- Plot: In 1903, Dr. Bailey meets a very strange woman on a train, then hears that she has died under mysterious circumstances. Through a friend, he becomes acquainted with the Bederaux family, all of whom seem to be neurotic and secretive; but the beauty of Alida Bederaux draws him into their circle...deeper than he'd planned. Who's in danger from whom? Who's crazy? Who can fathom the obscure motivations?
