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. 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. The first book in the Stone and Oliver series, The Lost, will be published as a paperback original in spring 2018.
