Letting a man into her apartment because "she had a bad memory" sounds very unusual. If the man was up to no good he would probably be able to answer several questions that she might throw at him (all the while peering through the cracked door with the safetly latch connected). That way the reader might identify better with the girl and sympathise with her plight. Of course I don't know if that's what you'd really want! I liked your description of how she fell like "no more than a pile of clothes." You also succeeded in making me want to know what's going to happen. Like Dialyn, I hope what happens isn't just a bunch of gore and violence.
