High School Mission

Schools are usually safe places, right? We go there, or we send our kids, to learn new things, to educate ourselves for the future. Schools don't need to be places where we should feel endangered by something or unsafe. But unfortunately, bad things happen everywhere. Criminals visit even schools, and some of them even go to those schools.
The two detectives, Diane and Tyler, come to the high school in their city. There has been a robbery in the school, but no one knows who are the thieves. The detectives are on duty, ready to do whatever it takes to find the thieves. The thieves have stolen some valuable objects from the school, but also the money from the school cash register. Who could be in charge of such a crime? Is it some street thief or maybe someone that goes to that school?
Let's check out the whole situation together with Diane and Tyler, and find out if we can help them somehow. We will search the whole school looking for some pieces of evidence, and we hope that the thieves will be caught as soon as possible.
