Imagine being 9 years old and learning that someone wants to kill your family. That's what happened to Cylin Busby when she was growing up in Falmouth, Massachusetts. Cylin's father, John, was a cop who refused to be intimidated -- even by a thug suspected of one murder and two disappearances. But one summer night in 1979, John Busby was ambushed and gunned down. With the shooter at large, his young family had to run for their lives. Cylin, now grown up, tells a story of revenge and the long-awaited justice that no one could predict.
