The Nocturnal Minstrel; Or, the Spirit of the Wood — Eleanor Sleath

Sebastian Park, hack ghost hunter, is called to Peachtree, Vermont, to help rid them of a black, aggressive mist that the townspeople believe is a negative entity. When it comes to paranormal investigations, Sebastian is used to being the ringmaster in a circus full of clowns. But when he has the first nightmare and suffers the entity himself, and when he begins to have urges to gnaw on the girl at the local diner, he regrets his career choice and his cross-country trek to the nightmarish, little New England town.
