Peripheral Vision — Susan Hart

Shadows: Jeff, his mind and body pretty much wasted after years of drug-riddled parties, starts to see shadows and he leaves his house to try and clear his head. But, the shadows are still there. When he returns, his gorgeous landlady from next door is in his house and tells him that she will explain what's been happening; if she can. Stalked By The Slender Man: A story about a young woman who's been stalked by a faceless stranger since she was a child and when she turns eighteen he makes his move; and after having sex with him a few times, he tells her who he really is and also, why he's been stalking her all of her life.
