style, but decides to keep the tradition going in later episodes.

* ''Series/DeathInParadise'' has this as standard operating procedure. Lampshaded when Poole's SuspiciouslySimilarSubstitute Goodman is startled at being prodded to do one in his predecessor's style, but decides to keep the tradition going in later episodes.
--> '''Goodman:''' Camille, would you do that thing where you gather everyone together? I [[NotSoAboveItAll rather liked that]] last time...

* Parodied in ''Literature/TheConditionsOfGreatDetectives'' as Tenkaichi demands a dramatic enough summation at the end of each episode to keep the audience happy. Fujii felt that calling people who were clearly not the murderer and not involved to the summation, so there's only two people at the end of the first episode. Tenkaichi refuses to explain who did it until enough people are gathered (including a girl walking her puppy) and even then [[spoiler:he didn't get a chance to reveal who was the murderer]]. Afterwards everybody leaves before he can explain how the LockedRoomMystery occurred except an old woman who didn't understand why anybody should care.

* ''Radio/BleakExpectations''' series five opener, featuring a country house soiree at which [[TenLittleMurderVictims guests keep dropping like flies]].

* ITV's ''Series/{{Poirot}}'' and ''Series/{{Marple}}'' not only adapts the Summation Gatherings from the novels, but often adds them to stories that did not originally have them (such as ''Dumb Witness'' and ''Murder Is Easy'') and sometimes expands upon them so that ''all'' the suspects are present, instead of just a few like in the novels (''Literature/TakenAtTheFlood'', ''Literature/LordEdgwareDies'').
