Flower, A. What exactly is a cozy mystery?, 2018 via Publishers weekly website, viewed May 7, 2019 (An amateur sleuth, an unsuspecting victim, a quirky supporting cast, and trail of clues and red herrings are the main ingredients of a cozy mystery. The term "cozy" was coined in the late 20th century...In a cozy, the reader has the opportunity to solve the murder right along with the main character. As such, the readers believe they can solve the crime, too. The very best cozies are the ones in which the reader thinks she has solved the crime, finds out that she is wrong at the end of the book, but feels satisfied with the just conclusion because it is a surprise, but more importantly because the plot makes sense) https://www.publishersweekly.com/pw/by-topic/industry-news/tip-sheet/article/76834-the-enduring-appeal-of-the-cozy-mystery.html
