“Dead Ringer,” Lester del Rey, 1956 — (Alternate title: “And the truth…”) Dane Phillips is a journalist trying to alert people to the presence of alien doppelgangers that can resurrect after death, but he’s treated as a crackpot. After being psychoanalyzed, his therapist claims this is a neurosis stemming from the death of his father in his childhood. Phillips continues to try to expose the conspiracy but all efforts fail. In despair, he looks in a mirror, prepared to slit his throat. When he finally works up the nerve, he watches in amazement as his skin heals itself.
