It is a golden rule: if you visit or move to a new area and the locals issue a chilling warning, abide by it.

In books and films, the golden rule is to ignore it.

Take ´American Werewolf in London´, where the two Americans stray off the path of the Yorkshire Moors and one of them is killed by a werewolf.

In 'The Moon-Bog', an Irish-American reclaims his ancestral estate in Kilderry, Ireland.

The superstitious local peasants plead with him not to drain the nearby bog. Which, of course, he does - with terrifying supernatural results.

This short story is perfect for those already familiar with the writings of H. P. Lovecraft, or those simply looking for a quick scare.

Howard Phillips (H.P.) Lovecraft (1890-1937) was an American author famed for his horror and fantasy fiction.

Born in Rhode Island, he became a pioneer of ‘cosmic horror’, conjuring up the lore of supernatural creatures who exist beyond our understanding. His best-known stories include "The Call of Cthulhu", "At the Mountains of Madness" and "The Colour Out of Space".

While he was a mainstay of pulp magazines, Lovecraft never achieved wider literary recognition in his lifetime. But his posthumous influence has been profound. It can be found in everything from the fiction of Stephen King and Neil Gaiman to the HBO series "Lovecraft Country".
