Chris Longmuir has won the £10,000 Dundee International Book Prize , said to be the most valuable literary award for an unpublished writer.
Her winning crime novel, Dead Wood, is now available from Polygon, which runs the prize with the University of Dundee and with the 'One City, Many Discoveries' campaign.
Longmuir left school at 15 with no qualifications, but gained an Open University Degree at the age of 40 and a postgraduate qualification in social work two years later. She has had stories published in My Weekly, People's Friend, and Dark Horizons.
The protagonist of Dead Wood, Kara, turns to prostitution to repay a debt, and finds herself embroiled in a world of gangland rivalries and retributions.
