The Signal-Man (Charles Dickens)

The Signal-man is an incredible story based on the Gothic genre. The story begins with a person who meets a signal man who works by monitoring trains that pass daily near a tunnel. However, this worker tells him how a ghost has appeared twice and after the apparitions some tragedy occurs. And, the last time he sees the ghost, he does not know how to report that something is going to happen because he has no tangible evidence, and one day after that, the signal man died in a train accident. This is just a brushstroke of what the story is about.
