Title: Vampire Weekend
Air Date: October 26, 2009 at 12:00 AM PDT
As Halloween approaches, Castle and Beckett are called to a graveyard where the body of a young man sporting vampire fangs has been discovered with a wooden stake driven through his heart. Their investigation takes them deep into the heart of an underground vampire fetish community, where they learn that the motive for the victim's murder may be hiding within the pages of the graphic novel he was writing before his death. In the meantime, Castle tries on costumes for his Halloween party. Count Dracula, perhaps?
