Engineering a Mystery
By Beth Groundwater
I've taught a number of workshops at many different writing conference, library programs, and to writing groups, and one of my favorites is "Engineering a Mystery." I apply my engineering background from my first career to help fledgling mystery writers build some scaffolding for their projects, or formulate recipes for their mystery novels.
The first essential ingredient in a mystery is the sleuth, who investigates the murder(s) and tries to deduce who the killer is. In my case, with two mystery series in the works, my sleuths are well-defined: whitewater river ranger and rafting guide Mandy Tanner for the RM Outdoor Adventures series or gift basket designer Claire Hanover. Both of these characters are old friends, but when I switch from one to the other, I usually need to go back and read at least the last few chapters of the last book starring that character, so I remember what emotional and physical state I left her in and move on from there.
The next essential ingredient in the recipe for a murder mystery is the victim. The dead body that falls on the floor in Act One. There may even be more than one victim to keep things interesting if the plot starts to drag in the middle. Without a victim, we wouldn’t have a mystery to solve and we could all go home! Along with defining a victim, I try to give him or her a family and/or friends who will sorely miss them, because we should never forget how truly horrible murder is.
Usually the victim is not well-liked, so there are many people who’d like to see him or her dead. And, I, like most mystery writers, try to use my creativity to find an interesting way for the victim to die—a mysterious poison, a unique weapon, something that might be construed as an accident or suicide and so on.
The third essential ingredient is suspects, those people who may have killed the victim(s). There are usually between 3 and 7 suspects in a murder mystery. Detectives or amateur sleuths look for means, motive, and opportunity for suspects. All three are needed to identify the killer. Means is the ability to commit the murder, such as access to the murder weapon. Motive is the reason why the suspect wanted the victim dead. Opportunity is the potential for the suspect to be at the right place at the right time to kill the victim. And an alibi is a story for why a suspect didn’t have the opportunity. That story can be true or false.
I try to make sure that all of my suspects have at least two if not all three of means, motive, and opportunity. And bringing in suspects often drives the addition of subplots (activities the victim was engaged in that may have led to his murder) and the addition of research topics I need to study.
The fourth essential ingredient in a murder mystery is clues, pieces of evidence that help the sleuth solve the crime. A good principle that detectives use is that the killer usually leaves something at the crime scene and takes something away. What the killer leaves may be fingerprints, shoe prints, a lipstick stain on a glass, or the murder weapon, say if the knife is stuck in the body. What the killer takes away may be hairs, carpet fibers or bloodstains, money or jewelry, or a special memento of the crime. I try to sprinkle the discovery of clues throughout the manuscript, as well as conversations with the suspects, to keep the reader stimulated with more information that she or he can use to try to solve the puzzle.
The last ingredient that spices up the recipe is red herrings. These are false clues that point to the wrong suspect, such as the gun in my first mystery, A Real Basket Case, that incriminated Claire’s husband. The term comes from a fish that’s been cured in brine and smoked, which turns it red and makes it very smelly. The smelly herring then is dragged across a trail to try to distract hunting dogs from their prey. A good hunting dog—or sleuth—is trained to not be distracted by the strong false scent but to stay on the trail of its prey. What makes things interesting in a murder mystery is when a piece of evidence points to more than one suspect, so it’s both a red herring for the innocent suspect and a clue for the killer.
I like to have at least half a dozen clues and red herrings, if not more. Once all the essential elements are defined, I work on putting scenes in order in an outline, figuring out what happens when and what gets discovered when. During this process, I shuffle scenes around until I come up with a flow of events that I think will most interest the reader. And, of course, there have got to be some surprises!
It's a complex process, and one that I always find daunting in the beginning, wondering how I'll ever come up with the final product--a scene by scene outline, a set of detailed character profiles, and thorough research notes from which I can start writing. But, I have to trust in the process and my abilities. I keep telling myself that I've done it many times before, so I should be able to do it again.
