Just Dial a Number Author:Edith Maxwell It was only a prank call dialed at random -- a joke played by four teenagers. But what happened afterward plunged them into a nightmare, and by the next morning, two people were dead. Cathy, Paul, Todd and DeeDee had to live with their guilt -- and the terror of being found out!
This book is an oldie but a goodie. I think I read it over ten times when I was a teenager. An innocent prank pulled by four friends leads to the death of a classmate's parents. It is definitely worth reading.
