Steven Dunne was born in Bradford, West Yorkshire. He went to the University of Kent after A levels and studied as little as possible, yet somehow emerged with a second class honours degree. He began writing articles for quality newspapers on dull subjects before writing the book for the Latchmere Theatre's award-winning fringe production of Hansel and Gretel in 1989. He co-also co-wrote the revue, It's Mad Mad World, We're Plastered performed at the Rhoda McGaw Theatre in Woking the previous year and played the role of Teddy in the same theatre's production of Harold Pinter's The Homecoming the same year.
In the 1996 he moved up to his adopted home town of Derby. In 2007, he self-published Reaper, a thriller set in the city, featuring the hyper-intelligent but mentally troubled detective, DI Damen Brook.

He is currently writing the 6th book in the DI Brook series, entitled Death Do Us Part and the 5th in the series, A Killing Moon, won the coveted literary prize the East Midlands Book Award in 2016.
