Mari Hannah is an award-winning author whose authentic voice is no happy accident. A former probation officer, she has contributed to CID training for Northumbria Police and lives in rural Northumberland with her partner, an ex-murder detective. Mari turned to scriptwriting when her career was cut short following an assault on duty. Her debut, The Murder Wall (adapted from a script she developed with the BBC) won her the Polari First Book Prize. Its follow-up, Settled Blood, picked up a Northern Writers' Award. She went on to be shortlisted for the Dagger in the Library and is currently Reader in Residence for Harrogate International Crime Writing Festival.
