绘本简介

Stanley DeCapers peered down into his black detective's bag. His skinny fingers shuffled past the magnifying glass, Sherlock Holmes hat, and detective's notebook. If those weren't enough, he also had the fake passport, stick-on mustache,and decoder ring. Stanley closed his bag and nodded confidently. He had enough for this job.

Mr. Rhodes's voice still blared from the bus's overhead speakers,"... that is the biggest mystery of the Anasazi people. Why did these Native Americans suddenly leave their homes? Was it war, or disease, or drought? Scientists still aren't sure. In 30 minutes, at Mesa Verde National Park, we'll have the chance to look around ourselves."

"After our tour of Cliff Palace, we'll visit the museum. I want you to behave like mature fourth graders. Please follow the park ranger's instructions."

斯坦利·德卡珀斯 (Stanley DeCapers) 低头看着他的黑色侦探的包。 他瘦削的手指从放大镜、夏洛克·福尔摩斯的帽子和侦探的笔记本上滑过。 如果这些还不够，他还有假护照、粘胡子和解码器戒指。 斯坦利合上包，自信地点点头。 他受够了这份工作。 罗德先生的声音仍然从公共汽车的头顶扬声器中传出，“……这是阿纳萨齐人最大的谜团。为什么这些美洲原住民突然离开家园?是战争、疾病还是干旱?科学家们仍然没有” 没问题。30 分钟后，在梅萨维德国家公园，我们将有机会环顾四周。” “参观完崖宫后，我们就去参观博物馆。我希望你表现得像个成熟的四年级学生。请听公园管理员的指示。”
