The city is ready for its annual dance festival, but a problem has appeared. The choreography notes for the traditional dance are missing. Without these notes, the dancers cannot practice the steps correctly.

I talked to the main dancer, Anna. She said, "I last saw the notes in the dance room yesterday morning. After that, they were gone." The dance teacher, Mr. Lee, also said, "We always keep these notes safe, but now, they are not where we usually keep them."

I asked the cleaning staff if they found anything unusual. One cleaner said, "I saw a new person near the dance room yesterday afternoon. They were holding some papers." This is an important clue.

Finally, I met the new helper, Tom. He explained, "I took the papers by mistake to copy them, but I planned to return them today." He gave back the notes to the organizers.

Thanks to quick investigation and talking to many people, the problem was solved. The dance festival will go ahead with the traditional routine. This event shows how tradition and teamwork help the community.
