The "soul-converting instrument" is the fantasy of breaking through the boundaries of life and death by the technological fanaticism of the British Industrial Revolution era. It is also a symbol of the ultimate exploitation of the lives of the poor by the rich in the solidification of classes.
Intention: the value, dignity and meaning of life, the conflict between technology and ethics, the complexity and indifference of human nature, the coldness of the powerful and their manipulation of the disadvantaged, and the brilliance of women's friendship in adversity.
