Halloween train

It was about a year ago. I was on the express train from Edinburgh to my parents in London.
Train guard showed me the way to my compartment

It was really nice and spacious, with me in there was a woman with her son and a girl, who looked 18-20 years old. The service was a first-class one

At dinner we got into conversation. Katie (that was her name) turned out to be very kind and sociable. We chatted with her about everything in the world until nightfall.

In the morning I woke up and immediately decided to check if Katie got up.
But she was not there. I thought, she got up before me and was walking along the train.

I went to breakfast and started doing the crossword puzzle. I was so carried away that I completely forgot about Katie.
Having solved it, I discovered that Katie and her things were not there. Maybe she got off at the station? - I thought
But I immediately threw this thought away. She would definitely tell me about it.

I decided to ask a woman, who was lying on the upper berth.
Her answer shocked me. She replied that there was no Katie.

I decided to ask the conductor if she knew about Katie.
But she replied that there were only three people in our compartment.

In the evening I was already in my hometown. I completely forgot about Katie.
It was only recently that I learned one thing. Katie actually died on this train. Once at the station she was attacked and killed, taking all her things.
The killer was never found. And Katie's spirit has now settled in this train. I will never forget it.
