Whodunnit to Me?

Go To
Frank Bigelow: I'd like to report a murder.
Captain: Sit down. Where was this murder committed?
Frank Bigelow: San Francisco, last night.
Captain: Who was murdered?
Frank Bigelow: I was.

The protagonist has been murdered and is either dead or soon will be. The rest of the story concerns their efforts to solve the crime in the time they have left. A subplot can also be their trying to protect a loved one from the killer who did them in. This can be supernatural or non-supernatural depending on whether the protagonist is already dead or dying slowly but inevitably. If he or she is already dead, may involve Near-Death Clairvoyance, otherwise may be considered a form of Death by Origin Story. They may also possibly be hanging around as a ghost with Unfinished Business, hopefully a Friendly Ghost but a decent chance of the unfriendly kind.

A common science-fictional version involves characters who have the ability to back themselves up, through Brain Uploading or some similar technology. This is often used as a way to get around the issue that most victims know who murdered them: the version of the character that's trying to solve the murder is only as up-to-date as their most recent backup, which means they naturally have no memory of the murder or anything immediately before it.


Compare Discovering Your Own Dead Body, as this tends to be part of the evidence in the case. Contrast The Dead Guy Did It, when the deceased was the killer.

As a Death Trope, all Spoilers will be unmarked ahead. Beware.

    Already Dead 
  • Lia in Le Chevalier d'Eon, who possesses her living younger brother to find out who murdered her.
  • Given a heartbreaking spin in one of the Black Jack anime series: A girl who's given a cornea transplant from another woman who supposedly perished in an accident starts having visions of a man trying to grab her. Everything points out at the dead woman's spirit trying to contact the person who has her original cornea and tell her that she was murdered... except that her death was a genuine accident, and what the poor woman saw last was her boyfriend trying to save her.
  • In the Show Within a Show episode of Marginal #4, Atom plays a detective and Rui plays the ghost of his murdered partner. They have 24 hours to solve the case, before the ghost disappears forever.

Comic Books

  • The Shade, the Changing Man story arc 'The Road' becomes an inverse murder mystery.
  • This was the whole idea behind the DC Comics character Deadman, who died in his first story - and became a superhero as a result, fighting crime in spirit-form while investigating his own death. At one point, it looked like his killer was Joe Chill, the same thug who had murdered Batman's parents.
  • This was part of the title character's original motivation in Ghost from Dark Horse Comics.
  • Emily from Anya's Ghost wants to find the man that killed her family. Subverted later, where it's revealed there was no murderer. Aside from Emily, of course.
  • In the original graphic novel R.I.P.D. this was Nick's motivation for joining the R.I.P.D.


  • The Crow: Eric Draven rises from the grave to hunt down the criminals who murdered him and his fiancée.
  • Ghost: Sam Wheat becomes a ghost after being killed in a mugging gone wrong, and discovers there's more to his death than just making him an unfortunate statistic.
  • In the 1941 film Topper Returns, heroine Gail Richards is murdered in an Old, Dark House, only for her ghost to investigate her own death.
  • The '50s movie, You Never Can Tell tells the story of a murdered dog who was sent back by 'dog heaven' as a human to investigate his own murder.
  • The movie Oh! Heavenly Dog reverses this, sending back a murdered human in dog form to investigate his death.
  • In RoboCop, both versions, Alex Murphy tracks down the criminals who all but killed him.
  • In I, Robot, the protagonist is guided through a murder investigation by pre-programmed holograms left behind by the victim. Subverted as it turns out that the victim actually arranged his own death, intending for the murder investigation to lead the detective to evidence of a real crime.
  • Trailers for The Invisible advertised this as the premise of the movie, but in the actual film, the identity of Nick's murderer is never in question, to him or the audience. The film is thus less of a whodunit and more of a character drama.


  • Remember Me, a novel by Christopher Pike. Shari begins the novel already dead. She was killed at a party, and being a ghost she must figure out which one of her friends killed her.
  • Never Trust A Dead Man pairs this with Clear My Name and Enemy Mine: the protagonist, Selwyn, is forced to cooperate with his murdered rival (who has been brought back from the dead in the form of a bat) to find the real murderer and clear Selwyn's name.
  • 9Tail Fox by Jon Courtenay Grimwood involves a police officer who was shot from behind and resurrected in another man's body by the Celestial Fox.
  • Ghost Story, Book 13 of The Dresden Files, has this as its plot, with a ghostly Harry Dresden trying to find out who killed him, and the more important question of who ordered it done. As it turns out, the answer is...Harry Dresden. Also, he's not exactly dead...
  • James Herbert's Nobody True is told from the POV of a ghost seeking his killer ... who can astrally project to oppose him. In fact, it combines this trope with a subversion of An Astral Projection, Not a Ghost; he only got to find out whodunnit to him because he was off astrally projecting somewhere at the time of death.
  • The zombie-PI protagonist of Kevin J. Anderson's Death Warmed Over investigates his own murder along with several others. He mentions that a number of ghosts or other zombies have hired him to solve their murders.

    • Hogfather makes passing mention of a variant; apparently it's not unheard of for the Guild of Assassins to accept contracts from zombies with a score to settle.
    • The Watch has a rule where if someone comes Back from the Dead via the intervention of an Igor, the attack is still considered murder. True, they were only briefly dead, which is why the killer will be "briefly" hanged.
    • In the short story "Theatre of Cruelty", when reflecting on the difficulties with policing in a Dungeon Punk city, one of Vimes's observations is that murder investigations get really strange when the corpse is taking an interest. Discworld zombies, after all, are animated by Unfinished Business, and a strong desire to find your murderer could certainly qualify.
  • Emily Bones City Of Ghosts: Upon realising she is a ghost, Emily very quickly learns she was murdered. She immediately decides to find her murderer and take revenge, which is essentially what constitutes the plot for the rest of the book.
    Atop the Eiffel Tower stood an invisible girl and surveyed Paris, looking for her murderer.
    • The trope is also very important for the plot as Emily's murderer is a very powerful being who has long evaded detection by the forces of good, and it is precisely the fact that he murdered Emily personally that allows Emily to track him.

  • Conversational Troping in one of the vignettes in GURPS Magic Items 3, when a private eye in a Fantastic Noir world discovers his client is a Brain in a Jar, and hopes it's not another "find my killer" case. (It's not, exactly; it's "find my body".)

He's not quite satisfied with the "it was an accident" theory, but he has to put it on the back burner in favor of the job his new boss has given him.

  • {...} in Hanna Is Not a Boy's Name has been dead for a while now, and recently been shown that he was murdered. He doesn't actively pursue his killer (he doesn't like to dwell on the past), but the point stands that {...} died, he came back and his killer is still presumably at large.

    Not Dead Yet 
Comic Books
  • In the first Top 10 miniseries, a teleportation accident results in two people and their car being partially fused with a giant minotaur. The woman in the car dies immediately; her husband and the minotaur are dying slowly, and there's no way to separate them without killing them both. A large part of the issue is about discovering what caused the accident, and helping the two survivors to accept their fates. The subplot was partly inspired by an episode of Homicide: Life on the Street, listed below.
  • Tom King's Human Target miniseries features this as the driving plot. Christopher Chance, the titular Body Double/detective, gets poisoned while doubling as Lex Luthor, putting him on the hunt for whoever tried to murder his client before the poison kills him in 12 days.

  • Played with in Dead Man. The protagonist William Blake receives a gunshot wound to the chest that is slowly killing him, although he doesn't realize it.

    Blake: I'm not dead.
    Nobody: (snorts in disgust)

She decides to use the time she has to figure out who the real guilty party is. Fortunately, the guilty party in question was practically waiting around the corner to gloat to her about it and got Caught on Tape.

Live-Action TV

  • NCIS:
    • "Dead Man Walking". A naval lieutenant walks (somewhat weakly) into NCIS and asks Gibbs to solve a murder. When Gibbs asks whose murder, the lieutenant pulls out a clump of his own hair, revealing that he's been poisoned and needs the team to find out who poisoned him. Genre Savvy Tony makes a comparison by name to DOA.
    • Also when Tony gets pneumonic plague, though he doesn't die.
    • NCIS: New Orleans used this as well in "The Walking Dead". A naval psychiatrist collapses and is found to have been poisoned with polonium-210 two weeks earlier, and he will be dead in another two weeks.
  • In the Homicide: Life on the Street episode "Subway", a man is pushed off a subway platform in front of an oncoming train. However, instead of being run over, he gets wedged between the train and the edge of the platform. Essentially, the lower half of his body has been crushed, but the organs in his torso are kept in place due to him being pinned. He's dying slowly due to blood poisoning and other issues, but the paramedics say that as soon as they try to remove him, basically everything is going to fall out of his body like a leaky sack and he'll die immediately. This inspired the similar situation in the comic Top Ten, above.
  • In the Starsky & Hutch episode "A Coffin for Starsky," the guys have one day to find out who poisoned Starsky before he dies.
  • An early CSI: Miami was about a woman who was poisoned with radioactive materials by a Corrupt Corporate Executive (or rather a level employee who she seduced to get information) because she happened to be the lawyer working the joint lawsuit against their illegal dumping practices.
  • Used in CSI, when an attorney who'd been working with Sarah informs her that she won't be able to finish the case because the bullet lodged in her cranium from a previous crime has shifted inside the skull and will soon kill her. Subverted when, against all expectation, she survives the surgery to remove the bullet, which subsequently proves that she'd been shot while in the process of murdering her husband.
  • The Alexander Litvinenko case was apparently Ripped from the Headlines in Law & Order: Criminal Intent. Litvenenko is actually mentioned by name.
    • A similar, earlier case in which a fight between two Northern European naval personnel ended with one pinning the other with a piece of equipment that discharged a radioactive field, and firing. It was reported that prosecutors were faced with the difficulty of how to press charges, because a fatal dose was delivered, but murder charges could not be pressed because it would take years for the victim to die.
  • The Monk series finale: Monk is poisoned. They find the culprit fairly quickly, but need the poison. Monk still has a chance to live.
  • Person of Interest is about a Machine that can predict murders before they occur. But in the Season 2 episode "In Extremis", a computer virus is starting to affect its performance, so Team Machine arrive too late to stop the Victim of the Week from being poisoned with polonium that will kill him within a day.
  • Doctor Who had this as a significant plot point throughout Series 6, with the Doctor being "killed" in Utah in the first episode and having to find out why and by whom he was murdered, and the threads of it carried over into Series 7, as The Doctor now knew WHO did it, but was still trying to figure out the specifics of WHY, a question which was finally answered in the Christmas special "The Time of the Doctor".
  • In the Star Cops episode "Conversations with the Dead", a space freighter is knocked off course, with no way of reaching safety or being reached by rescuers before its oxygen supplies give out. The crew of the freighter interact with the cops investigating the incident by radio. Except it turns out that by a staggeringly improbable coincidence, their ship is carrying some untested experimental cryosleep chambers and the inventor of said devices just happens to overhear what's going on and steps in to help. Our heroes figure out what's probably going on quite quickly, but since all the evidence is going to take most of a decade to get back to Earth there's not much they can do about it.
  • The short-lived Timecop series had "D.O.A.", where Jack and his boss Matuzek are suddenly killed at night by a car bomb in their headquarters' parking lot. Hemmings uses the time travel equipment to go back to that morning and warn Jack of his impending demise. Jack spends the rest of the episode rushing to put the pieces together, while Matuzek (though trying to help) treats it as his last day alive and takes care of family business. They actually fail to solve the case and appear ready to follow through with history, but their investigation changed things enough to prevent the explosive from being planted. Jack later figures out the culprit was someone he met that day and saves Matuzek from being gunned down in an alley.
    • Jack also thought he was the target due to Timecop-related business, but it turned out to be Matuzek due to "ordinary cop" business (even though the culprit knew about time travel).
  • Another Time Travel version is the mini-series 5ive Days to Midnight, when the protagonist is sent a futuristic briefcase by an unknown party, containing a police file on his murder to happen five days later.
  • Castle: In the two-part seaon 6 opener, Rick is exposed to a nerve gas and given 24 hours to live. He and Beckett use the time to attempt to locate the perpetrators and recover the gas and (hopefully) the antidote.
  • Whodunnit? (UK): In "Happy New Year", the Victim of the Week is bitten by a venomous snake. Knowing he has 30 minutes to live, he uses the time to question the suspects.
  • Played with in the Father Brown episode "The Prize of General Gerard". After eating fish soup tainted with tiger's whiskers (which were earlier used to kill General Gerard), Father Brown insisted on continuing the investigation, even though he insisted he was beyond help. Subverted in that he was acting; he never ate the soup and only claimed to be poisoned to draw out the real killer.
  • In one episode of Get Smart, Maxwell Smart was poisoned by a KAOS agent, and had to race the clock to find the agent and get the cure.
  • An episode of The Mentalist has a scientist discover that a super-virus she's been working on has been released in the sealed lab. She immediately calls CBI and reports her own murder. The team spends the rest of the episode trying to track down the killer, since there's no cure for the virus. This turns into a real murder partway through, though, since the scientist dies after saying goodbye to her kid. The killer is another scientist at the lab who had been quietly stealing small quantities of the virus to sell on the black market. When a surprise inspection arrives, his plan was to cover up the discrepancy in their stock of the virus by spilling a vial of it in the lab, knowing that everyone would think the victim just made a fatal mistake and didn't want to admit it; it might have worked if not for Jane being brought in.
  • In the Star Trek: The Next Generation episode "Reunion", Klingon Chancellor K'mpec reveals that he's been gradually poisoned and will be dead soon. He asks Captain Picard to find out who is responsible, focusing on the two challengers to his soon-to-be-vacant position; Duras and Gowron. However, K'mpec's request of Picard is less about the fact that one of his would-be-successors has murdered him, but rather that they did so using such a cowardly method as poison instead of challenging him directly.
    K'mpec: (to Picard) Find the assassin. A Klingon who kills without showing his face has no honor. He must not lead the Empire. Such a man would be capable of anything, even war with the Federation.
  • Jake and the Fatman: In "I'm Gonna Live Till I Die", a mousy bookkeeper who's been poisoned spends his last days helping Jake find the rat who did it.

Video Game

  • The Flash game Sixty Seconds To Live. The title is fairly self-explanatory here.
  • In Mystery Case Files: Madame Fate, the fortune teller Madame Fate wants to find out which of her workers is plotting her death at the stroke of midnight. The answer? It's none of them as they are all found to be dead/doomed by midnight. The answer is the ghost of Charles Dalimar, the Big Bad of the series, who only gets involved because Madame Fate went to the Master Detective for help.

  • The Death of Doctor Strange: Back when Doctor Strange began his career as a sorcerer, he sealed away a portion of his soul in the event of his death, with the result that, after he is murdered by an unknown attacker, this portion would manifest in the present, representing a week of his past that will act to tie up his loose ends and solve the mystery of his death. Unfortunately, this portion of his soul has never been 'updated', with the result that he is ignorant of details of Strange's future such as his current status as Sorcerer Supreme or his membership of the Avengers.

  • The Rook features an interesting variation of this; protagonist Myfanwy Thomas received at least four warnings that she would lose her memory in her immediate future, so spent some time preparing notes for her future memory-less self that would allow her to return to her life (or pick up a new one if preferred) and work out who and what was the cause of her amnesia.
  • Altered Carbon by Richard K. Morgan is a Film Noir style thriller, with an investigator hired by the restored backup of an apparent suicide. The victim does not believe that he could have possibly wanted to kill himself; indeed it would be futile given that he was backed up and brought back to life in under 48 hours and instead believes he was murdered and demands justice.
  • A story by Jack Vance has the main character kill someone who has discovered his real identity. The backup of the person spends the rest of the book screwing him over while trying to prove that he killed them the first time.

  • At the beginning of the The Goblin Reservation, Peter Maxwell describes how he ended up on another planet during a teleporter transit, with the data stream intercepted by Sufficiently Advanced Aliens, only to be told that the stream isn't just intercepted but duplicated, meaning a Peter Maxwell has already returned to Earth, only to die in a freak accident.
  • In A Memory Called Empire Mahit has her predecessor Yskandr's Virtual Ghost loaded into her brain implant, but that backup is fifteen years out of date and had no idea his original was dead until they saw his corpse, and then had a mental breakdown and went silent. But as Mahit investigates Yskandr's death she gets flashes of his memory. She eventually does get the version of Yskander that remembers uploaded into her, but at that point the who is less interesting than the why.

  • The whole point of Higurashi: When They Cry is Rika finding out who kills her in June 1983, and consequently destroys the town. She keeps reliving the events leading up to her death in a time loop, but unfortunately is unable to keep memories of the period just before her death, so she has no idea who the killer is.
  • Umineko: When They Cry is a hard-to-classify example. At the end of the first installment, the protagonist, Battler, ends up dying in a mysterious mass murder on a Closed Circle island. He subsequently finds himself in an afterlife-like realm, and is challenged by a witch, Beatrice, to give a rational explanation for the murder. In the subsequent episodes, he is forced to play a game of wits with the witch, which involves unveiling the mysteries behind several alternate-timeline versions of the original mass murder. However, throughout all this he is actually a "player" dwelling on a higher plane of existence, while the version of his that dies in all these scenarios is just a "pawn" in a pocket universe. It's rather difficult to explain.

Alternative Title(s): Whodunit To Me
