'My Daddy! My Daddy!' has become one of the most famous tearjerking lines.

Bobby's cry as her father's figure appears through the mist of the steam train in this story of a family's stalwart struggle to keep calm and carry on when forced by the wrongful arrest of their father on spying charges to move from their idyllic life to a rundown cottage by a railway line has jerked the tears of generations of readers (and, in latter years, filmgoers and theatre audiences) and has become one of the greatest happy endings of them all in this superb children's classic novel by Edith Nesbit.
