A Colder War

Blurb

"A Colder War" is an English-language, alternate history novelette by Charles Stross written c. 1997.
The story fuses the Cold War and the Cthulhu Mythos by exploring the consequences of a follow-up to the expedition in H. P. Lovecraft's At the Mountains of Madness. Although the story has similarity to the later Stross novel The Atrocity Archives, they are set in different universes. Teresa Nielsen Hayden describes the story on Making Light as "It's the Oliver North/Guns for Hostages scandal, seen from the viewpoint of a CIA bureaucrat, in a universe in which the entire Cthulhu Mythos is real."
It was one of Locus Online's 2000 'Recommended Reading' novelettes.
