The Call of Cthulhu

The Call of Cthulhu is a short story by American writer H. P. Lovecraft. Written in the summer of 1926, it was first published in the pulp magazine Weird Tales in February 1928.
The story's narrator, Francis Wayland Thurston, recounts his discovery of various notes left behind by his great uncle, George Gammell Angell, a prominent professor of Semitic languages at Brown University in Providence, Rhode Island, who died during the winter of 1926, suspecting eldritch goings-on after being bumped into by a 'nautical-looking negro'.
