Hetty Wainthropp Investigates - Season 2 Episode 4 : The Astral Plane 1998

Hetty gets mystical as she investigates Maurika Rome, a spiritualist suspected of using séances and blackmail to prey on the savings of the recently widowed. When Hetty goes undercover and invents a late husband she wishes to contact, she begins to wonder if Mrs. Rome isn't the real thing - until a woman claiming to be her "late husband's" illegitimate daughter shows up demanding money. Geoffrey's secret romance with Rome's daughter, Sara, threatens to undermine Hetty's carefully laid trap and nearly causes him to quit the agency.
