Nikki Heat is the fictitious detective in writer Richard Castle's (non-existent) novels based on fictitious NY detective Kate Beckett played by real life Serbian - Canadian actress Stana Katic on the TV show "Castle." Formerly she played a Vampire in the movie "The Librarian." Usually in jeans she ocassionally goes undercover. Usually she packs two '38s but here she is modeling her new "panty-holster" As usual manipped everything
I got the idea from some of her costumes. As a Vampire she spent half the movie running in around in a tight skirt and in "Castle" she poses as a Call girl.
