A few things I've noticed about true crime writing, from reading too much of it and trying to understand why some of it stays with you.
The best true crime techniques have almost nothing to do with the crime itself. The crime is the reason people pick the book up. The writing is the reason they finish it. Most of the craft happens in the parts that don't involve blood or courtrooms or mug shots. It happens in how the writer renders a neighborhood, or a marriage, or the particular silence of a family that stopped talking about something decades ago.
Robert Kolker structured Lost Girls around the five women who were killed by the Long Island Serial Killer. He spent years interviewing their families, reconstructing their lives before they became headlines. The book barely mentions the killer. Kolker made a choice that most true crime writers won't make: he decided the victims were more interesting than the person who hurt them. And he was right.
Pacing in true crime works differently than in fiction. In a novel, you can build tension by withholding information. In true crime, the reader often already knows the outcome. The tension has to come from somewhere else. Usually it comes from understanding. You already know someone dies. What you don't know is how ordinary everything was the morning before.
There's a version of true crime writing that treats real people like characters in a thriller. You can always tell when a writer is doing this because the descriptions get cinematic. The killer's eyes are "cold." The victim was "full of life." These are signs that the writer has stopped reporting and started performing.
Jon Krakauer does something in Under the Banner of Heaven that I think about often. He writes himself into the investigation. You can feel him forming opinions, changing his mind, getting angry at certain institutions. Most journalists are trained to stay invisible. Krakauer walks right into the frame. It makes the book feel less like a report and more like a conversation with someone who can't stop thinking about what he found.
One true crime writing tip that nobody frames as a tip: the research is the writing. In almost every strong true crime book I've read, you can feel the volume of material behind each paragraph. The sentences are lean, but the filing cabinet is enormous. The writer chose these three details out of three hundred. You can sense the weight of everything they left out.
Sarah Koenig said something during Serial that stuck with me. She was talking about the case against Adnan Syed, and she said, "I don't know if he did it. I really don't know." That admission did more work than any dramatic reveal could have. She let the uncertainty stand, and the audience leaned in further because of it, not in spite of it.
True crime that ages well almost always treats the legal system as a character in the story. Not a backdrop, not a setting. A character with motives and flaws and blind spots of its own.
I'm not entirely sure why the podcast format worked so well for true crime. Part of it is intimacy. A voice in your headphones feels closer than words on a page. But I think the bigger reason is that podcasts unfold over time and true crime is fundamentally a story about time, about what gets remembered and what gets lost and how long it takes for the truth to surface, if it surfaces at all.
