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) 低頭看著他的黑色偵探的包。 他瘦削的手指從放大鏡、夏洛克·福爾摩斯的帽子和偵探的筆記本上滑過。 如果這些還不夠，他還有假護照、粘胡子和解碼器戒指。 斯坦利合上包，自信地點點頭。 他受夠了這份工作。 羅德先生的聲音仍然從公共汽車的頭頂揚聲器中傳出，“……這是阿納薩齊人最大的謎團。為什么這些美洲原住民突然離開家園?是戰爭、疾病還是干旱?科學家們仍然沒有” 沒問題。30 分鐘后，在梅薩維德國家公園，我們將有機會環顧四周?！?“參觀完崖宮后，我們就去參觀博物館。我希望你表現得像個成熟的四年級學生。請聽公園管理員的指示?！?
