I will be the head detective, and I will teach you guys how to solve crimes. I will show you how to use my magnifying glass and Decod-R ring. Then I will show you how to dust for fingerprints.
Good detectives learn lots of things from fingerprints.
That is because they are like snowflakes. No two are the same. You can make fingerprints show up by sprinkling powder over them. Then you just have to find out who they belong to. Also, you should look at footprints.
