In the sixties I remember reading a story where a group of men are searching for an unknown, unseen monster who was killing people and destroying property. At one point, the men barricade themselves in a cabin/house while two men are looking out windows keeping watch. In the morning the watchers are still at the windows but it's discovered their faces have been ripped off.
For 45 years I've thought the story was The Dunwich Horror by H. P. Lovecraft. Today I discovered that it's not. I'm trying to decide if this scene is from a different story, Lovecraft or other author, or if it's an invented memory. Any ideas?
