This story was one I really enjoyed, because, well, when an author can throw two people together with bad blood between them, similar creepy fascinations, and a power-saw, and manage to not end up with body parts strewn around, then you know for sure that they have some real imagination.
Though I don't recall the Pseudopod story's name, there was another one which was practically the opposite of this one. It starts off with a man with the power to change his appearance to that of anyone, the author tried to make you believe that he has got his lucky day, but because it was on Pseudopod, when the "twist" came and revealed to us that: Shocker! Things weren't going to be okay after all, I just sort of shrugged and said "... and?" This one had me expecting blood and viscera, but instead I found an interesting story, which was exactly the sort of twist I didn't see coming.
