Придумайте детективную историю на английском языке

Once, in my school, and it was Grade 5, something happened, but my friend and I did not understand exactly what it was, but we learned that the school guard was involved in this. Armed with walkie-talkies, we went to find out exactly what happened. We divided the school into sectors, interrogated witnesses, but found nothing for a year. It turned out that the teacher told me a week later, the thieves wanted to get into the school, but the guard prevented them. After this incident, we decided to patrol the school. At recess we walked around the whole school by sector, it was interesting because the teachers did not allow us to leave the class. But we did not find such thieves.
