Genres Influence Audience Expectations
Audiences recognize genres through experiences gained from watching films and reading books. Although most readers can’t name a genre’s obligatory scenes and conventions, they sense when something is missing from the story’s structure, characters, plot, or theme.
Structure:
- Obligatory Scenes: The must-have scenes associated with a genre, such as the discovery of a body in a murder mystery.
- Audience Expectations: What readers expect from reading a genre. For example, the intellectual challenge of solving a murder mystery.
Characters:
- Genre-relevant Lead: A main character with relatable traits and emotions, such as in a Cozy Mystery where the female amateur sleuth overcomes her flaws to identify the criminal.
- Genre-suitable Supporting Cast: Characters who enhance the story. For example, quirky characters who add interest and humor to a Cozy Mystery.
Plot:
- Genre Conventions: Story practices that meet readers’ expectations, such as the climatic scene in a murder mystery where the sleuth exposes the killer.
- Main Plot and Subplots: Story events that follow genre-based patterns.
Theme:
- External Theme: The takeaway message at the end of the novel.
- Internal Theme: The lesson lead must learn to change.
If crucial parts of genre are left out of a movie or novel, audiences show disapproval with critical reviews.

Plot:
- Genre Conventions: A cozy mystery includes conventions that set it apart from thrillers, hard-core crime, and horror.
- In a series, the readers prefer each book solves the mystery, and they dislike cliffhangers designed to entice them to buy the next book.
- An inciting crime occurs near the novel’s beginning, and if more offenses occur, each crime increases stakes and adds complexity.
- The murder takes place offstage.
- Murderer’s reason for killing must be plausible.
- Readers expect to see every clue they’ll need to solve the mystery, and they dislike having unknown evidence interjected at the end to wrap up the story.
- Readers enjoy the intellectual challenge of legitimate red herrings that distract and confuse, misdirecting them away from clues, facts, suspects, and timelines.
- Top cozy mysteries introduce fresh twists that surprise and delight readers.
- As the contest of wits with sleuth progresses, the murderer makes it personal.
- Each story sets up a “ticking clock” that limits time to solve crime.
- The investigator is often a likable amateur female sleuth who has (or develops) an interesting reason to get involved.
- Both the sleuth and murderer have endearing qualities and flaws.
- While investigating, the sleuth encounters obstacles that increase conflicts and tension, such as a personal issue that impedes her solving the crime.
- A cozy mystery avoids profanities, explicit sex, and graphic violence because of reader expectations.
- The setting is a small town or subset of a larger city where the inciting crime happens.
- The murderer is from the same community as the victim.
- Victims are frequently disreputable, making the crime seem understandable or even justified.
- A cozy mystery series often has something that ties one book to the next, such as a trope, theme, hobby, or occupation.
- Stakes escalate because someone or something sleuth cares about is in danger.
- Main Plot and Subplots
- The investigation of the murder and victim is the Main Plot.

- Other characters reappear across the series (e.g., family, police chief, friends) and serve as the Community Conflict Subplot.
- The Sleuth’s Character Arc Subplot shows the lead character’s progressive change as she deals with issues (e.g., flaws, needs, wants, emotional wound, relationships).
- The Setting and Story World Subplot paints a charming and interesting place readers will want to revisit. This world offers opportunities to introduce more characters across the series.
Theme:
- External Crime Theme: The external theme values range from justice to injustice.
- Justice wins when the sleuth outwits the villain, which is an essential reason readers like cozy mysteries.
- Injustice wins when the villain outwits the sleuth, but that outcome conflicts with what audiences expect from a cozy mystery.
- Internal Morality Theme: The internal theme values range from altruism to selfishness.
- Good triumphs when the sleuth sacrifices her world-focused and selfish values in favor of the needs of others.
- Evil reigns when the sleuth pursues her selfish needs ahead of the needs of the cozy community.
