In the second episode of the four-part story "The Mask of Mandragora," the Doctor (
Tom Baker) and Sarah (Elisabeth Sladen) find themselves trapped in the Italian village of San Martino in the 15th century. The village is held in the grip of terror by an ancient religious coven called the Brotherhood of Demnos -- which, in turn, is under the control of the Mandragora Helix, an entity been on conquering the world. Norman Jones is cast as Hieronymus, leader of the Brotherhood. Originally telecast on September 11, 1976, "The Mask of Mandragora, Episode 2" was written by Terrance Dicks. ~ Hal Erickson, All Movie Guide
