Monster

The carriage was nearly empty. There was one young man who briefly looked up from his phone as I came in. I sat in the corner seat and looked out of the window.

The train went through a tunnel and, for a few seconds, the view outside disappeared to be replaced by the reflection of the inside of the carriage. My fellow traveller looked... strange. I had a confused impression of teeth and talons and then the train emerged into darkness and the reflection had gone. I looked at the man - engrossed with his phone.

I wasn't sure what had happened - a trick of the light or of my mind? But the one thing that I was sure of was that the creature that I had glimpsed had been staring intently at me.
