Organisers have hailed this year’s Granite Noir festival as the most successful yet since it launched four years ago.
Thousands of people flocked to the city over the last four days to attend the event.
Talks from acclaimed crime writers Ian Rankin, of Inspector Rebus fame, and US author Sara Paretsky headlined the popular festival.
In total, there were 40 events and exhibitions for locals and visitors to enjoy, with other highlights including talks by Ben Aaronovitch, Belfast DJ David Holmes and also Dr Kathryn Harkup who explored the science of poison.
Audiences enjoyed walking tours, escape room activities, a courtroom drama and writing workshops.
The festival attracted 12,000 attendances and had a 33% increase in ticket sales from last year with 9,000 sold.
Visitors came from as far afield as Canberra, Kentucky and Arizona, while others travelled from Oxford to Orkney in the UK.
Granite Noir is produced by Aberdeen Performing Arts on behalf of Aberdeen City Libraries, Aberdeen City and Aberdeenshire Archives and the Belmont Filmhouse.
Aberdeen Performing Arts chief executive Jane Spiers said: “Granite Noir has captured the imagination of the city and put Aberdeen on a world stage.
“It’s been a huge hit with audiences and artists alike.
“What an amazing weekend it’s been, many of the events completely sold out and there has been a real buzz around the city.
“This is the fourth Granite Noir, and audiences have tripled since we started out in 2017.
“We’re genuinely thrilled that so many people have come along from far and wide.
“Support locally for Granite Noir has been terrific. Our local audiences are our biggest ambassadors.
“It’s a really ambitious festival to stage across the city and we can’t thank our partners and collaborators enough.”
A free exhibition drawn from the Aberdeen City and Aberdeenshire Archives, entitled Outcasts: Women, Crime and Society, attracted national attention and a large number of visitors through the Lemon Tree and the Music Hall.
