Never Lie (1970)

A newlywed couple on the search for the house of their dreams when they come upon a remote manor that once belonged to a renowned psychiatrist, a woman who vanished four years earlier. Trapped at the estate due to an intense blizzard, the wife happens upon a secret room containing audio tapes of the psychiatrist’s interviews with her patients, discovering one session is with a sociopath who sounds scarily familiar to her.
