The Definition of Cozy Mystery

Cozy mysteries, also known as “cozies,” are a subgenre of crime fiction that typically feature amateur detectives solving murders in small, idyllic communities.

Cozies are characterized by their focus on the personal relationships and daily lives of the characters, rather than graphic violence or explicit descriptions of crime scenes. They often take place in quaint, picturesque settings such as small towns or villages and include elements of humor, romance and a sense of community.

The detective is often an amateur and not a professional, and the crimes are often committed by someone known to the community, often with a closed circle of suspects. The emphasis is on the puzzle-solving aspect of the plot rather than the violence or gore commonly found in other crime fiction.

In this regard, cozies differ from hardboiled fiction, where the storyline typically centers around more violence and explicit sexuality.

Some of the best known examples of the genre are Agatha Christie‘s Miss Marple series (featuring the amateur detective Miss Jane Marple, a spinster who solves crimes in the fictional village of St. Mary Mead), Dorothy L. SayersLord Peter Wimsey series (featuring the amateur detective Lord Peter Wimsey, an aristocrat who solves crimes in 1920s England), and Martin EdwardsLake District series (featuring the amateur detective Hannah Scarlett, a solicitor who solves crimes in England’s Lake District.)

What makes a good cozy mystery story

Here are a few key elements that make a good cozy mystery story.

A charming setting with a strong sense of community is a must. A puzzling mystery with a lighthearted tone make a cozy mystery a comfort to read rather than a suspenseful story to pump the adrenaline.

Lastly, a focus on everyday life (i.e. characters doing day-to-day mundane activities) with an amateur sleuth as the main protagonist who’s typically smart (despite their amateurism), resourceful, and relatable, someone the reader can root for and learn from.
