Cyril was a hungry little worm. He lived in a library under a loose floorboard. He nibbled at all the corners of his much loved books. One day he heard the head librarian speaking on the telephone and saying that they would have to fumigate; books were being destroyed. Cyril became very distressed and knew he would need to vacate the library immediately. His life was in danger. Sadly, he would have to find another home. He wrote a letter to his friend Wriggles asking for his help and advice. Does Wriggles come to his aid, what happens along the way and where will his new home be?
