Agatha Christie, the mystery novelist, loved playing frightening games in childhood. Here she tries to explain why:
“Why did I like being frightened? What instinctive need is satisfied by terror? Why, indeed, do children like stories about bears, wolves and witches? Is it because something rebels in one against the life that is too safe? Is a certain amount of danger in life a need of human beings? Is much of the juvenile delinquency nowadays attributable to the fact of too much security? Do you instinctively need something to combat, to overcome — to, as it were, prove yourself? Take away the wolf from the story of Red Riding Hood and would any child enjoy it? However, like most things in life, you want to be frightened a little — but not too much!”
Agatha Christie in Agatha Christie: An Autobiography (Ballantine, 1978).
