Detective Fiction

Detective fiction is a type of story that usually includes a crime, most often a murder or theft, and a detective who works to solve it. The detective is usually the main character, and the story focuses on how they collect evidence, question suspects, and reveal the truth. This genre often keeps readers guessing with suspense, red herrings, and a final twist that feels both surprising and logical.

Doyle’s Use of Detective Fiction

Arthur Conan Doyle applies these features in The Sign of Four through the character of Sherlock Holmes. Holmes represents the classic detective figure with sharp observation skills, logical reasoning, and a calm approach to solving mysteries.

The story also follows many elements of the genre, such as the mysterious crime, multiple suspects, hidden motives, and an ending that resolves the puzzle in a clever and unexpected way.

Final Thoughts

The Sign of Four shows how detective stories can be more than just about solving crimes. Doyle uses the genre to explore human motives, greed, loyalty, and justice, making the mystery both exciting and meaningful for readers.
