The Shadow Over Innsmouth

The Shadow Over Innsmouth is a novella by H. P. Lovecraft. Written in November–December 1931, the story was first published in April 1936; this was the only fiction of Lovecraft's published during his lifetime that did not appear in a periodical.

The story describes a young man's discovery of a strange hybrid race, half-human and half an unknown creature that resembles a cross between a fish and a frog, that dwell in Innsmouth – a coastal town that had seen better days – and the waters offshore. The townspeople worship Dagon, a Philistine deity incorporated into the Cthulhu Mythos.
