"As the younger sister of a werewolf and a vampire, Amy has a fascinating, but very disturbing lineage”, says Wallace. “She’s the perfect character with which to tell a coming-of-age story. Only this one has madness, murder, and monsters.”

Dark Shadows: The Lucifer Gambit stars Stephanie Ellyne as Amy and Big Finish newcomer Simon Lee Philips, playing Dominic. They're joined by screen legend Sheila Steafel as Dominic's wife, Isobel. “I worked with Sheila a few years ago when I produced her own reading of her autobiography,” says co-producer David Darlington. “And I've been looking for an excuse to work with her again ever since! She has form in playing spooks, too, as UK listeners who remember The Ghosts of Motley Hall could confirm. She really gave it her all, just as we'd hoped, and really enjoyed being a demonic diva for us.”

The full cast list, cover, trailer and behind-the-scenes photographs are now available here.

“This is a horror story about the consequences of gambling with your life,” says Wallace. “But it’s also about the only thing scarier than adolescence. And that’s adulthood.”

Dark Shadows (1966-1971) was a US TV series which told the story of the cursed Collins family. Set in the town of Collinsport, it featured witches, vampires, werewolves and warlocks plotting and scheming against each other. It was remade as a film starring Johnny Depp, now available on DVD.
