All of my Geneva Chase mysteries take place in Fairfield County, Connecticut. I like that setting because it allows me to show the broad disparity between the haves and the have nots. Plus, it’s got a New England flavor and yet it's close to New York City. The setting for my latest book, EXIT SIGNS, is upstate New York in the dead of winter. I used to live there, and I know that from September until about April, it’s cold, gray, and spooky as hell.
In mysteries, familiar tropes like quirky investigators, plot twists and red herrings often steal the show. But behind every great detective, behind every puzzle, there lies something equally important yet often overlooked: the setting. In mystery writing, the setting is not merely a backdrop. It is an active, breathing element that sharpens tension, deepens mood, and influences every layer of the narrative.
In almost any storytelling, setting is far more than a place where the novel takes place. It’s atmosphere. It’s tone. It’s the shadow in the forest, the strange noise in the attic, the musty smell of the basement, and the creaking of the floorboards that makes the reader’s heart pound. Whether it’s the fog-choked streets of Victorian London in the Sherlock Holmes stories or the idyllic yet sinister mountains in C.J. Box’s tales, the setting creates a framework for suspense to thrive.
Setting does more than add ambiance—it can be its own character. Think of the locked-room mystery (which can also be thought of as a familiar trope): a classic device where the confines of a space become the key to the puzzle. In these stories, the setting isn’t just where the crime occurs; it is the problem.
The setting of a story helps build atmosphere. Shadows falling across a motel wall, a thunderstorm rumbling in, a town filled with suspicious characters. They are tools to create a visceral reaction. Readers feel unsettled not just by the mystery, but by the texture of the world they’re navigating. In psychological thrillers especially, the setting often reflects the inner turmoil of characters.
Cultural and historical settings also expand the possibilities of mystery. Stories set in unfamiliar locales or time periods bring with them unique rules, customs, and obstacles. The Edgar winning novel, FIVE DECEMBERS takes place just prior and during World War II, starting in California and ending in Japan. James Kestrel uses the setting to set the tone for a range of emotions, unease and terror. Stephen King set his book JOYLAND in an amusement park on the coast of North Carolina in 1973. There’s nothing spookier than an amusement park after it’s closed. I can vouch for that. I worked in a traveling carnival during the summer of... 1973.
Finally, setting helps readers suspend disbelief. When the world feels real, the stakes feel real. A well-rendered setting immerses the reader so deeply that even the most unlikely plot twist feels plausible. The setting anchors the mystery in a world that makes sense—until, of course, it doesn’t, and that’s where the magic happens.
