On the 15 (and a half) Types of Impossible Crimes

There’s been no end to the ingenuity of the impossible crime genre. When you see murders committed inside of perfectly sealed rooms, and stabbings in virgin snow where the killers leave no footprints, you’re only taking the daintiest of baby-steps down the iceberg of magic murders. Take a few steps further and you’ll find yourself barreling into the realms of animated murderous snowmen, disappearing hotel rooms, witchery, teleportation, telekinesis, premonitory dreams, apparitions, flying men, transmogrification, impossible golf shots, men dying from falls when there’s no elevated surfaces for miles, time travel, people running through solid brick walls, and even the apparently magical disintegration of a man in front of witnesses. All of which, mind you, must be explained through perfectly human means without reliance on far-fetched science-fiction technology or preternatural agency — or, if sci-fi tech and ghostly happenings are commonplace in your world, their rules must still be adhered (and are usually exploited to establish the impossibility…). A whole world of man-made miraculous murders that would have the skeptics of our world taken aback! When you imagine the impossible crime problem, you imagine a scenario which absolutely cannot be taken at face value, and which the characters in the story have to battle with the reality of, whether it’s through disproving the supernatural or an ostensible suicide. There’s an impossible crime tale for damn near every insane scenario under the sun a person could think of.

…Or so I said in On a Defense of the Impossible Alibi Problem. A perfectly good introductory paragraph, wasted.

The impossible crime tale seems to be a favorite of people looking to create taxonomies. From solutions to situations, the impossible crime sub-genre more than any other seems to invite people to create lists trying to chronicle every little manner of plot, style, and form that exists. You might argue that this is a testament to the sheer formulaicity of the impossible crime story, or a testament to the magnetism of its versatility…

Just like I’ve done before in attempting to produce a list of 50 solutions to the 3 principle impossible crime genres, I will here be attempting to produce a list of all every conceivable manner of impossible crime situation — within reason. I will only be adding to this list if I feel like the entry is all of (a.) something that meaningfully alters the presentation of the impossible crime, (b.) something that meaningfully alters the potential explanations to the crime, and (c.) categorically non-specific so to be applicable to a suitable variety of stories. This is primarily because the minutiae distinguishing two locked-room mystery situations is a lot less significant than the minutiae distinguishing two solution types — this also means I can provide less “theoretical” entries than I could before.

Over at The Invisible Event, Jim Noy has actually covered a lot of our bases on his own post a few years back on the same topic. My intention here is not to contradict him, but rather to supplement his list with a few potential entries I feel worth pointing out. I will be covering a lot of re-tread ground here, so in the interest of keeping Jim’s contributions and my own separated I’ll simply be listing Jim’s entries first in one set and then mine at the end. I’ll be supplementing each category with a paragraph or two explaining the concept too — just so that this is my post, and nobody else’s!

Without further ado…


1.) The Locked-Room Mystery

The grandfather of mystery fiction and the perennial favorite of all impossible crime aficionados, locked-room mysteries scarce warrant an introduction. You have a murder committed within a room locked, sealed, and barred from the inside so that every entry is blocked-off. The only key to the room is inside of the victim’s pocket, so the killer must be still inside of the room… and yet they are not! The implication is that the killer has someone walked through the walls or vanished into thin-air…

This is the most popular form of impossible crime, and examples are a-plenty. Edgar Allan Poe’s “Murders in the Rue Morgue”, popularly (and debatably) considered the original detective story, Clayton Rawson’s Death from a Top Hat, and John Dickson Carr’s The Hollow Man (also known as The Three Coffins) all features killers who seem to vanish into mid-air within a locked room…

1.5.) The Judas Window Locked-Room

Not, perhaps, a separate situation altogether, but a prominent enough sub-sub-subgenre to warrant mention, this is one of those “Doylist Impossibilities” I invoke in On a Defense of the Impossible Alibi Problem. The situation is entirely the same as a traditional locked-room mystery, with one caveat: there is a single suspect locked inside of the room with the victim, so that it appears entirely impossible for them to be innocent of the murder! The situation is only impossible if you, as the reader accept the condition that this person is innocent and the murder must’ve been committed by an external agency.

I’ve named this one after the most prominent example, John Dickson Carr’s The Judas Window. This situation is a favorite of many cases of the Phoenix Wright: Ace Attorney video game series in which you defend clients falsely accused of murder — more often than not, this accusation comes as a direct consequence of the defendant being locked in the same room or sealed in the same general location as the victim. Edward D. Hoch, the “Master of Short Stories”, also produced more than a handful of these, such as “A Shower of Daggers”.

2.) Footprints in the Snow

…or sand, or dust. These crimes involve a man found murdered in a vast expanse of snow! The killer definitely murdered the man from close-quarters, and the man was murdered after the snow had finished falling… so how could the killer have committed this murder without leaving his footprints in the snow!? A killer who can somehow float over the snow…

John Dickson Carr dealt with the problem most notably in The White Priory Murders, and his French-speaking disciple Paul Halter also wrote these in, among others, The Lord of Misrule and The Gold Watch. Christianna Brand produced one of these in Suddenly at his Residence using dust, and Arthur Porges’s “No Killer has Wings” and Hal White’s “Murder at an Island Mansion” are two examples of this problem on sandy beaches.

3.) Psychological Impossibility

We’re starting to get into the abstract. A man’s death is caused not by direct murder, but instead by a behavior that is so absurdly unbelievable it defies every known principle of human psychology! The most famous example of this is Father Ronald Knox’s “Solved by Inspection”, which involves a man who starves to death in a room surrounded entirely by safe-to-eat food that he could’ve eaten at any moment.

4.) Impossible Physical Feats

Humans are constantly displaying their infinite capacity for improvement. Records are always being broken, and the human condition forever expanding. But in these stories, these feats of athleticism swerve from the superhuman straight into the supernatural. A man cannot run from California to New York in a matter of hours, neither can a man leap from the top of the Eifel Tower and land with not a single scratch on his body…

The Stingaree Murders by W. Shepard Pleasants features a knife that’s hammered into the wooden boards of a boat so tightly that not even Mike Tyson himself could remove it without causing significant damage and creating noise that would assuredly not go unnoticed — naturally, the knife is removed. Death in the Dark by Stacey Bishop tells of a baffling murder in which a killer is somehow able to make an eagle-eyed shot at his victim in pitch-black darkness! Impossible Bliss by Lee Sheldon involves a nearly-impossible perfect golf shot from a nearly-impossible angle that not even the most seasoned of pros could achieve!

5.) Killer Rooms

Without fail, every single time a man sleeps in the bed in room 405 of the Dickson Inn, he never wakes up… and is found the next morning, having died of heart failure at precisely midnight… The killer room involves spaces that seem to have the uncanny ability to indiscriminately cause death without human intervention. Even more baffling, these situations may have bizarre, hyper-specific conditions under which these deaths occur…

Impossible-crime-oriented BBC drama Jonathan Creek has an episode episode titled “Mother Redcap” involving an inn where bizarre deaths seem to constantly occur within the same room, at the same time… Max Afford’s “The Vanishing Trick” involves a “kinda haunted” room that constantly swallows up servants and sends them to God-knows-where…

6.) Invisible Murderer

A murder who is mysterious able to pass under your nose without detection, strangle a woman in plain view of a crowd of hundreds without being seen, and murder in rooms guarded on all sides. This impossible problem involves the situation of a murderer who is able to defy detection even when the situation dictates that they would be seen.

Such an impossible crime makes up the principle murder of Christianna Brand’s Death of Jezebel, in which a murder is committed in front of a crowd of hundreds of spectators to a medieval pageant at top of a tower, the only viable entrance to which was also in view of the audience. Derek Smith’s Whistle up the Devil features a murder in a jail cell whose sole door was observed by the narrator and a reliable witness at all times the murderer must’ve walked through the door, and yet neither of them saw any such killer…

7.) Vanishing

Whether person or object, the problem of an impossible vanishing involves something disappear when there’s no reasonable way for this to occur. While it can often overlap with locked-room mysteries, footprint mysteries, or invisible criminals, this class of impossible crime also accounts for people vanishing in front of witnesses like a magician, or thefts of objects while in another character’s hands…

Roger Ormerod’s More Dead than Alive features a world-renowned magician who seems to disappear impossibly from his locked-and-sealed laboratory. Edward D. Hoch wrote multiple stories featuring a Great Thief-cum-Detective Nick Velvet, including the impossible caper “The Theft of the White Queen’s Menu” in which three impossible thefts occur: the theft of a roomful of furniture in a matter of just a few minutes, the theft of a roulette wheel from a crowded casino and yet nobody saw it leave, and the theft of rival thief The White Queen’s menu while it is held in her hands! Quite spectacularly, Paul Halter’s story “The Celestial Thief” involves the disappearance of all of the stars in the night sky as an astronomer is watching them from his telescope!

8.) Materialization

Diametrically opposite the previous category, impossible materializations involve the production of an object or person where it very well could never have been! A man manifesting within a sealed room, a plane appearing in the sky when it had nowhere from which it could’ve come, and poison appearing within a test-tasted dish…

James Yaffe’s “The Case of the Emperor’s Mushrooms” involves the murder of Emperor Claudius of Rome, who dies to a plate of poisoned mushrooms — quite mysteriously however, the royal food-tester had eaten a portion of the food without dying, and so the poison must have appeared while in the emperor’s hands…

9.) Prophecy, Clairvoyance, and Predictions

The fortune-teller tells you that you will die on June 4th, 2022 at 5:25 PM… and, lo and behold, you find yourself dead at the appointed time! People coming into possession of knowledge which they should never have been able to learn makes up this class of impossible problem.

There are, in fact, two real-world examples. “The Greenbrier Ghost” of West Virginia is a story about a woman who divines knowledge of the cause of her daughter’s death when the young women’s death was named natural. “The Horse Room” involves a group of women named the Blondie Gang who were robbing casinos blind in the 1940s, and the way they managed to cheat at horse-race betting in a room where no information could travel in or out… John Dickson Carr’s The Reader is Warned also involves a psychic predicting a murder, down to the very minute it’ll occur.

10.) Ghost, Witches, and Miscellaneous Supernatural Jiggerypokery

This, ultimately, is a “miscellaneous” category for all impossible crimes that appear to be ghosts, magic, or the supernatural at work but don’t fit into the other categories for being too specific. The appearance of a floating ghost in a room, a woman casting a spell that appears to come true, or the commission of a seance all fall into this category.

John Sladek’s Black Aura has a man suspended in mid-air and walking without any support in front of witnesses, and Hake Talbot’s Rim of the Pit features floating men, ghosts, seances, and nearly every supernatural occurrence you could hope to dream of. “Miracle on Christmas Eve” by Szu-Yen Lin involves the impossible delivery of gifts by a man who could only be Santa Claus himself… Also, suffice it to say, Scooby-Doo anyone?

11.) Impossible Technology

Mind-reading devices, hover-boards, and teleportation machines don’t exist… or do they? The impossible technology problem involves story where a piece of technology is presented as entirely genuine, but there is no scientific way for such a machine to exist. How could this bizarre feat be faked and manufactured?

In The Great Ace Attorney 2: Resolve of Ryuunosuke Naruhodou‘s third case, Twisted Karma and his Last Bow, defense attorney Ryuunosuke Naruhodou is commissioned to defend a scientist of murder. This scientist constructed a teleportation machine that’s capable of de-materializing a man in one place, and rematerializing him in another spontaneously. He was demonstrating the machine at a science exhibition when the device malfunctioned, causing the man to appear above a glass tower, suspended freely in the middle of the air! The man would then crash through the roof of the tower where it would be impossible to approach him… and yet, when the police arrive, the man was stabbed to death. Because of the location of the body, it’s only possible for your defendant to have stabbed the man before his teleportation! And so, in order to prove his innocence, you also have to prove how the entirely impossible feat of teleportation could’ve been faked in front of a massive audience…

12.) The Inverted Howdunit

One of two Impossible Alibi problems I described, this Doylist impossibility tiptoes the line between the inverted mystery (mysteries in which we know of the killer and their plot ahead of time) and the impossible crime. In the Inverted Howdunit, we are privy to the identity of the killer very early — however, unlike most such stories, in the Inverted Howdunit we only know the killer’s identity, but we do not know how they committed the crime… or how they managed to construct an airtight alibi! This impossibility hinges on knowing the identity of the killer, but it appearing nonetheless impossible for them to be guilty.

Roger Ormerod’s Time to Kill features a murder by an ex-convict — however, the ex-convict never once left the narrator’s sight during the period during which the murder must’ve taken place! In Detective Conan Volume 2, the case “Mysterious Shadow Murder Case” involves a man who committed murder while unmistakably in another country at the time… Agatha Christie’s “A Christmas Tragedy” has Miss Jane Marple describe a murder she once solved in which she knew the killer’s identity… and yet the killer had an impenetrable alibi!

13.) Suspect X

Nine people are trapped together on an island. One person wanders off, leaving the remaining eight people together in the dining room. The ninth person is soon heard screaming, and when the eight people arrive…. they find him dead! And yet, this is impossible… he hadn’t committed suicide, everybody was watching each other at all times..! Is it possible that an Xth suspect was on the island, killing them from the shadows?

Suspect X is the second “impossible alibi” problem I described in my post on the topic. This impossibility essentially dictates that, in a closed-circle mystery, the crime is only possible if you assume the presence of one extra person whose existence in the closed-circle is itself also impossible. The solution could involve explaining the presence of this extra person, or ways for the killer, who is among the original cast, to commit murder despite being under constant surveillance.

Such problems appear in Agatha Christie’s And Then There Were None, in which the entirety of the cast is dead, and all apparently murdered, while isolated together on an island; NisioisiN’s Zaregoto – The Kubikiri Cycle, in which the narrator’s friend’s computer is destroyed while every living member of the cast is together in the dining room; Derek Smith’s Come to Paddington Fair, in which the victim is shot by a bullet from a prop gun which was at one moment loaded with blanks but later loaded with live ammunition, even though every member of the cast is incapable (by alibi and testimony) of tampering with the gun.

14.) Biological Impossibilities and Illogical Causes of Death

Biological impossibilities are any mysteries in which the victim faces a death which utterly defies human physiology and logic. Initially, I was going to have a separate category for “impossible falls”, those stories in which the victim falls to their death despite the lack of an elevated surface within any reasonable distance, but I decided to consolidate those two categories hear under the blanket of “Illogical Death” since I felt like they were conceptually similar enough.

Robert Randisi’s (awful) “The Hook” involves the serial killings of women who have had all their organs removed quite impossibly, despite the presence of only a very small incision through which removing the organs so cleanly would be impossible. Both Paul Halter’s “Jacob’s Ladder” and Mack Reynolds’s The Case of the Little Green Men involve a man falling to his death despite there being no elevated surfaces nearby. John Dickson Carr’s Gur Erq Jvqbj Zheqref and the first case of The Great Ace Attorney both involve a death by curare when ingested — curare can only cause death when it enters the bloodstream, and is harmless when imbibed. Paul Halter also wrote “The Robber’s Grave” in which a patch of grass is unusually unable to grow no matter what… Soji Shimada’s “The Executive Who Lost His Mind” involves someone who was murdered only minutes ago, but their corpse suggests that they’ve been dead for years…

15.) The Lonely Boat

A boat floats in the middle of a lake with a lone fisherman in it. The fisherman suddenly keels over and dies, and when the boat is recovered he’s found stabbed to death! Such a death is impossible — it would’ve been impossible for anyone to approach the boat without attracting attention or getting wet, so how much a man wind up murdered while isolated in the middle of a body of water?

I was initially unsure about whether or not to include this one, as most variations on this problem strongly overlap with the “invisible murderer”. However, I believe this problem meets all three of my criteria in theoretically creating a significant distinction in how the crime is presented and resolved…

Such a problem occurs in Joseph Commings’s “The Spectre of the Lake”, in which two men are shot from close-range in the middle of a lake, and both of John Dickson Carr’s “The Wrong Problem” and W. Shepard Pleasants’s The Stingaree Murders, in which a man is stabbed in an isolated boat.

    Oh, well, maybe I shouldn’t reveal this because it’s a bit crackers, but I’ve been spreadsheet-izing Robert Adey’s Locked Room Murders and its supplement. Mostly so I can have a list of exactly which stories have what scenario…
    That “Illogical causes of death” covers a lot. I guess that’s where you’d file stories about impossible fingerprints, ie fingerprints belonging to no one in the closed circle (a suspect X I guess?) or to someone who is in prison, or dead.
    What would something like The X Street Murders fit under (where the weapon itself has an alibi) – materialization maybe?
    Of course the best impossible crimes mix and match from many items – the door is guarded, but the flowerbed outside the window is undisturbed. The door is locked, but the weapon can’t be found, so it seems like the murder must be supernatural.
    Seems like a solid list! I debate the inclusion of the boat one though, even having just written one (which will no doubt never see the light of day). I guess the water is what makes it different, because it adds a third dimension to approach from?

      The idea behind the boat one is that I think the water is exploitable in a way that gives the problem a new degree of solutions exclusive to it. If we accept snow, we can accept water. 😛 This is also why I included it, but not, say, a murder on an isolated airplane, because I feel like the air restricts your options without meaningfully introducing possibilities that don’t already exist with a traditional locked-room. Now, that being said, I’ve never SEEN a Lonely Boat problem that can’t also be an INVISIBLE MURDERER problem, but you know… theoretically…

      I’d say all instances of apparently phasing through something (like how in “The X Street Murders” the bullet phases through a piece of paper) are probably just mixtures of materialization and vanishing. Vanishing from one side… and materializing on the other.

        Tom, I’ve read through Volumes 14 already, and that’s lucky for you because I’d absolutely accuse of you of flirting a bit closely with spoilers here! I just got exhausted of Conan posts, and didn’t want to scare non-converts off with nothing but like 30 posts on this comic series. 😛 Yes, that case is particularly good and, I’d venture, a bit Soji Shimada-esque in the scale of its technical solution.

        As for my other thoughts…

        Volume 11 is fantastic. The inverted mystery is top-shelf, and the locked-room mystery is great. The locked(ish) room mystery of the bathroom stall in the coffee shop was stupid and unnecessary, and was one of the few non-Junior Detective League chapters after volume 6 I consider genuinely bad, but one weak story with two great stories sandwiching it. The inverted mystery has my favorite denouement in the series.

        Volume 12 was whatever. Two decent stories, one awful code-cracking one (so, in other words, a code-cracking one). The Nintendo bombing story was surprisingly good, but not amazing, and the Holmes Enthusiast case was okay, I don’t really like tricks centered around (ROT13) evtbe zbegvf.

        Volume 13 was also really good. The Gomera case wasn’t hard to figure out at all, but the impossible disappearance was still fun, and I love the presentation of the story as well as the set-piece of the murder being like a Kaiju Battle amidst the tiny city set. I’m glad to see the Junior Detective League get some good stories, because this and Library Employee are both pleasant. The Triplet Story was whatever. The Artist’s Assistant inverted mystery, I think, gets a pass for having the best *clues* of the three inverted mysteries so far, but the howdunit (because all Conan inverted mysteries do have some element of “howdunit” surrounding the alibi, which is a neat innovation) is hokey, boring, and convoluted. It’s still in my *good* stories on the merit of the cluing alone, but believe you me, I struggled with deciding where to put this one.

    Interesting you listed “The Problem of the Emperor’s Mushroom” under materialization, because I think the impossible poisoning form a small sub-category on their own. An impossible poisoning requires stricter circumstances than a regular locked room or miracle murder as the writer has to show the victim had not been poisoned before entering the locked room or had consumed anything before eating/drinking poison that left others unharmed.

    Szu-Yen Lin’s “Miracle on Christmas Eve” is a better example of materialization and, surprisingly, so is Rex Stout’s The Doorbell Rang. Nero Wolfe pulled a locked room-trick in that one, but never acknowledge as one. For similar reasons, I always felt vanished or invisible murder weapons form a sub-category of their own. Usually this has to do with the reason why it needed to disappear, which tends to be quite different from impossible thefts. On the low end, you have Ellery Queen’s The American Gun Mystery and Douglas Clark’s Death After Evensong on the other end.

    What you call biological impossibilities, I always thought of as naturalistic impossibilities and associate them with the turn-of-the-century scientific detective fiction. A precursor to R. Austin Freeman and the Realist School. The first-ever collection of impossible crime fiction, A Master of Mysteries by L.T. Meade and Robert Eustace, is filled with them (e.g. “The Mystery of the Felwyn Tunnel”).

    But enough nitpicking for one day. Great list. And look forward to part two of your Greenbrier Ghost post.

      I was going to make an “Impossible Poisoning” category, but I realized that based on Jim’s examples for the Materialization problem he considered Impossible Poisoning merely a case of *materializing* poison into impossible locations. I personally believe that the minutiae of Impossible Poisoning is a unique inter-locking of multiple categories, but like I said from the get-go my intention wasn’t to contradict Jim so I tried to be as faithful to his original 10 as possible. Also, I agree entirely with your second paragraph, except I do think that, even considering the motive, disappearing weapons are still just a sub-category of vanishing.

      As for biological impossibilities, I tried to keep it as categorically non-specific as I could manage, hence the wording I chose (and also “naturalistic” is not a word in my day-to-day vocabulary that I’d organically end up using :P).

    I could pick nits, of course — the “flying” in Black Aura is surely an impossible physical act rather than a supernatural jiggery-pokery — and I still think you’ve got at most 12 categories here, but I love the thought that’s gone into some of these.

    I’m also considering an adjunct on the “Invisible Killer” that’s simply “Invisibility” — think ‘The Problem of the Leather Man’ by Ed Hoch or ‘All At Once, No Alice’ by Cornell Woolrich, in which various witnesses swear that a man who claims to have been with someone else was in fact unaccompanied. It’s not lack of access that’s the problem so much as a simple refutation of presence

    And, yeah, Impossible Technology is an intriguing (im)possibility. So I’ll happily admit to being a little previous in stopping at a mere Decalogue 🙂

      Actually I might go further and say that any “supernatural” impossibility could be covered by other impossibilities if it’s broken down enough (I’d love to find some that don’t). The supernatural seems to fit into a layer I’ll call “framing”, ie: the suggestion that the victim committed suicide is “framing”, the same way that apparent psychic abilities might fit under either physical feats or impossible knowledge transference depending on the display. So – I’d also consider “room that kills” to be framing as well, with the situation usually being a Biological Impossibility of what caused the victim to drop dead. Impossible technology may also be framing, though I haven’t seen enough of it to know (only one I can think of is, well, a spoiler for a videogame that Isaac’s probably played). I suppose Apparent Time Travel is hard to place, but Apparent Teleportation is easier (disappearance + appearance).

        Yeah, I suppose it depends on how the supernatural problem presents itself: it could be argued that they’re a variation on Appearance if it’s about how something gains access to allow spooky effects, for example. But then you have to allow for second sight and the like, and I worry that the language used becomes both too technical and not specific enough.

        So the good news is that there are several years left in this conversation yet 🙂

      I can’t blame you for not including Impossible Technology considering that the only example I could think of exists inside of a video game most people have never even heard of. I also don’t really like the Impossible Boat one much, but I just needed something to round up to 15, even though there are probably more fitting categories I could’ve drawn from but when I wrote this post I had LITERALLY just read the Joseph Commings story and I was suffering from brainrot. And, yes, yes, I understand that impossible alibis are contentious, but if I have to rename my blog “The Alibi Apologist” to get the point across that I am standing by it I swear to God I will. 😛

      In my opinion, the real find here is “Biological/CoD Impossibilities”, which is prevalent and frequent but under-documented in my opinion. I might do a revision of this post though and iron out the kinks, because my nits have been suitably picked from all sides. 😛

        I can’t blame you for not including Impossible Technology considering that the only example I could think of exists inside of a video game most people have never even heard of.

        I’ve racked my brain to find examples of Impossible Technology, but only came up with Helen McCloy’s short story “The Singing Diamonds” (UFOs) and Ellery Queen’s radio-play “The Man Who Could Double the Size of Diamonds,” which might have inspired Bill Pronzini’s “The Cloud Cracker.” A short story with an element of Impossible Technology (rain-making rockets). And maybe “The Scientist and the Time-Bomb” by Arthur Porges.

        Sadly, not a single example of a murderer who’s seen fleeing the scene of the crime, like ’90s Jonny Quest, on a hover-board, but interesting to note only American writers have lightly touched it. I’m sure there are more examples to be found of these infernal devices in the pulpiest of the pulps, however, they’re unlikely to have the type of solution we would like to see.

        But the more I think about Impossible Technology, the more I like the idea. Just imagine Carr conjuring up the nightmarish technological impossibility of an apparently functioning, soulless and elusive robot programmed to kill – who’s witnessed showcasing amazing feats of strength. For example, the impossibility would not center on how the robot got in, or out, of a locked room, but how anyone could possibly fake tearing a heavy, solid wooden oak door out of its frame! A practically untapped reservoir of potential!
