discuss how the curse has been lifted and the pyncheon family is now at peace

As the new heir to the Pyncheon fortune with Phoebe, Holgrave thus will receive the land that his ancestors rightly deserved. By finding the deed and map, the remaining Pyncheons end the family tradition of seeking this legendary fortune for sinister ends.
