Lyra and BonBon go on holiday to the new resort of Mare-On-Sea, and learn of Hinnysmouth, a disreputable seaside village further up the coast. Despite misgivings, they decide to visit Hinnysmouth, and soon regret their curiosity.

( Inspired by Lovecraft's 'The Shadow Over Innsmouth', of course, and riffing on a certain meme. Some names suggested by Happerry - thanks! Despite the opening quote, not necessarily in the same universe as 'The Stars Will Aid Their Escape' )
