Episode: Four. Roger develops his photos of the hillside copse - and they seem to reveal a strange silhouetted figure. Meanwhile, Huw Halfbacon is convinced that the three youngsters have become entangled into a re-enactment of old events which previously resulted in tragedy. Nancy also reveals how, had circumstances been different, she would have inherited the house - had her relationship with its former owner (Alison's father's uncle) been allowed to continue.
