Gwinny Tuffel is on location in the misty Yorkshire Dales filming a small part in Draculania, a genderswapped remake of Bram Stoker's classic tale, when life begins to imitate art a little too closely. One of the cast members is found dead inside a locked trailer, with a stake through their heart. With a prima donna in the starring role, filming is already facing delays, while Gwinny is being run ragged by Lily, the Jack Russell terrier she's looking after for a friend in hospital.

Against the backdrop of Hendale Hall with its own vampire legend, a flesh-and-blood killer has struck. Will Gwinny be able to find the murderer before the production or any further victims are cut?
