Dead Ringer

Dead Ringer is a science fiction short story by American author Lester del Ray, first published in 1956.

There was nothing, especially on Earth, which could set him free—the truth least of all!

A newspaperman is hounded from his jobs because he keeps trying to report aliens who can't be killed--they heal, even from death – just like zombies.

And now the authorities want to institutionalize him…

Dead Ringer was first published in Galaxy Science Fiction November 1956.
