Lisa Jewell (live from the Crossed Wires Festival)

Sara heads to Sheffield, for the Crossed Wires Festival, to speak with international bestselling author Lisa Jewell, in front of a live audience.

Lisa chats about her new thriller, 'It Could Have Been Her', as well as her writing inspirations, the Harrogate Crime Writing Festival and how she turned from writing commercial 'women's fiction' to dark psychological thrillers.

She also reads us a short extract of the novel, recommends us some books and takes audience questions too.

Here's a little more info on Lisa's new novel:

Jane Trevally, newly divorced and feeling a little lost, agrees to accompany a man she doesn't know to his house in the darkest corner of Hampstead Heath. She's offered a drink, goes in, and then - a scream and the sound of something falling upstairs - Jane senses she's in a bad place. She runs.

Twenty five years later, Jane finds herself outside the same house, this time to return a small white dog who's been found near her home in the country; a dog whose owner has just been reported missing.

A fleeting glimpse of a haunted looking woman through the window sends Jane on a mission to uncover the house's secrets - secrets more terrifying than she could have ever imagined, especially when she realises it could have been her. .
