Detective Ryan McMillan is a seasoned investigator, and the case pulling him into the backwoods outside Knoxville starts as a missing persons report. It does not stay that way. The trail leads to a decaying estate that holds more than its crumbling walls suggest: cryptic clues, long-buried secrets, and the restless presence of those who left things unresolved. Every room in the estate contributes a piece of the puzzle. Every object has a story attached. Not every spirit in this place has made peace with what happened here. Will you solve the mystery — or join it?
