North Forkers will have a chance to hear one of Long Island’s most knowledgable ghost hunters this afternoon when author Kerriann Flanagan Brosky comes to the Cutchogue-New Suffolk Library to discuss the ghosts of the North Fork.

Ms. Brosky, who has written five non-fiction books of Long Island history (some about ghosts, and some not), will also share sections of her recently released first novel, “The Medal.”

“The Medal” is the story of a Northport bakery owner in her late 20s, who is taking care of her ailing father when she becomes involved with the legend of Padre Pio, an Italian saint who was known for his healing abilities and for bearing the stigmata of Christ on his hands.

The lecture begins at 2 p.m.

“My main discussion will be the ghosts of Long Island, what it’s like being a ghost investigator and my research as a historian,” said Ms. Brosky, a Huntington resident who was writing about Huntington history when she met clairaudient medium Joe Giaquinto, who introduced her to the world of ghost hunting.

“People say to me, ‘you don’t look like a ghost investigator. You look like a soccer mom,’ ” she said. “What I do has a lot to do with local history.”

Ms. Brosky will discuss the Wickham murders of 1856, the haunting of the Jamesport Manor Inn and other ghost tales from nearby.

“The North Fork is a hot spot. So is the whole East End,” she said. “Every place has ghosts, but there tend to be more in places that have their history intact.”
