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
plane 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 presious parcel was full of
stones and sand!
