S2·E16 The Evil of Adelaide Winters

Near the end of World War II, a phony medium named Adelaide Winters cheats grieving families of soldiers killed in battle by pretending to communicate with ghosts. When she meets a wealthy widower named Edward Porter and finds out that his son was killed in battle, she insists that he join her seance. Edward reluctantly joins and begins to believe in Adelaide powers. Eventually, he proposes marriage to her so that the two of them can be with his son. Adelaide accepts the proposal but the honeymoon doesn't go as planned.
