Next to die is Dr. Drossos, proving that the advice of modern science does not guarantee victory over the disease. Suspicion returns to Thea, and Kyra harasses her with taunts and threats. Pherides vows that he will kill Thea if evidence appears that she is "vorvolaka". Fearing for Thea's life, Oliver plans to escape with her, but Pherides destroys the only boat. Mrs. St. Aubyn falls into a cataleptic trance; everyone (except Thea) believes her to be dead, and they entomb her. Oliver and Aubrecht believe the cause to be plague but Kyra and Pherides believe it to be the doing of the "vorvolaka". Oliver advises Thea to stay away from Pherides.
