What the Body Tells Us Forensic Detail and the Ethics of Accuracy
The question comes up at every panel I have ever sat on, asked with a consistency that tells you it matters to people: how much research did you do?
The subtext varies. Sometimes it is genuine curiosity — writers wanting to understand how a colleague navigated the process of learning things that are not in public circulation. Sometimes it is admiration, the assumption that extensive research is self-evidently a mark of professional seriousness. And sometimes — frequently enough to be notable — it carries a slight edge of something else. Unease. The faint suggestion that someone who knows in detail how decomposition progresses, how a particular method of violence presents in post-mortem examination, how forensic odontology is used to establish identity — someone who knows these things and has chosen to put them in a novel — has perhaps a relationship with the subject that warrants a second look.
I research extensively. I have spoken to forensic pathologists, forensic psychologists, crime scene investigators, and prosecutors whose professional lives are organized around violent death. I have read case files. I have attended academic presentations on topics that had, by that point in my career, ceased to disturb me in the way they initially had. I have asked questions that I could see produced brief, calculated assessments of my motives.
And I have thought carefully — more carefully than any panel question has quite captured — about what to do with what I learned.
The Tension at the Heart of Forensic Crime Writing
There is a genuine ethical tension in the use of forensic detail in crime fiction, and writers who treat it as simple are usually avoiding the complexity rather than resolving it.
On one side of the tension: authenticity. The crime novel's relationship with its reader is built partly on the promise that what is depicted has a grounding in reality. That the investigation proceeds as actual investigations proceed. That the evidence gathered is the evidence that would actually be present. That the scientific and procedural elements reflect how forensic science genuinely functions rather than how television drama needs it to function to fit a forty-five-minute runtime. Readers who know these things — and an increasing number do, partly because of the true crime boom, partly because forensic science has become a more public discipline — notice when fiction gets them wrong. The inaccuracy breaks the contract.
On the other side: what might be called the pornography of violence. The detailed description of harm that serves no narrative purpose beyond the detail itself. The lingering. The forensic inventory performed not because the investigation requires it but because the author has discovered that readers will follow wherever the darkness leads, and has decided that leading them deeper is easier than leading them somewhere meaningful.
The victims in crime fiction are almost always people who have been deprived of agency in the most complete way possible. A murder victim cannot consent to how their death is described. They cannot object to the level of detail deployed around what was done to their body. This is not a reason to avoid the subject — avoiding it would make crime fiction impossible. But it is a reason to ask, at every descriptive decision, what the detail is doing and who it is serving.
What You Need to Know and Why
Accurate forensic detail requires access that is not immediately available to most writers. The information that appears in crime fiction — specific to cause of death, to decomposition timelines, to trace evidence and its interpretation — does not come from Google searches or Wikipedia entries. It comes from professionals who have agreed to speak to writers, and that agreement is based on a reasonable expectation of how the information will be used.
The most important thing a crime writer can do before seeking forensic expertise is to be clear about their purpose. Professionals in forensic fields are accustomed to public curiosity that ranges from the genuinely educational to the prurient. They make assessments quickly. A writer who can articulate specifically what they need to know, and why it matters to their narrative, will receive more useful information than a writer who arrives with general fascination and no clear direction.
What you typically need to know falls into a few categories. The mechanics of death — what a particular method of violence produces in a body, what the immediate and progressive physical effects are — matters for the accuracy of your crime scene. The investigative process — how scenes are processed, what priority decisions are made, how forensic evidence is collected and chain of custody maintained — matters for the procedural authenticity of your detective's work. The interpretation of evidence — how forensic scientists arrive at conclusions, what the limitations of those conclusions are, where uncertainty exists — matters for the intellectual honesty of your narrative.
What you generally do not need, and should think carefully before including, is the granular physiological detail that exists beyond what the investigation requires. Specificity for its own sake is not research. It is accumulation.
The Difference Between Consequence and Spectacle
The test I apply to my own work is straightforward, though not always easy to apply honestly: whose experience is this scene serving?
If the answer is the narrative — if the forensic detail is establishing the specific nature of the crime, informing the detective's analysis, illuminating something about the perpetrator's psychology or method that will be significant later — then it is doing legitimate work. The reader needs to know what the detective knows in order to follow the investigation with the engagement the form requires.
If the answer is the reader's appetite for transgression — if the detail exists primarily to be disturbing, to generate a frisson that the narrative has not earned through character or consequence — then it is doing something else, and that something else warrants examination.
The distinction is not about squeamishness. Crime fiction is not squeamish, and should not be. Violence has consequences that the form has an obligation to depict honestly. A crime novel that sanitises what violence produces — that keeps its crime scenes tasteful, its post-mortems bloodless, its victims aesthetically arranged — is not being ethical. It is being evasive, and that evasiveness distorts the reader's understanding of what the violence actually means.
But there is a significant difference between depicting consequence honestly and producing spectacle. Consequence asks the reader to understand what happened and what it cost. Spectacle asks the reader to look, and implicitly to enjoy looking, which is a different invitation and a different contract.
Forensic Science as Character
The most underused aspect of forensic detail in crime fiction is not the detail itself but the scientists and specialists who produce it. Forensic pathologists, forensic psychologists, trace evidence analysts — these are people with specific professional cultures, specific relationships with uncertainty and mortality, specific methods of thinking that differ from the detective's and from the reader's in ways that crime fiction rarely explores with the depth they deserve.
The forensic specialist in most crime fiction is a delivery mechanism. They appear to provide the detective — and through the detective, the reader — with the information the plot requires. They explain the evidence and depart. Their inner life, their professional context, their relationship with the work, is rarely developed because the genre has decided they are secondary.
This is a missed opportunity. The forensic pathologist who has spent thirty years in proximity to violent death has a relationship with mortality that is distinctive and interesting. Their calibration of what is disturbing — what registers as significant versus what has become routine — is not the same as the detective's or the reader's. Their professional practice of objectivity, maintained in conditions that would be deeply upsetting to most people, is a form of discipline that crime fiction could examine with considerably more curiosity than it typically does.
What the Body Is Owed
The victim in a crime novel is almost always a body before they are a person. The crime scene precedes the backstory. The forensic description precedes the humanisation. This is, in some ways, structurally inevitable — the investigation begins with the death, and the death is physical before it is biographical.
But what the body is owed, in the crime novel's handling of it, is the same thing the person was owed in life: the minimum of dignity consistent with the narrative's requirements. Not more detail than the story needs. Not a level of description that reduces a person to their worst and most vulnerable moment. Not a lingering that the victim, if they could object, would object to.
Forensic accuracy in crime writing is a professional obligation. The ethics of how that accuracy is deployed are a moral one. Both matter, and the best crime fiction — the kind that earns its darkness rather than simply wallowing in it — takes both seriously.
The body tells us what happened. What we do with that telling is our responsibility.
