A ghostly figure arrives at the Legacy house and tells Derek that it has his sister, Ingrid, and will exchange her for The Blood Chalice. The cHalice is an Incan artifact that is said to bestow immortality to whomever uses it to drink the blood of a still beating heart taken from a sacrifice. Derek visits the church where Ingrid is a nun and finds out that the woman who kidnapped her wore a Legacy Prefect ring. When Sloane arrives from London the number of women prefects that the Legacy have is revealed and the main suspect is soon deduced.

Can Sloane and Derek find a way to find out where Ingrid is being held before she is killed and without giving away the Chalice?
