Gentleman detective

The gentleman detective is a type of fictional character. He (or she) has long been a staple of crime fiction, particularly in detective novels and short stories set in the United Kingdom in the Golden Age. While not necessarily aristocracy, the heroes of these adventures are often members of the British gentry or gentlemen by conduct. They are sometimes contrasted with professional police force detectives from the working classes.^[1]

Gentleman detectives include amateurs, private detectives and professional policemen. They are always well educated, frequently have unusual or eccentric hobbies, and are commonly found in their natural environment, an English country house. This archetype of British detective contrasts with the more "hardboiled" counterpart in American crime fiction.
