"Anyone who goes to the haunted house never returns"

An electronics design engineer detects an apparition while testing a thermal camera. The thermal signature was clearly different from a living human being. But it disappears in a flash. This sets him off on a mission to prove the existence of ghosts.

He investigates a number of cases in the next five years. None of the cases provides enough evidence to prove the existence of ghosts. He is about to give up his research, when a potential case involving a haunted house gets him back to ghost hunting.

Last Adventure, like a roller coaster, starts slow, gains momentum, has its twists & turns, and finishes with a sense of calm contemplation.
