I saw a synopsis of this book and forgot to add it to my want to read list. The book was about a couple who buy a house on a cliff or near a bridge or somewhere where people commit suicide often. The husband helps talk people out of it and saves many lives. One day the wife sees someone go over the edge and suspects her husband may have pushed her.
