MISSION IMPOSSIBLE 521: A Ghost Story (2/27/1971)
Howard Bainbridge, a chemical warfare expert who defected to East, was contaminated by his own experiments and then returned back to the U.S. and his family manor, where his father (a paranoid arch-conservative) had him killed and the body buried. Since Howard destroyed the records before defecting, the IMF must recover the body to get a sample of the chemicals. The IMF gain access to a air-raid shelter on the grounds and start "haunting" Justin with a secretly-implanted microphone and holographic projectors.
