Organised by Aberdeen Performing Arts (APA), Granite Noir will also welcome authors from Scandinavia to talk to audiences about their novels.

Other events will include film screenings, and workshops for children.

Crime author and event ambassador Stuart MacBride told the launch event on Sunday night: "It will be a phenomenal festival with some spectacular events.

"I would like to see Granite Noir leading the way, and see us becoming a city of literature."

APA chief executive Jane Spiers said: "Aberdeen will be in the grip of Granite Noir in February as we bring our crime fiction festival to venues across the city.

"Our inaugural event earlier this year was a huge success, with multiple sell-out events.

"This year we're bringing more authors and more variety, with something for people of all passions and ages."
