History Recap / FateGrandOrderEvent28MurderAtTheKogetsukan

* GenderNeutralWriting: In the NA version, the protagonist is only referred to with gender neutral pronouns in a dream.

* PaperThinDisguise: Moriarty's called "Professor M" in the event proper. However, you note that he antagonizes Holmes at every opportunity, even laughs when his counterpart Sherigham gets offed early. Even if you don't know his name, anyone with familiarity with the lore would figure out the identity.

AllForNothing: In a way. Sadly, this all canonically happens before the lostbelts, which means that, no matter what happened to the families after this, all was washed away by the Foreign God attacking Earth.

* DyingClue: Chris gives two after his murder, first wrote "mor" with his blood then broke his prized watch he got from Ann so it stopped at 11:25. It's deduced he was trying to write a clue to his killer's identity and the time was approximately when he was killed. It's originally believed he was trying to write "morris", but Moriarty notes it was more likely he was trying write "mom" but couldn't finish writing the last "m" and left it a "r" before he succumbed.

* RedHerring: Morris is seen at first as Chris' killer until his corpse was found. Then Eva has seemed as the guilty one until she reveals that Harriet was the mother. This one is due to the protagonist subconscially thinking that [[spoiler: Raikou]] was Eva due to how the former [[spoiler: kept calling herself mother.]] Finally, Mash thought Ann was the culprit due to being Chris' mother.

* RedHearing: Morris is seems at first as Chris' killer until his corpse was found. Then Eva has seemed as the guilty one until she reveals that Harriet was the mother.

* FeudingFamilies: The Violets and Goldies are rival crime families who have fought for years for control over a certain city. While the heads have decided to bury their feud by marrying their families together due to a new enemy attacking both of them, they both know a good portion of their members wouldn't agree thus they are going on this trip in secret. It's this reason that Juliet goes through with the marriage despite hints that she's in love with the person the protagonist is possessing

** In the backstory, Harriet's father arranged her marriage to Adamska.

* ArrangedMarriage: The Violet and Goldie families are attempting to create an alliance with an arranged marriage between their eldest children. The murders keep changing who will get married till it's Laurie and Cain.

* SelfDisposingVillain: [[spoiler:After confessing to the murders, Harriet collapses and dies from taking poison]].

* WhamLine: [[spoiler:Eva calls Harriet "Mother" at the end of the penultimate chapter]].

* FairPlayWhodunnit: Because the entire event originally hinged on the players deducing the correct culprit to get in-game rewards, it's structured to give them a chance at figuring it out by merely paying attention to the family dynamics and working from there.

* PerceptionFilter: Somehow, the protagonist sees characters differently from how they actually are in real life. Holmes notes this before his [[{{TheSummation deduction of the events}}]], to give the players a clue as to who the culprit really is.

* {{Irony}}: Holmes' FakingTheDead could have only worked if Hawthorne, who looks like Moriarty to the players, played.

* SecretKeeper: Hawkthorne actually knew "Sheringham" faked his death so that the mystery can be solved.

* PaperThinDisguise: Moriarty's called "Professor M" in the event proper, and antagonizes Holmes at every opportunity, even laughs when his counterpart Sherigham gets offed early. Even if you don't know his name, anyone with familiarity with the lore would figure out the identity.
