A trio of powerhouse authors, Belinda Bauer, Eva Dolan and Erin Kelly, will share a stage.
Bauer rocked the literary world when she was longlisted for the 2018 Booker Prize for her novel, Snap.
Eva Dolan’s standalone, This is How it Ends, is one of the most critically acclaimed thrillers of the year.
Erin Kelly’s novels have been adapted for TV and dominated the bestseller lists, with her latest, Stone Mothers, an irresistible novel of psychological suspense.
Master of the suburban thriller and Netflix collaborator, Harlan Coben, is the perennial No 1 New York Times author of 30 novels.
The American will be in conversation with Rebus creator, Ian Rankin.
Val McDermid, who co-founded the Festival with literary agent Jane Gregory and arts charity Harrogate International Festivals in 2003, will also be in conversation with Scotland’s First Minister, and bookworm, Nicola Sturgeon.
The writer behind BBC1’s The Bodyguard, Jed Mercurio, also stars. With viewing figures exceeding 10 million, The Bodyguard, starring Richard Madden and Keeley Hawes, returned us to a time when a TV show could be a national event. One of the most successful TV writers at work today, Mercurio is behind many hit series, including Line of Duty.
Mari Hannah, said: “Announcing James Patterson in my year as festival chairman is a huge honour. Harrogate has a reputation for its powerhouse special guests.
“Every year, the programming committee work hard to attract the very best crime writers to the festival from around the world. The response to 2019’s line-up has been incredible. I’m looking forward to welcoming readers in July.”
Alongside the starry headline names, the Theakston Old Peculier is renowned for supporting emerging talent, with Val McDermid’s annual New Blood panel and a day-long creative writing workshop, Creative Thursday.
It is also a hotbed of debate. Famed for its no barriers approach, fans, fledgling writers and established superstar authors mingle in the hotel bar. Around 90 authors take part over four days of panels, late night events, and author dinners. The full programme of events will be announced in April.
