H. P. Lovecraft 
Dunwich Horror 

In the degenerate, unliked backwater of Dunwich, Wilbur Whately, a most unusual child, is born. Of unnatural parentage, he grows at an uncanny pace to an unsettling height, but the boy’s arrival simply precedes that of a true horror: one of the Old Ones, that forces the people of the town to hole up by night.
