Acquiring Murder Weapons

Much of what drives the plot of a murder mystery are the problems with a murderer who wishes to avoid capture has to solve. In no particular order, the big ones are:

  • Finding an opportunity to commit the murder
  • Planning how to commit the murder
  • Acquiring the tools necessary for the murder
  • Committing the murder without (living) witnesses
  • If possible, having an alibi for the time of the murder
  • Disposing of the murder weapon
  • Disposing of the corpse (I’m including making it look like accident/suicide here)

(Some of these problems are really alternatives to each other; for example if one has an alibi for the time of the murder, one doesn’t need to bother with disposing of the body. If one can acquire the murder weapon in an untraceable way, one can leave it next to the corpse with a label “murder weapon” helpfully attached to it. Etc.)

In writing a murder mystery, these are the questions the writer needs to answer and—at least the way I work—before writing the actual mystery. Actually, let me back up for a second and explain by way of my theory of murder mysteries:

A murder mysteries is actually two stories: a drama told backwards, and a detective story told forwards.

I think it’s fine to write a murder mystery by the seat of one’s pants as long as it’s only the detective story one is “pantsing”. If you’ve written the drama (the murderer’s story) ahead of time, you can’t get into too much of a mess with the detective story. Where people go wrong is in not having first figured out the drama in its natural order so that they can gradually tell it backwards. (NOTE: there will be people who can successfully write murder mysteries in a completely different way. I’m not trying to lay down laws everyone must follow.)

That’s what I mean by needing to figure out the murderer’s solution to his intrinsic problems first. Once you’ve figured out how the murderer has planned his murder, you can then work out how the murder actually happened, at which point you now have a coherent story for the detective to detect. I find this order of doing things very helpful for two main reasons:

  1. This mirrors reality; it’s the order in which murders actually do happen. This means that there’s precedent for it being a workable system.
  2. One has complete freedom for the first decisions one makes. And it’s in the murder itself where plot holds are the most damaging to a murder mystery. Thus starting here gives one the fewest temptations to try to hide a plot hole in order to preserve what’s already been done.

This also lets you decide ahead of time, in a coherent way, what mistakes the murderer made (i.e. what evidence they left), so that you know where to direct your detective to look.

Types of Murder Weapons

So, the question I want to consider is how the murderer acquires the murder weapon. There are several categories which each have their advantages and their shortcomings:

  1. Ready to hand
  2. Store-bought
  3. Home-made

A ready-to-hand murder weapon, such as a kitchen knife used to murder someone in the kitchen, has the benefit of being untraceable, since there is an obvious explanation for what the kitchen knife was doing there. The downside is that such things are unreliable and so unlikely to be in a planned murder. (Of course, one can always abscond with the knife beforehand then bring it so that it looks like it was snatched up in the heat of the moment.) Ready-to-hand weapons are also very likely to be simple—knives, pokers, hammers, etc. People very rarely leave loaded guns, crossbows and bolts, etc. lying about. This means that ready-to-hand weapons will require one to get very close to the victim and use a great deal of physical force. This eliminates squeamish murderers. And most modern people are pretty squeamish.

A store-bought murder weapon is likely to be in good working order and quite possibly useful for killing at a distance and without much force. The downside is that they are—at least in theory—traceable. Guns, crossbows, etc. have serial numbers. Shop keepers have memories and many big box stores have comprehensive video surveillance. Acquiring these things in an untraceable way can be done, but it takes far more work and premeditation, since the best bet here will be to buy them on the secondary market, in cash, months or better yet years before the murder. This requires a very patient—or lucky—murderer.

Home-made murder weapons offer a good compromise between ready-to-hand and store-bought. Building supplies like plywood, hinges, rubber bands, and so on are basically untraceable. And there are a ton of very deadly weapons one could very realistically make. If you don’t believe me, just watch a few episodes of The Slingshot Channel. The downside here is that one requires a fairly competent murderer with at least a few tools. The problem this introduces is one of personality: people who are patient and good at problem solving just don’t seem like the murdering sort. However much of a problem the victim is, there’s probably also a non-lethal way around the problem they pose.

Accomplices Make Everything Easier

One practical way around most of the problems brought up in the murder weapon section is an accomplice. Even better for the problem of murder weapon acquisition is the anonymous accomplice. As long as the murder weapon isn’t directly traceable to a name (i.e. isn’t a new gun/crossbow recently bought at a gun/bow shop), this will greatly obfuscate the trail of the weapon. If the detective doesn’t know whose footsteps to retrace, he will have a very hard time retracing them.

An anonymous accomplice can also go a long way in solving the problems of personality introduced by the choice of a murder weapon. Two people can be more patient than one, an accomplice who wouldn’t murder anyone himself might still help a lover or friend to buy or make a weapon, and so on.

(In fact, the ability for two people to have two personalities is sometimes revealed in just this way—the detective is talking about the contradictions in the murderer’s behavior and someone says, “It’s like our murderer is two different people… wait a minute!”)

Of course, this introduces its own set of problems since now the relationship must be explained. I think that the most typical motivations for the assistance are:

  1. Romantic interest
  2. Financial interest

Though this makes sense since they are the two big motivations for nearly everything and especially for nearly everything which is really bad. The other big motivation in human life is religious zeal, and while you probably could come up with a story in which a radical Muslim murders a Jew out of religious zeal, it would be hard to come up with a story in which he wanted to conceal it (though you could have friends do that over his objections) and in the current environment I doubt that such a story would be well received.

There is another way in which accomplices make things easier, though: being twice as many people they make twice as many mistakes—that is, they leave twice as many clues. Worse yet from the perspective of the murderer and better yet from the perspective of the detective, they can have the motivation to double-cross each other.

As with all solutions to a problem in a murder mystery, an accomplice solves some problems and causes others. This is why it’s better in real life to always do right, of course, because then all of your problems will at least be good problems to have, but in fiction it’s what has made mystery such an enduring genre.

The Evolution of Scientism

There’s a curious thing which happens to those who believe that the only real knowledge comes from science: they start to believe that nearly everything—except what they want to reject—is science. Ultimately this should not be shocking, since people who live with a philosophy will invariably change it—gradually—until it is livable.

The people who become Scientismists generally start out extremely impressed with the clear and convincing nature of the proofs offered in the physical sciences. It would be more accurate to say, with the few best proofs in the physical sciences which are offered to them in school—but the distinction isn’t of great import. In practice, most of the impressive results tend to be in the field of Chemistry. It doesn’t hurt that Chemistry is a bit akin to magic, with the astonishing substances it allows people to make, but what it’s really best at is interesting, counter-intuitive predictions. Physics, at least as presented in school, generally allows you to predict simple things like where a thrown object will land or how far a hockey puck will skid on the ice. These aren’t very practical, and the results tend to be intuitive. Chemistry, by contrast, involves the mixing of strange chemicals with the results ranging from anything to nearly nothing to things which glow to explosions to enormously strong plastics.

And Chemistry does this with astonishing accuracy. If you start with clean reagents and mix them in the appropriate steps, you actually do end up with close to the right amount of what you’re supposed to end up with. If you try to run a physics experiment, you’ll probably be nowhere close to correct simply because the experiments are so darn finicky. I still remember when my high school honors physics class broke into groups to run an experiment to calculate acceleration due to gravity at the earth’s surface. The results were scattered between 2.3m/s and 7.3m/s (the correct answer is 9.8m/s).

The problem for our budding Scientismist  is that virtually nothing outside of chemistry and (some of) physics is nearly as susceptible to repeatable experiment on demand. Even biology tends to be far less accommodating (though molecular biology is much closer to chemistry in this regard than the rest of biology is). Once you get beyond biology, things get much worse for the Scientismist; by the time you’re at things like morality, economics, crime & punishment, public decency, parenting and so forth, there aren’t any repeatable controlled experiments which you can (ethically) perform. And even if you were willing to perform unethical controlled experiments, the system involved is so complex that the very act of controlling the experiment (say, by raising a child inside of a box) affects the experiment. So what is the Scientismist to do?

What he should do, of course, is realize that Scientism is folly and give it up. The second best thing to do is to realize that (according to his theory) human beings live in near-complete ignorance and so he has nothing to say on any subject other than the hard sciences. What he actually does is to then declare all sorts of obviously non-scientific things to be science, and then accepts them as knowledge. Which is to say, he makes Scientism livable. It’s neither rational nor honest, but it is inevitable. In this great clash of reality with his ideas, something has to give—and the least painful thing to give up is a rigorous criteria for what is and is not science.

Telling Reality From a Dream

“What if real life is actually a dream?”  is a favorite question of Modern philosophers and teenagers who want to sound deep. It’s a curious thought experiment, but in reality—that is, when we’re awake—we can all easily tell the difference between reality and a dream. But how? The answer is, I think, very simple, but also telling.

Thought experiments aside, we can tell reality from a dream because—to put it a little abstractly—reality contains so much more information than a dream does. Anything we care to focus on contains a wealth of detail which is immediately apparent to us. Whether it’s the threads in a blanket or the dust in the corner of the room or just the bumps in the paint on the drywall, reality has an inexhaustible amount of complexity and detail to it. And what’s more, it has this even in the parts we’re not focusing on. Our eyes take in a truly enormous amount of information that we don’t exactly notice and yet are aware of.

Dreams, by contrast, are very simple things. They do feel real while we are in them, but I think this comes from two primary causes. One is that we’re so caught up in the plot of our dream that we’re not paying enough attention to ask ourselves the simple question, “is this a dream?”

And I think that this is because dreams are natural to us. We often lose sight of this fact because dreams are involuntary and strange. But many things we do are involuntary, in the sense of sub-conscious; our breathing is most involuntary and our heartbeat always is. Our stomachs go on without our concentrating on them and our intestines wind our food through them whatever our conscious thoughts may be. Merely being involuntary does not make a thing unnatural. And since it is natural to us to dream, it is natural that we do not ordinarily try to escape our dreams. As with our other bodily functions, we ordinarily do what we’re supposed to do.

The other reason that dreams feel real to us is because our attention is so focused in a dream that we never consider the irrelevant details. If you ever try to call a dream back in your memory, though, you’ll notice that you can recall almost no detail in them—detail which was irrelevant at the time, I mean. The things in dreams only have properties where one is paying attention. The enormous amount of information we can see without paying attention to it is missing. This is also why they have a “dreamlike” quality to them—if we turn away then come back, they may not be the same because they stopped existing while we weren’t looking at them.

Dreams lack this stable, consistent, overwhelming amount of information in them precisely because they are our creations. We can’t create an amount of information so large that we can’t take it in.

And here we come to the fitting part: the difference in richness between reality and dreams shows what inadequate Gods we are. Our creations are insubstantial, inconsistent wisps. We can tell reality from a dream at a glance between it only takes one glance at reality to know that we couldn’t have created what we’re looking at.

(Note: This is a heavily revised version of a previous post, Discerning Reality From a Dream.)

The Influence of Art

Over at Amatopia, Alex talks about The Influence of Art. As usual, it’s worth reading. Unfortunately, Alex fails to make the critical distinction which everyone else always fails to make when discussing the influence of art: moral influence versus behavioral influence.

This distinction is most clearly distinct when considering violence versus pornography. Violence is a behavior. It can be immoral, as in the case of murder, or moral, as in the case of self defense. Pornography, by contrast, is inherently immoral because pornography specifically includes its purpose within its definition.

When people talk about whether violent video games cause people to be violent, they never specify what sort of violent video games. Do games in which people act in strictly moral ways, such as defending themselves and others or participating in a just war, make them more likely to act in immoral ways, such as committing murder or arson? Well, why would it? Let’s consider another case where people engage in morally justified violence: a surgeon’s job is to engage in morally upright violence—they slice people’s bodies open with knives. Does anyone think that this practice of justified violence makes surgeons desperate to commit unjustified violence? This is ridiculous even to suggest. Yet it is the same sort of suggestion; we don’t think that surgeons wander the streets slashing away with daggers and swords because of their frequent exposure to cutting people.

And if this sounds like an absurd example, that’s only because it’s an example of an absurd idea. Suggesting that violent video games make people violent is absurd precisely because it is confusing an action—violence—with a moral dimension—justification for violence.

By contrast, consider pornography, which contains its immoral object within its definition. Pornography is art which is designed to arouse sexual desire at an object which is not the proper object of sexual desire. Exposing oneself to pornography and using it to indulge in lustful behavior is training oneself to direct sexual energy at objects other than those it should be directed at (one’s husband or wife). It is obvious how this will have an effect on behavior because it consists in training oneself to misuse a faculty. It repetitively breaks the link between the sexual act and its proper use; it violates the habit of looking only at one’s spouse as one’s spouse.

And if we look at other cases of people repetitively misusing sex, we expect them to misuse sex. We do not expect someone who engages in many one-night stands to be faithful in marriage. Nor do we expect a (voluntary) prostitute to be faithful in a marriage. Granted, they will loudly proclaim that it’s not impossible. Which is true, but unimportant. Liars will very loudly proclaim that just because they were lying the last twenty three times, they could be telling the truth this time. And so they could. But the fact that a great many people want respect that they haven’t earned is of no consequence to the present subject.

Making this distinction solves the entire problem. It is not that art has no effect, or art has complete control over the viewer, or that art has 15% control. Art affects the viewer, but it affects the viewer along several dimensions. It affects them in what they do, and it affects them morally. I’ve no doubt that people who play violent video games with morally justified violence will be at least a little less sensitive to the sight of blood and the sound of gunfire, but that could easily mean that they are slightly more able to help people during a terrorist attack. Immoral video games, by contrast, will train people to act a little worse when they get the chance.

As is always the case with morality, it is not enough to ask what a man is doing, you must also ask why he is doing it.

Review: Whose Body?

Whose Body? is the first of Dorothy L. Sayers’ novels featuring her justly famous sleuth, Lord Peter Wimsey. There’s something which might almost be called a tradition in detective fiction that the first novel featuring the detective is not the place to start reading them, and though it is a good book, Whose Body? is not an exception. The author doesn’t really know his character in the first book, or more properly, characters—half of what makes a detective great are usually his friends and occasionally his enemies. As such things go, Lord Peter does come onto the scene in Whose Body? close to fully formed. Still, I would recommend start with Strong Poison or Cloud of Witness first.

With that out of the way, Whose Body? is a good mystery as well as a good Lord Peter story. It has a great deal of wit in it, both in wry observations as well as some excellent scenes involving Lord Peter’s mother, the Dowager Duchess of Denver. The mystery unfolds at a good pace, with new things for the reader to think about coming regularly. There is also the pleasure of reading about Lord Peter’s 1920s luxury. Though set contemporaneously, they are now period fiction, and Dorothy L. Sayers paints the scene vividly enough to work as period fiction for the modern reader. It is certainly a must-read for any Lord Peter fan.

(If you don’t want spoilers, don’t read any further.)

Analysis of the Story

(Note: please take everything that I say following in light of Whose Body? being a good novel. The purpose of this section is to try to learn from a master (Sayers) at work. Anything which sounds like harsh criticism should be taken merely as economy of speech.)

In light of some of Sayers’ later triumphs—such as Have His Carcass and Gaudy night—in Whose Body? she is clearly still finding her way with Lord Peter and detective fiction in general in. It is important to bear in mind the relativity of that statement, because Whose Body? is still superior to most other writers’ polished detectives. But none the less, Whose Body? is more conventional and ultimately a little hesitant.

By more conventional, I mean that it follows the conventions of detective fiction more closely than do the other Lord Peter novels. Though that is a somewhat strange thing to say given that in 1923, detective fiction wasn’t that old. A Study in Scarlet (the first Sherlock Holmes story) was published in 1887, a mere 36 years earlier. Granted, detective fiction exploded after Sherlock Holmes, but the explosion was still in its relatively early days in the 1920s. But none the less there were plenty of conventions at the time, and Sayers did follow them more closely than she would later.

Part of this is also related to the distinction between short story mysteries and mystery novels. I’ve talked about his before, but the short explanation is that short story mysteries are quite commonly brain teasers, while novels are the story of a detective at work. This follows necessarily from the length. In the quintessential mystery short story, the detective comes onto the scene of a crime, takes in the clues, then realizes the solution to the problem and explains it. The shortness of the story allows the reader to take in all of the clues, then pause to consider them before finding out whether he guessed correctly. (This, by the way, is why in television shows the detective suddenly realizing the solution to the problem after somebody says something which stirs his imagination is so common. I.e. why there’s the classic, “wait, say that again. You’ve solved it!” moment. After laying out the clues, they had to give the audience time to think about it, and it can’t be a new clue which solves the case for the detective, so something has to be the trigger for the detective realizing who did it so we can get to the reveal.)

This is structurally impossible in a novel, however. If the reader is given all of the information he needs in order to solve the mystery in the first ten pages of the novel, the rest of the novel becomes pointless and the brilliance of the detective becomes impossible to believe when it takes him 200 pages to figure out what any intelligent reader already figured out. Accordingly, the clues have to be revealed slowly, throughout the book, for the book to remain interesting. That forces the book to be about the process of finding the clues, rather than purely about understanding the clues presented in a jumble.

(This, incidentally, is one of the problems in the first Filo Vance novel, The Benson Murder Case. The author presented us with all the evidence we needed to know who the murderer was in the first chapter, and so the rest of the book dragged on a bit. Granted, Philo Vance also figured out who the murderer was in the first chapter, which made it a little odd that he didn’t tell anyone until the last chapter.)

Whose Body? does not give us all the evidence we need up front, but it does give us enough evidence early on so that we can make an educated guess fairly early. This does not spoil the fun as subsequent evidence is required to really substantiate the guess, and we get the fun of finding it out along with Lord Peter. It does, however, lessen the impact of the red herrings. The biggest of which is Cripsham and his pince-nez which were found on the corpse. There are several pages spent on speculating about Cripsham after he answers the advertisement Lord Peter put in the newspapers, but none of it is really credible at this point. There’s far too much we already know and/or suspect about Sir Reuben Levy’s connection to the corpse in the bathtub, and the latter’s connection to—if not yet to Sir Julian Freke, at least to the hospital next door to the corpse. Granted, it’s a little unfair to hold against a book that it’s too well written to have the second half of the book make the first half of the book a waste of time, but mystery has always been a self-conscious genre. And it is, so the idea that the murder was committed by a character as yet completely unknown and wholly unrelated to anyone already in the novel is not really credible. The result is that the extensive speculations about Cripsham just feel like a waste of time. In fact the whole affair of the pince-nez was over-played. Since the body was clearly arranged by the murderer, it was not plausible that the pince-nez were any sort of solid clue. Since they had to be either a practical joke by, or an attempt at misdirection on the part of, the murderer, they were never going to lead anywhere directly. The only really plausible connection they could have to the murderer was pointing to the murderer’s enemy. As soon as the owner of the pince-nez was utterly unconnected with anything or anyone else in the book, they couldn’t really have pointed to the murderer’s enemy, so they had to be merely a practical joke.

The character of Inspector Charles Parker was very interesting in this book—it is perhaps his best role in any Lord Peter book. I can’t help but think that Sayers never really thought that Parker worked. He continued to appear in Lord Peter stories, but he got ever-smaller roles. I wonder whether this may have stemmed from the fundamental contradiction in the role which Sayers gave him and the way she began to characterize him. Parker read theology in his spare time, which was an extremely interesting thing for a police inspector to do. It also set things up wonderfully for him to be a contrast in personality with Lord Peter who, while well educated, was an instinctive atheist. As Sayers put it more than once, Lord Peter would have thought it an impertinence to believe he had a soul. That would be a fascinating contrast.

Unfortunately, Parker’s main role was to be the Watson to Lord Peter’s Holmes. What makes this so unfortunate for the characterization which Sayers started to give Parker is that the ninth rule of Ronald Knox’s 10 Commandments for Detective fiction is commonly held to be true:

The “sidekick” of the detective, the Watson, must not conceal from the reader any thoughts which pass through his mind: his intelligence must be slightly, but very slightly, below that of the average reader.

That simply does not work for an interest in theology.

I should note that this is not actually a strict requirement for a Watson. The purpose behind this rule is that the detective must have some reason to explain himself. A beloved sidekick who doesn’t understand what’s going on and who constantly asks for explanations works very well for this job, hence it’s popularity. However, merely thinking differently will suffice. Thus an intelligent person with a different background from the detective works well. “I would have assumed it meant [plausible inference], but I’m guessing you conclude something different from it?” It’s more difficult since there must generally be two plausible inferences to pull this off, but it’s very doable. In fact, Sayers herself did this with the introduction of Harriet Vane. While not Lord Peter’s equal, she was generally the most intelligent person in any room he wasn’t in. But she had a very different background and personality from him, and so they complemented each other in just this way.

The only other thing I want to remark on was the interactions with Sir. Julian Freke. Lord Peter’s obsession with fair play and giving the murderer a chance to commit suicide before being taken was something I was glad that Sayers abandoned. I think she did it in only two cases. One was of course Whose Body? and the other was The Unpleasantness At the Bellona Club. It was perfectly fair to give Lord Peter his weaknesses, but this one just didn’t work. It wasn’t out of character, exactly, but neither did it feel like it was in character. Granted, Lord Peter tended to approach mysteries purely as a game, but  anguish at realizing that it was real was probably as unpleasant for the reader as it was for the character. The big problem being that this is all a game for the reader. Consulting detectives are not realistic. If one is going to indulge in them at all, one should see the fantasy through to the end. The detective has undertaken to put right, by a right use reason, what was put wrong through a misuse of reason. He may conclude that justice would be better served by letting the murderer go, but it is not right for him to conclude that justice would be better served by not serving it.

And to be fair to Sayers, she did abandon this line of thought pretty quickly. Whose Body? is the only time Lord Peter gave the murderer the opportunity of escape. In The Unpleasantness At the Bellona Club, he merely gave the murderer the opportunity to shoot himself before he was taken for murder and hanged. Granted, this is offensive to my Christian principles which holds suicide to be intrinsically evil, but it did at least still serve justice, if it served nothing better. And fortunately Sayers abandoned it entirely in her other stories.

Sir Julian Freke’s letter to Peter was also a little odd. First, it was strange he hadn’t prepared the bulk of it immediately after the murder on the assumption he would get away with it and the details should be preserved immediately for their scientific value. Second, it was largely a recapitulation of what we had already learned. Rather than being satisfying, I found it made for dull reading since we learned very little from it. It served in place of the denouement in an Agatha Christie where Poirot gathers everyone together and explains what happened, but with none of the revelation of when Poirot does it. There were no details commonly assumed to be one way but then put straight. There were barely any details even filled in—unless you count such trifles as the cotton wool placed under the surgical bandage to avoid bruising. Or that the bath running was to cover the sound of work rather than to actually bathe one of the corpses. And I think it’s telling that Sayers never repeated the many-page confession in her other books. Except possibly Inspector Sugg—who wasn’t really a character—no one learned anything from this confession.

In conclusion, Whose Body? is a fascinating first story for a detective. It clearly did a good job of introducing Lord Peter in 1923, and set the stage for some true masterpieces of detective fiction. It wasn’t uniformly great, as were some of Sayers later works, but where it was good it was very good. And I find it interesting that the character which changed the least in subsequent books was the Dowager Duchess. While Lord Peter took a little refinement through the books, Sayers really nailed the Dowager Duchess from the first page which contained her.
