It's told well, Coch. It's a bit fast but in a short story that's to be expected. I caught one misspelled word, again nothing major.

On the whole I liked the story. If I may suggest, if you decide to redo this, a description of Thorians or the monster may help the reader a bit after he gets out of the hospital, since he kept detailed notes it would be likely he'd pick them out and write them down when he gets back. Without a knowing the monster is there it seems like he's afraid of being alone or out in the open or something like that. It may not be what you wish to get at, but that's entirely what it speaks to me.

Still nice story.

Thank you. I'm not too sure right now if I'm going to do anything with it. However, If I do decide to expand upon it I'll be sure to take your advice into consideration.
