Longstreet was the pilot for one of the better "gimmick" detective series of the 1970s. The title role of Michael Longstreet is played by James Franciscus. Longstreet is a New Orleans insurance investigator who has been permanently blinded in a mysterious bombing which has killed his wife. As he recuperates and trains himself to function in a sighted world, Longstreet determines to avenge his wife's death by continuing his detective work and tracking down his assailant. Longstreet's closest companions are his female braille instructor (Martine Beswick in the pilot, Marliyn Mason in the series) and Pax, his seeing-eye dog. Longstreet was created and produced by Stirling Silliphant of In the Heat of the Night and Naked City fame.
