"Richard Oort, upper-class concert pianist turned Albuquerque cop, adds a new career as a paladin wielding a sword that embodies reason and order. Recruited by Kenntnis, a wealthy technology entrepreneur, after rescuing a sorceress in distress, Richard learns that Kenntnis is the Serpent, and Prometheus, and Lucifer. Richard is his latest weapon in the eons-old battle against the Old Ones, who feed on emotions stirred by religious beliefs."
