Trance by Appointment is the story of Jean, an otherwise ordinary working-class London girl. But Jean has what her mother calls “the Sight.” She sees what no one else can: the future. At first, under the patient guidance of Madame Eva, she learns to control this talent and begins to work as a fortune-teller.But once Jean falls under the influence of Norman, an unscrupulous astrologer, she is exploited as a money-making machine, driven relentlessly to perform seances for exclusive clients. Norman treats Jean as a dumb animal with a uniquely saleable skill and subjects her to physical and emotional abuse in quest of profits. Telling Jean’s story through her eyes and words, Gertrude Trevelyan’s demonstrates an uncanny insight into the gift and curse of an exceptional power.
