What a creepily good short story. I could guess from the beginning that the man was a ghost. it was something like the aura of the writing. I would suggest putting the author's not in a drop or pop note to set it off from the story. I would also increase the sized of the font to make it easier to read. THe breaks between paragraphs are good leaving the story in easily digestable chunks as would be necessitated by a dialog only story. I would be interested in reading a version embellished with a little more physical description in addition to the dialog, just to see if it added to it. It would mean I would better be able to see the man in his soldier uniform instead of just some obscure costume. that part wasn't really clear until the end.
