What Makes a Good Mystery Story?

I have discussed the basic elements of plot several times. Most plots have the ‘event’ that happens that causes the story to begin. Then, we have rising action, where the protagonist tries and fails to do the thing, and then we have the climax where the big confrontation happens, and then we have falling action, resolution or conclusion and then the end. If you can keep those things in mind, then you can write a good story. There are other things that make a story, right? Like, the ‘event’ at the beginning needs to be compelling enough to keep the reader engaged. The protagonist needs to have real stakes in the story, they can’t have just stubbed their toe. That’s not a reason for an adventure. Mysteries, however, are a whole other beast. Not only do they require to be a compelling plot with rising action, a climax and falling action, but they also need to have the mystery at the core that the reader should not be able to easily figure out. A mystery author needs to have the ability to keep their readers guessing the entire time. So that brings me to my question, what makes a good mystery story?

1-The Crime Must Be Interesting

Said another way, the crime that the protagonist is investigating should be something that the reader wants to understand. If it’s “who took my stapler,” maybe that will work, if all of the characters in the office are compelling and interesting and have reasons why they took the stapler. However, most readers of mysteries are used to murder being at the core of the story. If you don’t want to write about murder, then make the crime an interesting one. Make the characters (like I’ve already said) compelling, give them reasons why they could be guilty.

2-No One Should be too Innocent

Nothing is more upsetting to mystery readers than being able to pick the guilty person from the first chapters of the book. Or pages of the story, if it’s short. There should be some skeletons in everyone’s closet. There should be multiple possible killers or guilty parties.

If you are not a reader of mystery and you are looking to write in the genre, I would suggest that that is a bad idea, I don’t know if there is a finickier bunch of readers besides maybe sci-fi enthusiasts. If you don’t understand the tropes of the genre, or the things that have been overdone, then you aren’t going to be able to write a story that people are interested in reading.

3-There Should be Red Herrings, but not too Many

You should be able to write a story that leads readers in the wrong direction, but that also rewards careful readers. The point here is that you should use foreshadowing in such a way that when a reader gets to the end and finds out the who in the whodunit, they maybe are surprised, but they aren’t angry because they were tricked.

4-The Crime Should be at or Near the Beginning

Whatever mystery is occurring in your story, it should be right at, or near the beginning. This can happen as early as the prologue or in the first chapter. You can call the crime the ‘inciting incident’ if you want. For example in the Italian Job, the movie starts with a heist that goes wrong and one of the members of the group dies, while another one runs off with all the money.

Since that happens right at the beginning, the audience is hooked into the story and wants to get revenge along with the protagonist throughout the rest of the story. I don’t normally use movies as reference, but this one is a very easy to see example of what is meant when you’re putting the crime at the beginning. A book example would be in Cuckoo’s Calling, the very beginning of the book goes through a model dying by maybe jumping maybe falling off a balcony, and then it skips time to introduce the main character, a PI who the readers follow as he investigates the crime. In the book, the beginning leaves it ambiguous enough that the reader is unsure if the model jumps or is pushed.

5-There Should be Several Possible Suspects

We can’t have two, or three. I think at least four people that may or may not have done the crime is a good number. Just think, if you need to pick between two people, it’s a fifty-fifty chance, right? Put another person in there and it gets more interesting, but one more, and then it’s like okay…any one of these people has a reason to have done it.

I’m not saying they all need a lot of time, but well thought out reasons are good. Like, the person who was killed owed them money, or maybe there was an old grudge. Stuff like that.

6-The Victim Should be Interesting

The victim shouldn’t just be a victim. They should be a whole person. They should have an interesting life: friends, relatives, enemies. If they are an adult, they should have a job or a career. Maybe they are an addict, or they gambled. Interesting quirks or habits make them come to life (even though they aren’t alive in the book) and give you more to work with, as far as why someone didn’t want them to be alive anymore.

7-The Investigator Needs to be a Main Character

This happens in a lot of different ways. Maybe the person who is investigating is an amateur. Or maybe they are with an agency, or police, or a PI. But someone who is performing investigative work needs to be a main character. You could also have other main characters in the story. You could have the victim’s significant other, you could even do some POV from the person who committed the crime as long as you don’t give away who they are and spoil the ending for the readers. But mystery readers enjoy investigating along with the investigator, so knowing how the investigator thinks, or what they see that is unique and different from what other people see will help the story feel more “real” to the readers.

So that’s what I have so far. Let me know if you feel like there is something in the what makes good mystery story article that I missed.

Here is the list:

1- The mystery must be interesting

2-No one should be too innocent

3-There should be red herrings, but not too many

4-The crime should be at or near the beginning

5-There should be several possible suspects

6-The victim should be interesting

7-The investigator should be a main character
