The Astral Plane

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.
