Learn about securing a crime scene, and gathering and documenting evidence, including fingerprints, footprints, and tire tracks. After you have gathered evidence, such as hair and fibres, counterfeit currency, and soil samples, you will head back to the lab to learn about analysing it. Finally, you can try your hand at deciphering codes, writing messages with invisible ink, and communicating with secret symbols. As your detective skills develop, you can use them to solve the mock crime presented in the manual. Age 8+
