There is an old saying. War changes a man. There is an even older saying. Wait for the second knock before you open the door.

Please note: This horror story is not appropriate for all audiences and includes elements of supernatural horror and violence. Care should be taken to ensure only age-appropriate readers lay their eyes on this. Actually... Even if you're old enough, we're not promising you this tale of terror won't give you nightmares. Seriously, though. No kids!
