Writing this story was like scratching an itch--I'd left poor Sylvia in pieces at the end of Kiss of Life, and then she ended up on the cutting room floor (pun intended) in Passing Strange after I'd excised a long chapter that more fully resolved her situation than her brief cameo in the final book hinted at. I wasn't pleased with making the deletion at the time, but in retrospect the cut made more sense for the novel, and "Doll Parts" was the easiest of the four stories to write. I knew the tone I wanted, I knew the beginning the middle and the end, so all I needed to do was try to get the order of the words right.
My first publications for pay were horror short stories, and "Doll Parts" is similar in tone. And yes, for those of you who are aware of my worshipful love of Mystery Science Theater, the initial inspiration for the story did come from a movie they spoofed called The Brain that Wouldn't Die. That, and the idea that the existence of zombies would provide all sorts of challenges and opportunities to our medical community, some of which would not be approached with good intentions.
