An exploration of crime literature
To turn the page and discover new facts, expose a new suspect, uncover a betrayal, and to find a shock no one saw coming are what gives mystery and crime literature its thrill and fame. Crime literature refers to works of fiction that revolve around a mystery—a suspicious death, disappearance, or something to be investigated. The Sherlock Holmes novels by Sir Arthur Conan Doyle and Hercule Poirot novels by Agatha Christie helped establish the genre. They formed the definition of a detective and the archetype’s role within the genre. As time passed, this foundation has not eroded. Instead, it has grown through novels like /Gone Girl/ by Gillian Flynn and The Silent Patient by Alex Michaelides.
As society becomes a place where trust and humanity are limited, many use crime novels to understand what kind of situations can occur. Crime novels become cautionary works, often targeted towards young women. They offer gruesome truths that discussion may help prevent. This is why many enjoy true crime documentaries: to understand the sorrow and pain, grasp the why and the how, and develop self-awareness. This allows authors to consider writing what they know, sometimes drawing from the news. For example, the events of the disappearance and death of Laci Peterson in 2002 resemble the events within Gillian Flynn’s Gone Girl. Both stories involve the disappearance of a pregnant woman while her husband receives attention from the public and police. The novel demonstrates how crime can be a lesson, not simply a piece of enjoyment.
However, this is not the sole reason for the popularity behind the genre. Many enjoy mystery because solving the case satisfies their curiosities and need for entertainment. The digital age has amplified this entertainment by allowing readers to find new ways of accessing the genre, creating a surge in popularity. Through eBooks and audiobooks, readers can engage with the stories wherever they are. Within Canada, mystery and thriller novels remain well-admired among eBook readers, with 48% reporting that they read the genre in 2025, making it the most-read adult fiction category within this format.
The Detective is often the soul of a crime novel, as its plot rests upon their shoulders. Readers gravitate towards characters written as complex individuals with flawed characteristics. Their realism and duality is what makes them popular. Take Sherlock Holmes for example. Even though his first appearance was in 1887, audiences have not forgotten him. Instead, he is the most frequently portrayed literary human character in television and film. His personality resides on not only being a ‘know-it-all,’ but also having his own troubles as he struggles with drug abuse. Doyle has created a character who is not invincible, thus being someone readers can relate to. After all, that is the kind of character many crave when reading: someone who matches themselves, who they can see themselves in, helping diminish their loneliness.
Another popular detective is Hercule Poirot, a Belgian private detective residing in England, who first appeared in Agatha Christie’s The Mysterious Affair at Styles in 1920. Although different from Holmes, his acclaim has not wavered. Readers are invested in him due to his charming personality. Christie writes Poirot as intelligent, yet lacking a proper vocabulary at times. He often misuses common idioms or quotes, highlighting his flaws. Readers are not drawn to perfect characters, but ones who make the common mistakes, thus retaining the audience’s interests in Holmes and Poirot.
By creating a well-defined idea of what a crime novel entails, authors of the 21st century are able to expand upon that idea and re-imagine it into new stories that readers are invited to examine. The grip crime literature has upon its audience is what keeps it alive. It is why the genre remains viable decades later and the lessons rooted within the true horrifying nature of the world today are why it needs to remain discussed.
