A woman, having escaped from the house, tells the manservant that she is scarred for life. She threatens to go to the police and tell them about this madman.

A boy sees the form of his dead father return as a horribly disfigured and rotten-faced man.

Blindly he stumbles out of the house and into the darkness.
