Gertrude Franklin Horn Atherton (1857-1946) was a prominent and prolific American author of novels, short stories, essays, and articles for magazines and newspapers. Her horror stories are particularly popular.
'The Striding Place' (1895) tells the story of a man who is searching for his best friend, who's gone missing. The search takes him to a dangerous waterfall in the forest called The Strid, from which many have fallen and drowned. There he discovers something most terrifying and surreal.
