Jill Halfpenny leads the cast in brand new Channel 5 thriller The Holiday, following a woman who goes on holiday with her family and four of her closest friends, only to learn one of them is having an affair with her cheating husband. To make matters worse, one of the group winds up dead at the bottom of a cliff.

The drama series is based on Sunday Times bestseller The Holiday, although there will inevitably be differences between the book and the TV series, as Jill Halfpenny has explained, stating she is feeling ‘very realistic’ about viewer reaction.

The series remains “pretty close” to the novel, Halfpenny told RadioTimes.com: “Towards the end there are a few little changes here and there but other than that, I would say it was it was pretty close.”

She continued: “It’s always difficult when somebody loves a book that’s been adapted because you can’t get the amount of detail and nuance in a drama that you get in a 600-page book, otherwise it’d be a 20-episode drama. So I think people do always feel like, ‘Oh, you didn’t put the part in that was my favourite.’ But there just has to be a choice when you’re adapting something and the story has to keep moving.”
