H. P. Lovecraft 
Dagon [EPUB ebook] 

Dagon is a short story by H. P. Lovecraft, written in July 1917, one of the first stories he wrote as an adult. It was first published in the November 1919 edition of The Vagrant (issue #11). The story is the testament of a tortured, morphine-addicted man who plans to commit suicide over an incident that occurred early on in World War I when he was a merchant marine officer. In the unnamed narrator’s account, his cargo ship is captured by a German sea-raider in "one of the most open and least frequented parts of the broad Pacific". He escapes on a lifeboat and drifts aimlessly across the sea "somewhat south of the equator" until he eventually finds himself inexplicably stranded on a slimy expanse of hellish black mire.
