This book has two stories. They are about ghost. The first story is that a strange accident happens when the signalman sees the ghost. I think that this ghost tells him about the accident will happen, so this ghost isn't a bad one. And the second story is that a man sees a ghost during a trail of murder case. The ghost which the mam sees is a victim of the case.
