Books with title The little fat policeman

The Little Fat Policeman is very busy. He directs all the whizzing traffic. He stopped a car that was going too fast, and when the lady driver explained that she was singing a very fast song and forgot, he replied, "Sing a slow song next time, and don't forget or I'll have to give you a ticket...." We next see him as he investigates a burglary, which has a surprise ending. Finally, the Little Fat Policeman is a life saver, as he rescues a man who encountered problems when swimming in the ocean. Quite the busy man!
