Novelist and professor Valerie Martin. She's been called the "heir apparent to Edgar Allen Poe." She's taken the Robert Louis Stevenson classic tale of Dr. Jekyll and Mr. Hyde and given it a new twist. Her new historical novel, "Mary Reilly," tells the story of Jekyll's descent into madness from the point of view of Mary, a Victorian maid in Jekyll's household. Mary escaped the squalor and brutality of the slums to become a servant. As she becomes Jekyll's confidant she's once again drawn into the underworld she sought to escape.
