Eleven months after discovering a brutal double murder in a sleepy Northumbrian town, Detective Chief Inspector Kate Daniels is still haunted by her failure to solve the case. Then the brutal killing of a man on Newcastle's Quayside gives Daniels another chance to get it right, and her first case as Senior Investigating Officer. When Daniels recognises the corpse, but fails to disclose the fact, her personal life swerves dangerously into her professional life. But much worse, she is now being watched.
Mari Hannah was born in London and moved north as a child. Sponsored by the Home Office, she graduated from Teesside University before becoming a Probation Officer, a career cut short when she was injured while on duty. Thereafter, she spent several years working as a film/television scriptwriter. During that time she created and developed a number of projects, most notably a feature length film and the pilot episode of a crime series for television based on the characters in her book, the latter as part of a BBC drama development scheme. She lives in Northumberland with her partner, an ex-murder detective. In 2010, she won the Northern Writers' Award. The Murder Wall is her debut novel.
Mari Hannah was awarded the CWA 2017 Dagger in the Library, a prize for a body of work by a crime writer that users of libraries particularly admire.
