Can you name some characteristics of 'the first full length detective novel'?

If we consider 'The Moonstone' as the first, it has a central mystery, like the theft of the precious Moonstone. It also has a detective character, Sergeant Cuff, who uses his wits to investigate.

The first full - length detective novel is often considered to be 'The Murders in the Rue Morgue' by Edgar Allan Poe. It established many of the conventions that are still used in detective stories today, such as the brilliant detective using deductive reasoning to solve a seemingly impossible crime.

Well, 'The Moonstone' is often regarded as the first full length detective novel. This novel introduced many concepts that are now staples in detective fiction. It has a complex plot that involves the disappearance of a valuable diamond, the Moonstone. There are different characters, each with their own motives and secrets, which makes it a great detective story.

One strong candidate is 'The Murders in the Rue Morgue' by Edgar Allan Poe.

Well, if we take Sherlock Holmes as an example, one characteristic is extreme intelligence. Holmes can observe the tiniest details and make astonishing deductions from them. Another is his eccentricity. He has his own odd habits and ways of thinking that set him apart from ordinary people. Also, his strong sense of justice drives him to solve cases.

In the first Sherlock novel 'A Study in Scarlet', it has a complex mystery. There are two intertwined plotlines.

One characteristic could be its length. Since it was the first of its kind, it likely had a certain amount of length to fully develop its story. Also, it probably had some form of character development, even if it was rudimentary compared to modern novels. For example, if we consider 'The Tale of Genji', the main character Genji has a long journey through life, and we see his growth and changes.

Typically, the first noir novels had complex and morally ambiguous characters. They weren't simply good or bad. For example, in 'The Postman Always Rings Twice', the characters' actions are driven by lust and greed, blurring the lines between right and wrong.

If we consider 'The Picture of Dorian Gray' as a candidate for the first gay novel, one characteristic is the subtlety in portraying homoerotic relationships. It wasn't overt, as the society of Wilde's time didn't allow for blatant homosexuality in literature. So, it was more about the undercurrents of attraction between characters like Dorian and Lord Henry.

The first spy novels often had a focus on secrecy and subterfuge. For example, in 'The Spy' by James Fenimore Cooper, the main character had to hide his true identity and motives while gathering information.
