Bad Blood — James Goss

One of Annie's oldest friends has come looking for her - and what's more amazing is that she's found her. Denise is the ultimate party girl, and she's determined to bring Annie out of her shell. Mitchell is delighted, but George really thinks the last thing they need to do is to go out and meet new people.

Annie and Denise throw themselves into organising a Bingo night at the local sports hall - after all, it's for charity, and what's not to love about having a good time? But why is Denise back in town? Why have Bristol's vampires suddenly started hanging around wherever they go? And why does George get the feeling that Bingo night is going to go horribly, horribly wrong?

Featuring Mitchell, George and Annie, as played by Aidan Turner, Russell Tovey and Lenora Chichlow in the hit series created by Toby Whithouse for BBC Television
