Exploring the Mystery Genre in Literature
The excerpts presented appear to be sourced from different works of literary fiction, especially those related to the mystery or suspense genres. The dialogue involving Professor Plum considering the killer being outside is typical of mystery narratives that involve the process of deduction and suspense. Similarly, other passages that involve characters contemplating the presence of unknown entities, debating over the guilt or innocence of individuals, and discussing potential supernatural elements are common themes in mystery and suspense literature. These excerpts may be from plays, novels, or short stories where the characters are involved in discerning the truth behind certain events or crimes. The focus on careful examination, hidden motives, and unexpected outcomes is characteristic of this literary genre.
Subjects like the unexpected entrance of assassins, Goodman Brown's fear of the devil, and the crafty murder method described in the dialogue reflect the intrigue associated with the genre. The question from the student discussing Professor Plum's dialogue sets the stage for suspense as it implies the possibility of danger lurking outside, a common theme in detective fiction.
