Detectives around the world
Detectives help solve mysteries and crimes. In the past, they worked with notebooks and magnifying glasses. Today, they use computers, cameras, and science to find clues. Detectives didn’t always have modern tools, but they still solved cases using logic and questions.
In England, detectives like Sherlock Holmes became famous for their clever thinking. Holmes asked questions, looked at small details, and found answers that others missed. He didn’t use machines—just his brain.
In South Korea, detectives often work in teams. They share ideas and follow evidence together. They don’t work alone. This teamwork helps them solve cases faster.
In Mexico, detectives sometimes helped with missing items or people. They talked to families and searched neighbourhoods. They didn’t stop until they found answers.
Detectives in every country use different methods, but they all try to find the truth. They ask questions, follow clues, and help people.
