Di dressmaker’s TV killer thriller

She made dresses worn by Princess Diana before becoming a best- selling novelist. Now Bella Pollen reveals she’s getting in touch with her darker side.

‘I’m writing an original television series at the moment about a serial killer — I like bones and death,’ she tells me.

‘It’s different to anything I’ve done before. I’ve had books optioned before but none has made it to the screen, so hopefully this one will make it.

‘It’s part of a bigger scheme I’m working on, which is about missing migrants in the desert on the Mexican border. It’s a subject that’s quite close to my heart.’
