Shore hears of an apparition that haunts the hallways at night and seems to portend death. Flashlight in hand, she goes off in search of the "Black Nun."
A lonely man with punctilious habits listens to a tape cassette of ambient barroom sounds, which include the hushed tones of two men plotting to kill him; but when a policeman listens, all the sounds are there except those of the two men.
Shore learns that Sister Miriam had recently inherited a fortune. While one nun warns Shore to get out while she can, another is all too eager to confide her suspicions.
Shore finds an underground passageway from the crypt to the tower and discovers a link between the dead nun and a missing schoolgirl. Unfortunately, the Black Nun is also on the hunt.
The police disbelieve Skipling's story of the man bleeding from the eyes. Later, Skipling receives an unwanted visit from a doctor and a welcome visit from his "befriender".
