Brideshead Revisited
Charles's own wife has been unfaithful, so he plans to divorce her so that he and Julia can marry. However, Julia decides for religious reasons that it would not be right for her to marry Charles. As Lord Marchmain lay dying, he had received the sacrament of Extreme Unction.  This act had also influenced Charles, who had been "in search of love in those days" when he first met Sebastian, "that low door in the wall...which opened on an enclosed and enchanted garden,", an important metaphor in the book.
