"The Bluff" made quite an impression on me when I heard it (back in 1980). Larry Haines was a consistently excellent performer, and Henry Slesar's script harkens back to the classic pulp magazines. The one weakness in the script is the "showdown" ... I expected more with the darkened house and the blind man's deadly game of hide and seek, sounds of footsteps on hardwood floors, etc. Overall, though, great script.
