Mari Hannah is a multi-award-winning author, whose authentic voice is no happy accident. A former probation officer, she lives in rural Northumberland with her partner, an ex-murder detective. Mari turned to script-writing 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. Mari's body of work won her the CWA Dagger in the Library 2017, an incredible honour to receive so early in her career. In 2019, she was voted DIVA Wordsmith of the Year. In 2020, she won Capital Crime International Crime Writing Festival's Crime Book of the Year for Without a Trace. Her Kate Daniels series is in development with Stephen Fry's production company, Sprout Pictures.
