Arriving in New York, Mark goes straight to Rose's building, where he meets Carol, the concierge, and some of the residents, including a nurse who cares for elderly Professor Arnold, a wheelchair-bound mute. Mark encounters the sickly Countess Elise De Longvalle Adler, who tells him that Rose has disappeared. After the two find blood on the carpet outside Rose's room, Mark follows the stains. Inhaling a strange odour, he becomes ill and falls unconscious. Elise sees a black-robed figure dragging Mark away, but the figure stops and gives chase to Elise. The figure eventually finds her swarmed with rabid cats in a room and stabs her to death. Mark staggers to the apartment building's lobby where Carol and the nurse put him to bed.
