In Star Wars Episode V: The Empire Strikes Back, Luke famously asks Master Yoda if the dark side of the force is more powerful than the light side of the force. Yoda’s answer is no, it’s not more powerful. It’s only faster. That is, one gains power more quickly on the dark side, but there isn’t more power to be gained. And, of course, that faster power comes at a price.

I’ve been wondering if there isn’t something analogous in writing, where plot holes make interesting stories easier to write.

In one sense this is obviously true. Shoddy workmanship is easier than good workmanship. On the other hand, Rian Johnson supposedly worked for weeks on the opening word crawl for Star Wars Episode VII: The Last Jedi, and the first two sentences contradicted each other. Shoddy workmanship requires less effort, but apparently it is not always the result of less effort. In any event, this isn’t what I’m wondering about.

There are two ways in which something being easier is interesting. The first is that easier things, if one keeps the results the same, require less effort and are thus more comfortable. It’s in this sense that doing a bad job is easier than doing a good job. The other way in which something being easier is interesting is if it allows one to produce better results. A lever is a good example of this: a lever allows a man who is pushing his hardest to push more weight. Or to give another example, a wheel allows a man who is pulling as hard as he can to pull far more weight. This is what I’m wondering about.

Do plot holes allow a writer of a given skill level to write a more interesting story than his skill level would normally allow?

Obviously, I mean before one gets to the end and finds out that the implicit promises of an explanation will not be fulfilled.

What makes a story interesting are questions which are raised and which the story (implicitly) promises will be answered at the end. One of the most intriguing questions which can be raised is an apparent contradiction which admits of some deeper explanation which shows that the appearance is deceiving and the contradiction is not really a contradiction. In Silver Blaze, Holmes draws the inspector’s attention to the curious incident of the dog in the night. But the dog did nothing in the night, which is, itself, the curious incident. How can this be? There seems to be a contradiction here.

The solution of this apparent contradiction is that the dog would have barked had a stranger been about, so his doing nothing was positive evidence that no stranger had come by. The apparent contradiction of an interesting-nothing was paid off, and paid off well. So well, it was imitated so often as to make its way onto a list in 1920 of tricks that should be dropped for being too well-used (Silver Blaze was first published in 1892).

Plot holes are contradictions in a story. As such, they have the appearance of being a contradiction. Until the story is over, however, the reader cannot know that there will be no explanation of them. They thus make the story more interesting, as the reader keeps trying to guess what the solution will be. This can go badly for the author, but it need not. It will only go badly if the reader remembers the plot hole when the story is over.

There are two main ways of making the reader forget that there was a plot hole in a story:

1. Distract the reader
2. Give a bad explanation

In the first case, if there are enough twists and turns and the characters no longer are concerned with the events in which the plot hole occurred, the reader may simply forget the plot hole entirely. This will work better with readers who have bad memories, but they certainly can be found. (It probably works better in movies and television.)

In the second case, if the author only gives part of the bad explanation and has the characters are seen to accept it, many readers won’t pause to think through the rest of the explanation and how it doesn’t work. The more quick-witted readers, as well as the more dogged readers, will, of course, but there are plenty of readers with little patience and not much more wit.

If the author is able to disguise his plot holes in this manner, he will have gotten the advantage of his book being more interesting while the reader was reading it. The use of this technique—possibly without the author even realizing what he is doing it—might well enable him to write books which, to an inattentive reader, seem far more interesting than they really are. In this way, plot holes may be like the dark side of the force. It’s not that they let one write better stories—clearly they don’t do that—but they may make it much faster in the learning of the craft of writing to write stories which capture readers’ interest.

And this may be why we see stories with plot holes so often.

As I mentioned in Fun Settings for a Murder Mystery, murder at a dinner party held in a mansion is one of the most iconic golden-age settings for a murder mystery. It’s so iconic that the (sort of) murder mystery board game Clue (or Cluedo, if you’re British) has exactly this setting. It was necessary, but fitting, that the movie Clue had it as well. Parodies must be instantly recognizable.

There may not be a more recognizable setting for a murder mystery. And yet, I can’t actually think of them being done very often in golden age mysteries.

I cannot think of any Sherlock Holmes stories like this, though a few came close. Of all of the Lord Peter Wimsey novels, only Clouds of Witness comes close, though that was a rented hunting lodge, not a mansion, and there was no dinner party and the murder happened in the middle of the night. I’m sure that there was at least one Poirot with this. A quick search turns up Murder in Three Acts, which has more than one poisoning at a dinner party. As I’ve mentioned, Murder on The Orient Express is similar in structure to a dinner party at a mansion, though it is, of course, a train and not a mansion. I can think of a Miles Bredon case, The Body in the Silo, which is a fairly classic example of it. I can’t think of any Father Brown stories with this setting. I’ve only read two Dr. Thorndyke stories, so I can’t speak with any authority on them. I find the dinner party plot unlikely in a Dr. Thorndyke story unlikely, though, and a quick search doesn’t turn anything up.

To be fair, I suspect that murder at a dinner party is likely to have been the plot of plays more often than of novels. They’re a fun and interesting setting for a novel, but they have a much greater benefit to a play: they put everyone into very few settings that don’t need to be changed out. As I discussed in Were Plays the TV of Previous Centuries? most of these were lost.

So, why is this setting, despite being so richly suggestive and iconic, so (relatively) uncommon in novels?

I think that the answer is that it’s hard to pull off. Especially if the murderer does not use poison, getting time alone with the victim in order to do away with him is not easy in the context of a dinner party, with cigars, billiards, tea, etc. following. The timing is tight, and that is not easy to manage with many people going about the activities of a party, even a low-key party. This is not merely a problem for the writer; it is also a problem for the murderer. There must be some reason, then, why the murderer would wait for such a difficult time to commit his murder, and moreover one that undeniably puts him, if not at the scene of the crime, at the most a room or two over from it.

Novels, being so much longer than either short stories or plays, give the reader time to think about the story. They spend time with all of the characters in a way that they don’t in a play or short story (or movie, though those are less common). The audience to a play will forgive a playwright for taking liberties with a story that are necessary to fit the story onto a stage. The reader of a novel is not nearly so forgiving because the writer of a novel does not need to take liberties to fit a story into a book.

I think that the rock upon which this setting falters, in novels, is plausibility from the murderer’s perspective. At a dinner party in a mansion is an absolutely terrible place to murder someone. All of the things which make it interesting also make it a bad plan. This can be made to work by springing the need for the murder upon the murderer—a sudden realization that he has mere minutes to silence the victim before he is ruined, for example. This is a workable condition, but a limiting one.

Another possible way of working around it is for the murderer to have as part of his plan the framing of someone. He might be killing two birds with one stone, as it were—killing the one and getting the other out of the way through a conviction for murder. That said, this was a better plot back in the golden age of mysteries, in England, where execution was common and swift. In the modern US, where execution is rare and often takes decades, the amount accomplished by framing someone for murder is less. Not nothing, though. It could effectively get a love-rival out of the way, or open up a coveted job.

In summation, I think that this is an under-used setting, which can be made greater use of, and should.

There are many types of clues in a detective story which can be left at the scene of the crime. They are often looked at from the perspective of the detective, or really of the reader, since he is on the detective’s side. I think it might be profitable to look at them from another perspective: from that of the murderer.

We can first divide clues found at the scene of the crime by whether they help the murderer or help to catch him. After that, we can divide them based upon whether they were intentional, unavoidable, or accidental.

There are not many sorts of clues which help a murderer. Aside from clues which lead to disprovable theories, by which plot a murderer can be found innocent at trial and thus protect himself by the legal prohibition on double jeopardy, all clues which help the murderer must lead the detective to suspect someone else. We can divide these up by whether they mislead to another person, or only to a trait which the murder doesn’t have.

A clue which misleads to a specific person can be desirable or undesirable from the murderer’s perspective. Sometimes a murderer hates the person toward whom the clue leads; other times the murderer may accidentally framed his fiancé. There is wide latitude here—any place on this spectrum is workable. Clues which accidentally frame the murderer’s fiancé will probably need to be accidental clues, such as the fiancé having been in the room for some other purpose before the murder took place and dropping an earring or a cigarette. On the flip side, clues which implicate someone the murderer dislikes or even hates can be either purposeful or accidental. Both can be made to work; it is not so distasteful to have luck on the side of the murderer as it is on the side of the detective. That said, it will probably be more satisfying for such clues to be intentional. Stories in which all of the complications turned out to be an extraordinary run of (bad) luck can be interesting, but they almost need to be titled Much Ado About Nothing. (Despite there being no coincidences in that play and the misunderstanding being the work of the villains.) Where such clues are by design, this tends to require quite a lot of planning on the part of the murderer, since he has to ensure that the person he’s framing has no alibi. This will almost certainly involve some risk on his part; it’s not easy to know what someone else is doing without being unobserved. Such clues will, except by very good luck on the murderer’s part, only work in a highly premeditated murder.

Clues which lead, not to specific people, but only to traits that the murderer doesn’t have give more leeway in how they are done, but are also more hard to pull off. A good example of this would be Chesterton’s story The Hammer of God. The victim was killed by a tremendous blow with a hammer, which points to an enormously strong man (which the real murderer was not). Another example which comes to mind is the Lord Peter Wimsey story Busman’s Honeymoon. In that story, the blow to the head points to an extremely tall man, which, again, the murderer was not. Come to think of it, it’s curious that both of my examples involve a blow to the head. It’s not necessary, though. It’s quite possible to shoot from a higher place than the natural standing point of the murderer, suggesting a taller person—bullets even have the advantage, if they pass through the body, of giving a second point in space to line up, showing the height more clearly.

The downside to this is that the number of traits one can indicate via evidence is limited. Height, strength, possibly in some circumstances weight—or more likely not being above a certain weight—are about all that come to mind. It would be possible to have evidence which seems to eliminate certain disabilities, though. A gunshot which requires sight, or something done when one hears a sound, or distinguishes who someone is by their voice. Those get quite special purpose, though, since the field of suspects has to get small if a blind man is the murderer and the evidence seems to rule out a blind mind. I suppose one could set a murder in a conference for the blind, but otherwise there just aren’t enough blind men around to fill up a suspect list, once the main issue of the evidence not actually ruling out a blind man is found. It’s the sort of thing which would work pretty well in a short story, but I doubt it could sustain a novel.

The other major classification of clues are clues that help to catch the murderer. These are the meat of a detective story. Without these sorts of clues, detective stories must be in vain. Clues which help the murderer are optional, but clues which hinder the murderer are mandatory. Very well, then. What can we say about clues which help the detective to catch the murderer?

I think that the most important thing to consider with such clues is that from the perspective of the murderer, they are mistakes. In designing these clues, we are choosing what mistakes the murderer will make. This will, of course, be a function of the murderer, whether this was planned, and the circumstances that may intervene.

The first category encompasses the murderer’s intelligence and imagination. There can be a pretty big variance here, though if the murderer is too lacking in either there won’t be much to investigate. The two do not even necessarily go in sync; a young murderer might be quite intelligent but not very imaginative through lack of experience. The reverse can be true as well—a murderer with wide experience of the world might be quite imaginative, though not highly intelligent. The experience would have to be relevant, though, which I think would mostly limit us to murderers who are or have been detectives. That’s a very specialized murder mystery. I suspect one could broaden it out to a person who is very familiar with the workings of a particular place, such as intimate knowledge of how a hotel or other business functions, to know who is where, when. The downside to that specialized knowledge taking the place of intelligence is that it will be harder to hide the murderer, since not many people will have that knowledge.

An interesting sub-category of intelligence and imagination would be the murderer trying to disguise a clue as something harmless and not realizing how it will look. An old school example might be a murderer flicking a burnt-out cigarette end onto the ground where there are others, and assuming that it will be taken to just be one among many. In that case the detective usually finds it either by its residual warmth or by a lack of dirt on top of it or some other sign which the murderer didn’t think would be present to indicate what it is. I’ve also seen cases where a murder thought something would be taken as belonging to the victim when a better knowledge of the victim would show that it didn’t. A good example of this would be the razor in the Lord Peter Wimsey story Have His Carcase. It would be plausible for most men that they owned a cutthroat razor (back in England in the 1930s), but minor investigation of the victim showed that he was extremely unlikely to have one. The pursuit of this clue helped to catch the murderers.

The second category is almost self-explanatory. If the murder was planned out, all else being equal there will be fewer clues in the crime scene since any quarter-way decent plan will have the avoidance of such clues as a primary consideration the forming the plan. A more impromptu murder will lend itself to the presence of more clues. In both cases, however, any clues left will have to pass the stage where the murder is leaving the scene of the crime. Unless fleeing in haste, the murderer will, presumably, look over the scene for clues to remove.

This is where circumstances can intervene to preserve clues for the detective. It can take the form of introducing something that makes the murderer flee in haste, of course. It can also take the form of something which conceals the clue from the murderer during his investigation. Something falling over in the death throws of the victim, for example, might conceal a clue beneath it. Poor lighting can also make a murderer overlook a clue during the cleanup stage. The field for intervening circumstances is very wide. Even pet animals that steal clues have been used successfully. Books that were put back when they should not have been can be a clue, or contain a clue. And of course there are the environmental clues that were so popular back in the early days of detective fiction. Things found that would not be noticed except that they were damp among dry things, or dry among damp things, or clean among dirty, or recent among moldy; the list can go on and on. Changing conditions also work well here; an unpredictable rain can show that the victim was killed before the ground was wet. Temperatures plummeting to below freezing can preserve a clue that would normally have melted away. Even the reverse is possible; hot temperatures can melt away a clue that was meant to make the murder look like suicide.

This very anemic overview of types of clues is meant only as a starting point. I’m not sure that I’m going to make it a series, but as time permits I think I’d like to go through each of these sorts of clues, one at a time, to consider them more closely. Until then, I hope that this systematization was of some interest. When writing a murder mystery imagination is key, but a little bit of order can help to pick among the vast array of possibilities.
