The series, previously only available as e-books through Joffe Books, is now out in physical form thanks to a deal with Bittern Books, a wholesaler specialising in East Anglia.
Judi Daykin said: “I was aware of Bittern Books for a while, but as Joffe Books is my publisher, I couldn’t reach out directly myself.
“It’s absolutely fantastic because now Bittern Books can help get my books into bookshops, not just online.
“There’s something about seeing a book you’ve created on a shelf in a shop.
“It feels like validation.”
All of Ms Daykin’s novels are set in North Norfolk and follow police officer DS Sara Hirst.
They are all inspired by the author’s life in the county.
Prior to lockdown, she’d spent most of her professional life as a working actor, touring the UK with her husband in various theatre companies.
Although born in Yorkshire, she moved to Norfolk forty years ago.
She was then a technician at the Pavilion Theatre at the end of Cromer Pier, which she said was a big influence on her life and work.
She said: “The Pavilion Theatre has a unique status in that, not only is it still open, but it still runs an old-fashioned seaside variety show in the summer.”
She retired from acting in the Covid pandemic and was accepted onto the University of East Anglia’s creative writing master’s course, where she wrote her first DS Sara Hirst novel.
Steve Haines, owner of Bittern Books, said: “As soon as I started reading Under Violent Skies I realised it was a real page turner.
“Judi’s books are all set locally, using locations around North Norfolk that locals and visitors will be very familiar with.
“We now have Judi’s books in stores all around Norfolk, including Waterstones and City Bookshop in Norwich, as well as many others around the county.”
