My Ghost Story

In the beginning of Mary Shelley's Fankenstein, she uses four letter from Robert Walton writing to his sister while on his voyage to the Artic Pole. Walton travels to the Artic Pole to find magnetism. While on his trip, he comes across a stranger who begins to tell Walton a story about his life. The stranger tells his story through Walton & that begins chapter one. If I were to write a ghost story, I would begin with someone's personal, yet true, experience with a ghost. Then the rest of my story would be a similar & fake story with a little exaggeration thrown into the mix... Like a ghost that kills or something. Maybe I should write a ghost story.. ?
