The Butler Did It



""Perhaps it might be even subtler, if after all it was the butler.""

- Edward Gorey

A Dead Unicorn Trope in murder mysteries.

The stereotypical example is that a bunch of people are invited to a dinner in a wealthy man's house, and the wealthy man is poisoned while they are all eating dinner. All the guests debate who among them is the killer, only to discover at the end of the story that the killer is the butler, whom nobody bothered to think twice about; he's just part of the furniture, as if the table was the culprit.

The butler is the avatar of the most unlikely suspect that, of course, turns out to be guilty because the author wasn't creative enough to come up with a better way to surprise the reader. It's the mystery writer equivalent of the Ass Pull, except that you can see it coming a mile away, making it, for modern readers, The Untwist. Ironically because this trope is so well known, when an 'actual' butler is involved he rarely 'did it' or when he did it is down as a parody and Played for Laughs.

The expression "The butler did it" was probably coined by novelist Mary Roberts Rinehart, although it's likely to be a real-world example of Beam Me Up, Scotty. The earliest verified explicit statement of disapproval dates to S.S. Van Dine's 1928 essay "Twenty Rules for Writing Detective Stories" (it might be noted that these rules would disqualify the authors who defined the genre, including Wilkie Collins, Edgar Allan Poe, and Arthur Conan Doyle). This article explores in detail the origin of this strange semi-existent trope.

It is okay, however, for a butler to be a suspect, primarily to mislead the reader.

Not to be confused with A Wizard Did It.

Obviously, ending spoilers follow.

Anime & Manga

 * It isn't a mystery, the butler did it. Black Butler's Sebastian is always the killer. But everyone loves him for it.
 * It isn't always Sebastian, Grelle was playing a butler too, and no one thought it was her, murdering all those prostitutes. Then again, I guess no one suspects the Shinigami. They also don't suspect them to pretend to be butlers, ether.
 * Actually, in the anime, in almost every other arc, in the cases Ciel has to solve, it was the butler other than Sebastian that "did it". First it's  in the   arc, then there's no butler, then it's , then it's   at the end of the first season.
 * In the anime Prétear the butler Tanaka seems to be a kind man who is both The Woobie and Butt Monkey of the show.

 * 308 chapters in, Hayate the Combat Butler uses this one.. extremely literally. Although it's not murder in this case, and if he'd left things alone it would have left everyone in-character.

Comic Books

 * In Rick Veitch's Brat Pack, Big Bad Doctor Blasphemy, responsible for the deaths of... the entire cast, is revealed to be King Rad's butler Fredo in the final pages.
 * Played with by Diabolik: the actual'' butler is always innocent, but Diabolik tend to take his place (or the place of another house servant) to take a look of the place he's about to steal from and/or drug/kidnap his victim.

Film

 * The Buster Keaton film Sherlock, Jr. plays it straight, with a butler acting as the accomplice of the main villain.
 * This is what sets the plot of The Aristocats in motion, pretty much. Butler Edgar is second in line for the fortune his wealthy mistress wants to leave to her cats (or so he believes, due to a combination of Poor Communication Kills and Edgar being stupid enough to think the cats will outlive him), and so knocks them out with sleeping pills and tries to get rid of them. This being Disney, the kitties live, and then have wacky adventures before Edgar's comeuppance is delivered.
 * Of course, it's not a mystery. The audience (but not the characters) knows it's Edgar right off the bat.
 * Additionally, Edgar, while not elderly, is not a very young man, and it is possible for cats to live to be thirty. As three of the cats in question are kittens, they really could have outlived him. He also seems to forget that he would still be needed to take care of the cats, and considering that they take only very little in the form of food, litter and occasional vet bill, he'd still have himself a quite comfortable life, even if he wasn't the master of the house on paper.
 * Reportedly, the old film The Mandarin Mystery.
 * No murders involved, but Fitzwilly takes this trope Up to Eleven by starring a butler who's a Con Man criminal mastermind. Subverted in that all the other domestic servants in the household also Did It.
 * Lawrence from The Princess and the Frog is a lesser villain, but still needs mentioning; He was Prince Naveen's butler on his visit to New Orleans before he became an accessory to Dr. Facilier's plot to  It's a Long Story.
 * Technically, Lawrence was a valet, not a butler, although I don't believe either was specifically stated by Naveen or Lawrence in the film.
 * In Where The Truth Lies, Lanny believes Vince killed the girl and Vince thinks Lanny is the murderer. It turns out the butler strangled her. The reveal hurt the movie; as one critics noted the ending was "straight out of the big book of mystery clichés".
 * Gosford Park where a valet/butler tries to kill a wealthy aristocrat, but the housekeeper beats him to it!
 * The Haunted Mansion
 * The Three Stooges episode "If a Body Meets a Body".

Literature
"Russell: * affronted* Are you telling me the butler did it? Holmes: I'm afraid it does happen."

 * The Brothers Karamazov, while it is a bit more complicated, ultimately plays this one straight.
 * The butler did it in the Sherlock Holmes story "The Musgrave Ritual", although in that case it's only theft, not murder, and not the mystery; the question is why he did it, and what happened to him afterwards. It eventually transpires that he's

 * In Three Act Tragedy, the butler is the prime suspect, having disappeared soon after the murder. Turns out, but.
 * , originally written as a play, has this ending. In the book adaptation, not by Christie, it's spoiled the moment it happens by outright stating, before the detectives even arrive, that the character
 * One of Christie's short stories, also employs this trope, except that in this case the "Butler" is actually a Valet.

 * In The Dresden Files, it's not exactly the Butler, but has the Beneath Suspicion slot down pat: the traitor on the White Council isn't the Jerkass leader, the mysterious Asian, the noble Native American shaman, the Captain of the Wardens, OR Harry's Jerkass parole officer Morgan -
 * Invoked and lampshaded in The Beekeeper's Apprentice

Live Action Television

 * One Jonathan Creek Christmas special actually used this, though, as usual for the series, half of the mystery was realising that it had been a murder in the first place, and then how and why it had been done. The victim was a magician who had apparently killed herself, but it ultimately -- and appropriately -- turned out that The Butler Did It. How? It was all done with mirrors.
 * This is used in the Bones episode "Yanks in the UK", seemingly for the sole purpose of allowing them to use that line. On the other hand, it's arguably a subversion: The butler's confession conveniently stops the investigation and spares his employer's family the public scrutiny of a trial; it's unclear if he in fact "did it."
 * On one episode of The Twilight Zone, a group of people get off a bus and gather at a cafe where they are served food and drinks by the local counter jerk and dine. It is later revealed by the police that one of the people on the bus seems to have been an alien. Ten Little Murder Victims ensues, the resolution of which is only a half-subversion of The Butler Did It: one of the people from the bus was The Mole, but the cafe worker who served them all and remained very much in the background throughout the story was also an enemy alien from a different planet, and was two steps ahead of The Mole the whole time.
 * Boardwalk Empire: Parlor maid/servant Louanne is the one poisoning the Commodore.
 * Happens in Lewis and its predecessor Inspector Morse occasionally, most recently in Wild Justice. Never trust a college servant.
 * The Hardy Boys Nancy Drew Mysteries episode "Dangerous Waters" plays with this: the kidnap victim doesn't recognize her mother's butler when he greets the Hardys at the door. Naturally, he turns out to be part of the plot, and the non-recognition turns into a vital clue for Joe & Frank to crack the case.
 * Butler, Valet, Gardener... Garak has held many perfectly legitimate jobs where his employer happened to suffer a tragic end.

Tabletop Games

 * In the setting of the role-playing game Over the Edge there is a Milkman Conspiracy of butlers and personal retainers around the world. They usually don't murder their patrons, but if there was a good reason...

 * And even on a couple cases where it looks like the Butler or the housekeeper/groundskeeper could have done it because s/he had motive (Namely Billionaire Birthday Blues wherein the ) s/he is shown to be above it.

 * There was a Batman story arc where Bruce Wayne was accused of murder. One background character, upon hearing the accusation, commented "He has a butler, doesn't he?".

Stop that."


 * In Desolation Jones, the Colonel's butler is briefly suspected of being the mastermind behind the crime. Jones remarks "wouldn't it be funny if the butler did it." Nobody gets why he's amused.
 * Lampshaded in the early Mad Magazine private-eye spoof "Kane Keen," in which the detective explains that the butler is as good a suspect as everyone else is since "the butler is always the murderer." He then unmasks the butler as the true culprit: the talking dog. A cop then bursts in, breathlessly exclaiming he's figured out that the butler did it.
 * Made fun of in Archie Comics once. Archie's dad stays up to watch a movie called "Burglar of Barcelona" and is then called to answer a trivia question on who the burglar of Barcelona is, Kate or Harold. Since Archie's dad fell asleep during the movie and missed the conclusion, he can't answer and it turns out...the Butler did it.

Film
"Mr. Weissman: Right, but I think it's clear it's the valet who did it. No, because the valet has access to everybody. No, the valet isn't the butler. No, there's one butler, and there's lots of valets running all over the place. He takes care of people. He's in their rooms at night. He could do it. I mean, the valet easily could have done it."
 * Clue (1985):
 * Also, in the Clue VCR game, the butler (and narrator) is named Didit. In this case, though, he's not a suspect.

He begins speed reading through it, pauses halfway and says, "I think the chauffeur did it." He speeds through the rest of he book and, on finishing, says, "He did". Of course, as everybody knows,
 * Gosford Park is an exploration of this trope and other murder-mystery-related tropes:
 * Lampshaded when one character, an American movie maker working on a new murder mystery set in England, calls his studio:


 * The cast is separated between "above stairs" characters (the upper-class guests of a shooting party) and "below stairs" ones (their servants). During the first part of the movie, it's revealed that every single above stairs character has a reason to murder the future victim,.
 * The butler acts strangely after the murder.
 * Following the trope, the detective who investigates the murder questions the servants, but only on their masters. Later, knowing nothing of the servants, he explains that all of them are free to leave as there's no reason to suspect them. This is justified in the movie by the class mindset of the characters and the way they treat their servants (at best, like wallpaper that serves food).
 * However,
 * The 1966 comedy film The Wrong Box had a convoluted series of events centering around a dead body and cloudy circumstances of his identity and death.

The detective says - everyone now - "The butler did it?!"
 * The Haunted Mansion lampshades and plays it straight. While the butler did indeed do it  The main character immediately after invokes this trope.

He made quite a mess driving them away so everybody belives its just an excuse (he was about 9 years old). It turns out it was the, erm, nice housekeeper who is revealed as one of the burglar's mum.
 * The loyal butler Cadbury in Richie Rich was framed by the villains for the bombing of the Rich's plane to kill Richie's parents. Since Cadbury also happened to be Richie's guardian in light of Richie's parents being missing, by removing Cadbury from the picture, the villain placed himself as Richie's new guardian so he could effectively isolate Richie from the outside world.

First it's discussed, when time-traveling main character Ned muses that the mystery they're solving is nothing like old-school detective stories, where the butler always does it.

 * A spy story written by Eric Ambler in the 1930s has an author as the main character.

 * In a sketch on The Muppet Show, with Rowlf as Sherlock Holmes, the butler did it. However, because the butler is a Muppet monster, he then eats all the evidence, including the body and the only witness. Holmes therefore concludes that, in the absence of evidence, there was no crime at all (having briefly "deduced" that, in the absence of evidence pointing towards the butler, Watson did it).

 * In an episode of Castle where Castle and Beckett are having trouble figuring out a suspect for the Murder of the Week:

"Quincy: You've known [who did it] for years!"

Webcomics

 * Played with in Pv P by having the butler secretly playing the role of "hero". Creator Scott Kurtz explanation of the idea was essentially "if anyone ever discovered the secret lair beneath the mansion, they would obviously suspect the millionaire playboy as the hero's secret identity. Meanwhile, the butler would have skipped town and hired his services out to the next rich employer far away, where he would start his hero gig anew."

Western Animation
"Daffy: A likely story. I see it all now. You and the upstairs maid. 'Do the old boy in,' you said. 'Elderberry wine and old lace,' you said. And then, 'the quick getaway,' you said! Rio di Janerio, tropical nights, romance and a heavy bank account!"
 * One of the few examples that admits that it doesn't really happen is a Daffy Duck cartoon, were, after badgering the butler, Daffy notes that it's never really the butler.
 * In a classic Chuck Jones cartoon, "Daffy Dilly", Daffy attempts to enter the mansion of an ailing millionaire who has offered a million dollars for anyone who can give him a good laugh before he passes on.

 * Parodied in an episode of Cow and Chicken, where the Red Guy presents a mystery story not entirely unlike The Orient Express, to the two title characters. Interestingly while the butler clearly had a motivation to injure his employer with his own denture, Red's reasoning as to why he did it is this. Made weirder by the fact that in the very same episode, he's employed as the family's butler.
 * Subverted in the Hurricanes episode "Lord Napper of Stepney". Napper inherited his Uncle's fortune on the condition he never plays soccer ever again. It's never been stated who would be the next one to get the inheritance until Napper lost it. Until then, the only people who ever hoped to get the money were a relative and the deceased one's business partner and the two of them ever tried to rid themselves of Napper. In the end, the money went to the valet.
