Which of these authors is known for their contributions to the genre of detective fiction?

Agatha Christie is renowned for her significant contributions to the genre of detective fiction, making her one of the most celebrated mystery writers of all time. Her works, which include iconic characters like Hercule Poirot and Miss Marple, are celebrated for their intricate plots, clever clues, and surprising twists. Christie mastered the art of crafting engaging detective stories that have captivated readers for generations, establishing various conventions of the genre, such as the "locked room" mystery and the cozy mystery format.

While Jane Austen, Virginia Woolf, and Charles Dickens are each important literary figures in their own right, their primary works do not focus on detective fiction. Austen's novels revolve around themes of social commentary and romance, Woolf is known for her modernist techniques and exploration of consciousness, and Dickens often incorporated elements of social critique and character-driven narratives, rather than the structured mystery format that defines Christie's writing.
