도윤과(와) 나무집 카이사르 암호
6–8세
오래된 참나무 위 나무집에서 꼬불꼬불한 글씨로 가득한 수상한 쪽지가 발견돼요. 도윤은(는) 빙글빙글 도는 암호 원판을 만들어 암호를 풀고, 시간이 다 되기 전에 탐험대의 비밀 모임에 도착하려 해요.
도윤 loved secrets almost as much as he loved climbing trees. So when Pip trotted up with a scrap of paper clenched in its jaws, 도윤's heart thumped. The paper was covered in strange wavy squiggles that made no sense at all. "What is THIS?" he whispered.
"Let me see!" said Nessa, sliding down from the treehouse window. She pushed up her round glasses and studied the wavy marks. "This isn't nonsense," she said slowly. "Somebody drew this on PURPOSE. It's a secret code."
"A code for what?" 도윤 asked. Nessa tapped the paper. "Look here—it's about the troop's meeting spot! If we crack it, we'll know exactly where everyone is gathering today." 도윤's eyes lit up. A puzzle AND a mission? He was ready.
