1st version of short story.

He was walking through the lonely streets of a London night. Prostitutes came up to him asking if he would like to be accompanied to the bar. He would look up from under his hair and they would walk away quickly. His dark figure scared yet attracted many people. Eyes would stare at him and look away quickly if his head even twitched. Christoph walked into the nearest tavern to what the bartender would say “wet his whistle.” He didn’t think of it like that. He saw the tavern as a place to observe the towns people in a rather oblivious state. This was also a time to feed. Feed on the energy of the bodies, on the knowledge of the heads, and the blood of life. Christoph watched a young girl around the age of 16 tending to a drunken man. He watched how she delt with the slurred lewd comments, the touching and grabbing, and the alcohol. She left the table after being harassed, and went behind the counter and poured a shot. “Just another night” she said before she poured the liquid down her throat. She set her glass down hard and made a face as if she just ate a lemon. “Do you need anything sir?” “No I’m fine, thank you.” She walked away with a loud sigh. Christoph watched her with curiosity. She walked with a certain sway that invited comments and devilish looks. Christoph wanted to know her name. He must know her name. She swayed by and he tapped her. “You need something now?” She said. “Yes, what is your name?” “Claudia, so do you need a drink?” “No, thank you. I think I’m done for the night.” Claudia stared at him in question as Christoph got up and walked away. He stepped back into the cold crisp night of London. Again prostitutes greeted him in hopes of making some money. He felt a little weery and cold so he waved to one of the girls for her to follow. They walked down a dark alley way with her pimp to follow behind. As he propped her against the wall she lifted her skirt and stared into his eyes. Christoph pulled her head back and went to kiss her neck. She closed her eyes in anticipation. Blood trickled down her neck. Her eyes wide now and her mouth open with nothing but silent screams. He was full now. Dropping her body to the floor. He stared at the young lady. Maybe she was only 18. Maybe it was best that this was her last job. He stared for a few more seconds and threw coins to the body. He walked back down the alley and the pimp approached him. “Wow you must have tired her out, she’s laying on the floor!” “Yeah, something like that I guess.” Christoph said as he walked away. 30 seconds later he heard the pimp curse and yell. Christoph fell deep into the fog of the night and wasn’t seen by the pimp ever again.
