It is said that if a girl looks into a mirror on the night of Halloween and sees a man standing behind her, that will be the one she will marry. But the face that Jonathan Blake's neighbour saw behind her was that of a man next in line to be murdered! She ran to her neighbour for help. Blake, ever ready to assist a pretty girl, came just to reassure her - but he stayed almost long enough to be next on the murder list.
