The most mysterious teacher

When it was my turn, and I was about to put my homework notebook on the teacher’s desk, I suddenly noticed in the stack of papers that belonged to Mr. Peterson, there were notices about the missing three teenagers. These teenagers disappeared a year ago and have already been found, but still: where did he get these ads? There were some maps not far from the ads, but I didn’t have time to see them. I quickly handed in my notebook and returned to my seat. Mr. Peterson did his homework and the bell rang. All the classmates ran out of the classroom, leaving only me, Jane, and Emma. Soon, Mr. Peterson took a stack of papers and left the classroom. Emma came up to Jane and me: — Did you also not like the new drawing teacher? — He’s kind of normal, — Jane replied. — That’s easy for you to say, because you’re a C student, and I’ve been pulling for a good one all year! — You shouldn’t have been on the phone! —Oh, right! — Emma was angry. — Girls, stop swearing! — I tried to intervene. But my friends didn’t listen to me: — You didn’t do your homework yourself! — I just forgot! — That’s not true! — Girls! My friends turned to look at me. — What? — Jane asked. — Do you remember the teenagers who disappeared last spring? — Yes, but what is the connection between the fact that Jane was too lazy to do her homework and the missing teenagers? — Emma asked me. — Hey, actually, I just forgot! — And that’s not it! I rolled my eyes. Girlfriends are not fixable! — That’s not what I meant. When I handed in the notebook, I noticed that there were flyers about missing teenagers and some maps on Mr. Peterson’s desk, — I said. — What kind of cards? — Emma asked, interested. — I didn’t get a chance to see. — It’s a pity, — Jane replied. — What makes you think these are Mr. Peterson’s papers? — Emma asked again. — Because when we had another drawing teacher, these papers did not exist. Moreover, when the lesson ended, Mr. Peterson took them with him. — I replied. — That’s weird, — Emma said. — But why would Mr. Peterson take these flyers with him to class? It’s illogical, isn’t it? — asked Jane. — On the contrary, it is very logical. If he needs these papers and doesn’t want to lose them, he’ll carry them with him, — Emma replied. — But why bring them to school? And even more so, why does he need these leaflets? — Jane asked again. — I don’t know, — Emma replied. — Maybe he’s hiding something? — Jane suggested. — It’s possible, — Emma agreed. — Let’s find out what exactly? — I suggested. The girls looked at me in surprise. — Come on! — Jane immediately agreed. Emma was skeptical: — But it can be dangerous! — Oh, don’t worry. If you’re scared, say so, — Jane egged Emma on. — I’m not a coward! I agree, — Emma replied. — Hurrah! We’ll find out Mr. Peterson’s secret soon! — Jane was delighted.
