Who Goes There?

A remote scientific research expedition at the North Pole is invaded by a monstrous alien, reawakened after lying frozen for centuries after a crash-landing. The alien is intelligent, cunning and a shape-changer who can assume the form and personality of anything it destroys and soon it is among the men of the expedition, killing and replacing them, using its shape-changing ability to lull the scientists one by one into inattention and destruction. The transformed alien can seemingly pass every effort at detection and the expedition seems doomed until at last the secret vulnerability of the alien is discovered and it is destroyed.Who Goes There? according to the science fiction historian Sam Moskowitz (1920-1997) had an autobiographical impetus: Campbell's mother and aunt were identical twins and enjoyed the "game" of substituting for one another in his care as an infant and young child, confusing him again and again with false identity. It was this uncertainty, this susceptibility to masquerade and his terror at the game which, Moskowitz said, Campbell funneled into this last and greatest of his magazine pieces. (A short novel, The Moon Is Hell, was published only in book form in the early l950's.) Carefully and rigorously extrapolated in its portrait of the menaced expedition, the novelette is regarded as perhaps the greatest horror story to emerge form the field of science fiction.
