原文
The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamonds from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plan arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened the parcel. To their surprise, the precious parcel was full of stones and sand!

由于飞机晚点，所以侦探在飞机场等了一上午。他们在这里等待从南非寄过来的一个装着钻石的贵重包裹。在不久之前，有人告诉警察，有盗贼想偷这笔钻石。当飞机到达之后，一部分侦探在候机大厅待命，一部分等待在飞机坪旁。由其中的两个人从飞机上拿下包裹进了海关。这时他们安排两个在门外守着，另外两个打开了盒子。让人意想不到的事情发生了，这个珍贵的包裹中满是石头和沙子。
