Which of these is not a cozy mystery?

Cozy mysteries, also referred to as "cozies", are a subgenre of crime fiction in which sex and violence are downplayed or treated humorously, and the crime and detection take place in a small, socially intimate community. Cozies thus stand in contrast to hardboiled fiction, which features violence and sexuality more explicitly and centrally to the plot. The term "cozy" was first coined in the late 20th century when various writers produced work in an attempt to re-create the Golden Age of Detective Fiction.

"A Scandal in Bohemia" is not a cozy mystery. It is the first short story, and the third overall work, featuring Arthur Conan Doyle's fictional detective Sherlock Holmes. It is the first of the 56 Holmes short stories written by Doyle and the first of 38 Sherlock Holmes works illustrated by Sidney Paget. The story is notable for introducing the character of Irene Adler, who is one of the most notable female characters in the Sherlock Holmes series, despite appearing in only one story. Doyle ranked "A Scandal in Bohemia" fifth in the list of his twelve favourite Holmes stories.
