Mystery novels have long fascinated readers with their blend of suspense, intrigue, and clever twists. From classic Agatha Christie mysteries to modern Gillian Flynn psychological thrillers, the genre continues evolving and captivating audiences worldwide.

The key to writing a successful mystery novel is knowing how to create suspense and intrigue, capable of dragging readers into an increasingly thick web of secrets and twists.

In this article, we will explore the essential techniques and strategies for creating a mystery novel that will captivate readers, holding their attention from beginning to end. Let’s go!

Mystery novel definition

Before analyzing how to write a mystery novel, we have to first define what a mystery novel is.


What is a Mystery Novel?

A mystery novel, often referred to as a whodunit or detective fiction, is a genre of literature characterized by its focus on solving a crime or unraveling a puzzle. Typically, these novels feature a central mystery or crime that drives the narrative, often involving a detective, amateur sleuth, or protagonist who must use their wits and investigative skills to uncover the truth. The plot of a mystery novel typically includes elements such as suspects, clues, red herrings, and plot twists, leading to a climactic reveal or resolution at the end of the story.

Let’s now analyze in detail the characteristics of a mystery novel and how to write it.

How to write a mystery novel: #1 Crafting a compelling plot

Central to any successful mystery novel is creating a compelling plot that keeps readers guessing until the final resolution. The plot has to lead readers to discover the truth through a labyrinth of clues, suspicions, and revelations.

At the heart of the plot lies the central mystery or crime that drives the narrative forward, serving as the focal point around which the story unfolds. This mystery sets the stage for the protagonist to begin a quest searching for the truth.

The key to crafting a compelling plot is finding the right balance between intrigue and revelation, keeping readers on the edge of their seats as they eagerly await the final twist.

Key stages of mystery novel’s plot

A well-structured plot typically follows a series of critical stages, each essential to the development and resolution of the mystery.

  1. The story begins by introducing the crime or mystery, drawing readers into the novel’s world and setting the stage for future events. This initial phase is crucial for establishing the stakes and generating intrigue, enticing readers to delve deeper into the story.
  2. As the plot progresses, the protagonist takes center stage. They start an investigation to uncover clues, interrogate suspects, and unravel the mystery’s secrets. This phase is characterized by tension and suspense as the protagonist encounters obstacles and challenges, testing their resolve and determination.
  3. Finally, as the story reaches its climax, the puzzle pieces begin to fall into place, leading to a dramatic resolution where the truth is finally revealed. This climactic moment is the culmination of the protagonist’s journey, marking the end of the mystery and providing closure for both the characters and the readers.

How to write a mystery novel: #2 Developing complex characters

By focusing on the development of complex characters, writers can create a richer, more immersive mystery novel.

Characters who are multi-dimensional and relatable add depth to the narrative, making the story more compelling and keeping readers invested in the outcome.


At the core of most mystery stories is the protagonist, often a detective or an amateur sleuth, whose unique skills, flaws, and personal motivations drive the investigation. Developing a memorable detective requires attention to detail, from their backstory and personality traits to their methods of solving crimes.


Equally important is the antagonist, whose actions and motivations are central to the mystery. A well-developed antagonist should have a compelling backstory and clear motives, making them more than just a villain but a fully realized character. Understanding the antagonist’s perspective can add depth to the story and create a more engaging conflict.

Supporting characters

Supporting characters also play crucial roles in a mystery novel. These can include suspects, witnesses, allies, and even secondary antagonists. Each character should have a distinct personality, background, and set of motivations that contribute to the complexity of the plot. These characters can provide red herrings, clues, and additional layers of intrigue, keeping readers guessing about their true roles in the mystery.

Character evolution

When developing characters, it’s important to balance their strengths and weaknesses, making them relatable and realistic. Characters should evolve throughout the story, responding to the challenges they face and revealing different facets of their personalities. This growth can make the characters more engaging and the story more dynamic.


Dialogue is another crucial aspect of character development. Through dialogue, characters can reveal their thoughts, emotions, and intentions. Writing realistic and engaging dialogue helps bring characters to life and can also serve as a tool for advancing the plot and uncovering clues.

How to write a mystery novel: #3 Building suspense

Suspense is the lifeblood of any mystery novel, crucial for keeping readers deeply engaged with the story. Building suspense effectively requires a combination of pacing, strategic reveals, and the careful management of information.


One of the most important elements in creating suspense is pacing. A well-paced mystery novel balances fast and slow moments, creating a rhythm that keeps readers intrigued. Rapid sequences filled with action or significant discoveries can raise tension, while slower scenes can provide necessary breathers, allowing readers to absorb information and anticipate what’s coming next. Alternating between these speeds can prevent the story from becoming predictable, maintaining a sense of urgency and momentum.


Ending chapters or sections with cliffhangers is a tried-and-true technique for maintaining suspense. By concluding with an unresolved issue or a surprising revelation, you compel readers to continue turning the pages. These cliffhangers can be as subtle as a mysterious phone call or as dramatic as a sudden confrontation, but they should always leave the reader wanting more.


Foreshadowing is another powerful tool for building suspense. By subtly hinting at future events, you can create a sense of impending doom or excitement. This technique keeps readers on alert, making them aware that significant developments are on the horizon. Effective foreshadowing plants clues that are later revealed to be significant, rewarding attentive readers and adding depth to the story.

Timing and delayed Information

The strategic withholding of information is essential in a mystery novel. By delaying key revelations, you can build suspense and maintain intrigue. This technique involves giving readers just enough information to keep them engaged while holding back critical details that are revealed later in the story. The timing of these revelations is crucial; too early, and you risk losing suspense; too late, and you might frustrate readers.


Keeping the plot unpredictable is vital for sustaining suspense. While it’s important to lay down a trail of clues, the journey to solving the mystery should be filled with unexpected turns. Introduce red herrings to mislead readers and create false leads, but ensure that the ultimate resolution is logical and satisfying. The balance between predictability and surprise is delicate; you want to keep readers guessing without making the plot feel arbitrary or unfair.

Emotional Engagement

Lastly, emotional engagement plays a significant role in building suspense. When readers care deeply about the characters and their outcomes, every twist and turn in the plot is heightened. Develop characters that readers can empathize with, and place them in perilous situations that evoke genuine concern and anticipation.

How to write a mystery novel: #4 Choosing the right setting

The setting of your mystery novel should complement the tone and themes of your story. Whether it’s a foggy, Victorian-era London, a small, sleepy village with hidden secrets, or a bustling modern city with a dark underbelly, the setting should serve as a backdrop that enriches the narrative.

Think about locations that naturally lend themselves to mystery and suspense—places with history, secrets, and an inherent sense of intrigue.

A well-crafted setting becomes an integral part of the storytelling, adding depth and complexity to your narrative.

Creating Atmosphere

Atmosphere is the emotional tone or mood of a scene, and it plays a crucial role in building suspense. Use descriptive language to create a vivid picture of the setting, focusing on sensory details. Describe the eerie silence of an abandoned house, the oppressive heat of a tropical jungle, or the chilling wind of a coastal town at night. These details help to immerse readers and evoke the desired emotional response.

Utilizing the setting to enhance the plot

The setting can be more than just a backdrop; it can be an active element in your story. Incorporate the environment into the plot by using it to create obstacles, hide clues, or enhance character interactions. For example, a dense forest can serve as a hiding place for a crucial piece of evidence, or a maze-like mansion can heighten tension during a cat-and-mouse chase. The setting can also reflect the internal states of your characters, with stormy weather mirroring turmoil or a peaceful garden symbolizing calm.

Historical and Cultural Context

If your mystery novel is set in a specific historical period or cultural context, ensure that the details are accurate and well-researched. Authenticity in the depiction of historical settings or cultural nuances adds depth and credibility to your story. It also allows you to explore unique aspects of the era or culture that can influence the mystery, such as societal norms, available technology, and historical events.

Mood and Tone

The mood and tone of your novel should be consistent with the atmosphere you are trying to create. A dark, brooding tone can be enhanced by settings that are shadowy and filled with ominous sounds, while a lighter, more adventurous mystery might feature brighter, more dynamic environments. Use the setting to reinforce the overall mood of your story, ensuring that it resonates with the themes and emotions you wish to convey.

How to write a mystery novel: #5 Incorporating clues and red herrings

A critical element of a successful mystery novel is the strategic placement of clues and red herrings. These elements keep readers engaged, encouraging them to solve the mystery alongside the protagonist while maintaining an air of unpredictability.

By incorporating clues and red herrings, you can create a mystery that is both challenging and rewarding for readers. The balance of true clues and false leads keeps the narrative intriguing, maintaining suspense and engagement until the very end.

Placing clues strategically

Clues are the breadcrumbs that lead readers and the protagonist toward solving the mystery. These should be introduced at key points throughout the narrative to maintain interest and forward momentum. When placing clues, consider the following:

  • Subtlety. Not all clues should be obvious. Some can be hidden in plain sight, requiring keen observation to identify their significance.
  • Relevance. Each clue should have a purpose, contributing to the unraveling of the mystery. Irrelevant details can frustrate readers and distract them from the plot.
  • Variety. Use different types of clues—physical evidence, witness testimonies, inconsistencies in alibis, or revealing conversations—to keep the narrative dynamic and engaging.

Balancing obvious and subtle clues

Achieving the right balance between obvious and subtle clues is crucial. Too many obvious clues can make the solution too predictable, while overly subtle clues can confuse readers and make the resolution feel unearned. A mix of both keeps readers on their toes, providing moments of revelation and satisfaction as they piece together the puzzle.

Using Red Herrings

Red herrings are false leads or distractions that divert attention away from the true solution. These are essential in creating suspense and maintaining the mystery’s complexity. Effective red herrings:

  • Mislead without deceiving. While red herrings should mislead, they must still be plausible within the story’s context. Avoid making them feel contrived or unfair.
  • Enhance the plot. Red herrings should add depth to the story, contributing to character development or subplots, rather than serving as mere distractions.
  • Resolve satisfactorily. Ensure that red herrings are resolved by the end of the story, providing closure for the reader. Unresolved red herrings can leave readers feeling unsatisfied.

Ensuring Logical Resolution

As you weave clues and red herrings throughout your narrative, it’s essential to ensure that the mystery’s resolution is logical and satisfying. Every clue should fit into the final solution, and the resolution should feel both surprising and inevitable. Consider these tips.

  • Plan ahead. Outline your mystery in advance, knowing where you will place each clue and red herring and how they will contribute to the resolution.
  • Foreshadowing. Use foreshadowing to plant hints about the true solution, making the resolution feel earned and credible.
  • Avoid excessive use of coincidences. While coincidences can occasionally drive the plot forward, relying too heavily on them can make your story feel unrealistic and damage the logic of your narrative.
  • Consistency. Maintain consistency in character actions and motivations. Ensure that the behavior of the characters aligns with the final resolution.
  • Avoid deus ex machina. Avoid relying on convenient or contrived plot devices (deus ex machina) to resolve the mystery, as this can feel unsatisfying for the readers.

Engaging the reader

Engage readers by encouraging them to solve the mystery alongside the protagonist. Pose questions, present multiple suspects, and reveal new information gradually. This interactive element can make the reading experience more immersive and enjoyable.

How to write a mystery novel: #6 Examples and case studies

Examining successful mystery novels can provide valuable insights into the genre’s techniques and conventions.

By analyzing these works, we can learn from master storytellers how to write a mystery novel.

Agatha Christie’s “Murder on the Orient Express”

Agatha Christie is renowned for her intricate plots and memorable characters. “Murder on the Orient Express” is a prime example of her skill in crafting a mystery that keeps readers guessing until the very end.

  • Complex characters. Each passenger on the train has a unique background and potential motive, creating a web of suspicion. Christie’s ability to flesh out multiple characters within a confined setting adds depth and intrigue to the story.
  • Clues and red herrings. Christie plants clues and red herrings throughout the novel. The resolution is surprising yet logical, demonstrating how well-crafted misdirection can enhance the mystery.
  • Atmosphere. The claustrophobic setting of the train enhances the suspense, and the winter storm trapping the passengers intensifies the sense of urgency and danger.

Arthur Conan Doyle’s “The Hound of the Baskervilles”

Arthur Conan Doyle’s Sherlock Holmes series is a cornerstone of the mystery genre. “The Hound of the Baskervilles” showcases his talent for blending Gothic atmosphere with detective fiction.

  • Setting and Atmosphere. The eerie moors and the legend of the supernatural hound create a chilling atmosphere. Doyle’s vivid descriptions immerse readers in a setting that feels both real and otherworldly.
  • Pacing and Suspense. Doyle maintains a steady pace, balancing moments of high tension with quieter, investigative scenes. This keeps readers engaged while gradually building to the climactic reveal.
  • Holmes’ Methods. Holmes’ logical and methodical approach to solving the mystery contrasts with the story’s supernatural elements, grounding the narrative and providing a satisfying resolution.

Gillian Flynn’s “Gone Girl”

A more contemporary example, “Gone Girl” by Gillian Flynn, demonstrates how modern mystery novels can incorporate psychological depth and unreliable narration.

  • Character complexity. The novel delves deeply into the psyches of its two main characters, Nick and Amy. Their flawed, multi-dimensional personalities add layers of intrigue and unpredictability.
  • Unreliable narrators: Flynn’s use of unreliable narration keeps readers guessing about the true nature of the characters and events. This technique adds complexity and suspense to the narrative.
  • Plot twists. “Gone Girl” is renowned for its shocking plot twists, which are meticulously foreshadowed yet still manage to surprise. Flynn’s ability to subvert expectations keeps readers on edge throughout the novel.

Raymond Chandler’s “The Big Sleep”

Raymond Chandler’s “The Big Sleep” is a classic example of hard-boiled detective fiction, showcasing the genre’s gritty style and complex plotting.

  • Dialogue and style. Chandler’s sharp, witty dialogue and vivid prose create a distinctive atmosphere. His writing style is integral to the novel’s appeal, enhancing the mood and characterization.
  • Moral ambiguity. The characters in “The Big Sleep” often operate in a morally gray area, adding depth and realism to the story. This complexity makes the characters more relatable and the plot more engaging.
  • Intricate plot. The novel’s plot is famously complex, with numerous twists and turns. Chandler’s ability to weave multiple storylines together creates a rich, layered narrative that rewards careful reading.

Tana French’s “In the Woods”

Tana French’s “In the Woods” exemplifies how modern psychological thrillers can combine character-driven stories with compelling mysteries.

  • Character development. French’s focus on the psychological depth of her protagonists adds emotional resonance to the mystery. The characters’ personal struggles are intertwined with the investigation, making the story more engaging.
  • Atmosphere. The novel’s setting—a small Irish town with a dark past—creates a haunting atmosphere. French’s evocative descriptions draw readers into the world of the story.
  • Ambiguity and unresolved questions. “In the Woods” leaves some questions unanswered, which can be polarizing but also adds to the novel’s realism and depth. This ambiguity encourages readers to think critically and engage with the narrative on a deeper level.
