A little spicy? Serial killer Anthony demands copious amounts of spice, methinks. I love the beginning! Beautifully written.
(Have I ever asked if you'd write a Vampanthony?)
I can see Kate calling bullshit on Anthony's "serial killer gene" theory.
Oh the snippet is a little spicy, but the fic itself would be hard E haha. Sex and murder aplenty. A great fic kink combo. My vague idea is that Anthony recognizes a fellow deviant in Kate, but she's resisted her urges so far. He kidnaps her (or she goes semi-willingly in exchange for financial support for her family) and tries to encourage her to submit to her true nature. Their relationship gets intimate and intense, but he won't give her everything she wants until she finally kills.
I've gotten a few requests for a vampire fic, but I'm not too familiar with vampire lore. I know there are a few great ones in the fandom. A vamp Kate would be super hot too. Anthony would be like yes bite me, I'd happily die this way.
