Boyd tries to get to the truth by studying a list of the shrink's patients. While interviewing three of these worthies (Jack Hawkins, Diane Cilento and Richard Attenborough), Boyd discover that each has a deep dark secret that the psychiatrist was privy to. The best-kept secret concerns the schizophrenia of the dead man's teenaged daughter (Pamela Franklin)--a fact that provides the key to mystery. The Third Secret originally featured Patricia Neal as one of the suspects, but her scenes were cut from the final release print. ~ Hal Erickson, Rovi
