What Is A Thriller?

Published February 13, 2020 by Gail Daley Writer & Artist

The first question asked when a writer sends a manuscript to an agent, a publisher or a self publishing site, is “What genre is it?” Several Years ago, I wrote a blog defining the many Art Genres. This year, I decided to try the same with writing. I searched the internet and pulled up most of these definitions from Wikipedia, and various other internet sources who defined writing genre. It is by no means a comprehensive list, but it might help my fellow writers when asked by a publisher to define the genre of the book they have just written. There is an enormous amount of information about book genres, so I will be presenting these blogs genre by genre over the next few weeks. I limited myself to fiction. I may do a similar chart for non-fiction later though. I got the idea for the chart from a Facebook post, but I made some changes and additions to what was there. Please feel free to share or add to it.

Thriller is a broad genre having numerous subgenres FYI: it is not the same genre as a mystery. Thrillers are characterized and defined by the mood of fear and suspense they elicit, giving viewers heightened feelings of excitement, surprise and anxiety. A thriller generally has a more villain driven plot than adventure. This list is my no means all inclusive.

Eco Thriller:Eco thrillers are normally set around a threat (natural or man-made) to the environment, and combine action, adventure with maybe a touch of mystery. They are fast-paced and usually laced with science. The lead character must find a way to negate the threat.

Supernatural Thriller: Supernatural fiction or supernaturalist fiction involves plot devices or themes that contradict Ideas and assumptions commonplace in the natural world. It is very closely aligned with Horror though usually in a more inhibited fashion. This genre brings in an otherworldly element, Often the hero and/or villain has (or at least claims) some psychic ability.

Historical Thriller: This genrediffers from other thrillers in that is set in the past, usually prior to 1960.It may also contain elements of espionage, military or other genres but should not be confused with political/conspiracy thrillers which occur in a more contemporary setting.

Medical/Psychological Thrillers: I have lumped these to together because they draw from similar backgrounds. In Medical Thrillers, a doctor’s life is often threatened (because they helped a certain patient), or a mysterious (usually artificial) disease has broken out. Robin Cook and Tess Gerritsen are leaders in this subgenre. Sandra Wilkenson’s novel Death On Call is an early example. (sometimes the authors are doctors themselves.) Psychological subgenre tales build up slowly, with ever-increasing doubt and tension, until some explicit action/violence takes place, usually at the finale.

Political/Conspiracy Thriller:This genre is very similar in some ways to the Environmental Thriller. Usually the hero or heroine confronts a large, well organized company, government dept., or group. The threat posed by this group is only perceived by the protagonist. A great deal of the plot revolves around a single individual defeating the above groups while encountering disbelief from everyone around him/her. Perplexing forces pull strings in the life of the lead character — if not throughout the world. Usually the hero becomes a threat to the conspirators, and must escape their wrath. Often these stories depict the aberrations caused by secrecy, and the corrupting influence of power.

Espionage or Spy Thriller: As a genre, spy fiction is thematically related to the adventure novel and involves espionage as an important background or plot device. It emerged in the early twentieth century, inspired by rivalries and intrigues between the major powers, and the establishment of modern intelligence agencies. The genre was given new impetus by the increase of fascism and communism in the lead-up to World War II. It continued to develop during the Cold War, and received a fresh impetus from the emergence of rogue states like ISIS, international criminal organizations, global terrorist networks, maritime piracy and technological sabotage as convincing threats to Western societies.

Techno Thriller:A techno-thriller is a hybrid genre drawing plot elements from science fiction, thrillers, spy fiction, action, and war novels. They include a lopsided amount of technical details on their subject matter; only hard science fiction tends towards a comparable level of supporting detail on the technical side. The inner workings of technology and the mechanics of various practices (espionage, martial arts, politics) are thoroughly explored, and the plot often turns on the of that exploration.

Military Thriller: the focus of this genre is on the development of the crisis, and the detailing of the military action. an aggressive move by the Bad Guys forces the Good to wage large-scale combat to stop them. This can also be found on a smaller scale with many novels set in WWII or prior. However, these are cross genre novels coinciding with Historical thrillers.

Legal Thriller:the plot usually is centered around courtroom action, with a lawyer as the protagonist. This is not to be confused with a Courtroom Drama. In a courtroom drama, the reader often doesn’t know who the villain is until the climax of the story. In a legal thriller, the reader generally knows who the bad guy is from the beginning and the action focuses on whether justice is served.
