The supernatural enhancements

In 1995, A. and his companion, Niamh, a mute teen girl from Ireland, arrive in Virginia to take possession of Axton House, a mansion left to A. by a distant cousin. The pair soon come to realize the house is haunted by a ghost, possibly the relative that committed suicide there like his father had before him. Told in journal entries, ciphers, security footage, and letters, A. and Niamh recount what happened to them in Axton House.
