Quick Work

     Ted Robinson has been worried all the week. Last Tuesday he

received a letter from the local police station. In the letter he was asked

to call at the station. Ted wondered why he was wanted by the police,

but he went to the station yesterday and he is not worried any more.

     At the station, he was told by a smiling policeman that his bicycle

had been found. Five days ago, the policeman told him, the bicycle was

picked up in a small village four hundred miles away. It is now being sent to his home by train.
