Graham Brack hails from Sunderland and met his wife, Gillian, in Aberdeen, where they were both studying pharmacy. After their degrees Gillian returned to Cornwall and Graham followed. This is now called stalking but in 1978 it was termed "romantic." They have two children, Andrew and Hannah, and three grandchildren, Miranda, Sophie, and Olivia. Gillian and Graham now live in Northamptonshire.
Graham's foray into crime writing began in 2010 when he entered the Crime Writers' Association's Debut Dagger competition and was highly commended for Lying and Dying (previously titled The Outrageous Behavior of Left-Handed Dwarves), in which the world was introduced to Lt. Josef Slonský of the Czech police. Slaughter and Forgetting followed. Both have been republished by Sapere Books along with another four in the series, Death On Duty, Field of Death, A Second Death, and Laid in Earth.
In 2014 and 2016 Graham was shortlisted for the Debut Dagger again. The earlier novel, Death in Delft (previously titled The Allegory of Art and Science), is set in seventeenth-century Delft and features the philosophy lecturer and reluctant detective Master Mercurius. Sapere Books published it in 2020.
