Amazon.com description: Product Description: The Sacred Fount is a novel by Henry James, first published in 1901. This strange, often baffling book concerns an unnamed narrator who attempts to discover the truth about the love lives of his fellow-guests at a weekend party in the English countryside. He spurns the ”detective and keyhole” methods as ignoble, and instead tries to decipher these relationships purely from the behavior and appearance of each guest. He expends huge resources of energy and ingenuity on his theories, much to the bemusement of some people at the party. As he waits for the train to take him to a weekend party in the country, the narrator notices that Gilbert Long seems much more assured and lively than before. He also sees Mrs. Brissenden (nicknamed ”Mrs. Briss”) as much younger-looking than her husband, though she’s actually ten years older. The narrator begins to theorize that Long and Mrs. Briss are getting their vitality, vampire-like, from the ”sacred fount” of their sexual partners’ energy. At first the narrator theorizes that the source of Long’s newfound assurance and intelligence is a certain Lady John.
