How many kinds of Detectives are there?

There are several types of detectives, primarily categorized into private detectives, public detectives, and specialized detectives. Private detectives work independently or for agencies, often handling cases like infidelity or fraud. Public detectives, typically part of law enforcement agencies, investigate crimes and enforce laws. Specialized detectives may focus on specific areas such as cybercrime, homicide, or narcotics, using expertise in those fields to solve cases.
