Run by Faber and Stylist magazine. The only rule is that it has to be a female protagonist:

That's an interesting comp. Shows which way the wind is blowing in crime fic, apart from anything else...
Interestingly, when I went in to Faber to talk about the contemporary crime novel I ended up not writing, one of the things that was suggested to me was that I make the protagonist female.
Presumably a 'grizzly serial killer' is one that stalks Yellowstone Park and kills bears?
But seriously, that competition looks great. Thanks for posting.
