Hodgson's major novels include The Boats of the "Glen Carrig" (1907), The House on the Borderland (1908), The Ghost Pirates (1909), and his masterpiece The Night Land (1912), a haunting vision of a far-future Earth dominated by monstrous forces. He also created the popular occult detective Carnacki, featured in Carnacki, the Ghost-Finder (1913), and wrote numerous short stories about the sea, including the Sargasso Sea tales.
Although underappreciated in his lifetime, Hodgson's blend of cosmic horror and nautical adventure profoundly influenced later writers such as H.P. Lovecraft and Clark Ashton Smith. His life was cut short when he was killed at the Battle of Ypres in April 1918, leaving behind a legacy that continues to inspire modern fantasy and horror literature.
