From multi-million-selling Joy Ellis, one of Britain's best-loved crime writers, with over twenty number-one bestsellers. Meet Detective Nikki Galena. She will stop at nothing to avenge her daughter. Under the brooding skies of the Lincolnshire Fens, she pursues the most vicious criminals. The Detective DI Nikki Galena: A police detective with nothing left to lose. She's seen a girl die in her arms, and her daughter will never leave the hospital again. She's got tough on the criminals she believes did this to her. Too tough. And now she's been given one final warning: make it work with her new sergeant, DS Joseph Easter, or she's out. Her Partner DS Joseph Easter is the squeaky-clean new member of the team. But his nickname "Holy Joe" belies his former life as a soldier. He has an estranged daughter who blames him for everything that went wrong with their family. Their Enemy A ruthless man who holds DI Galena responsible for his terrible disfigurement. The town is being terrorised by gangs of violent thugs, all wearing identical hideous masks. Then a talented young female student goes missing on the marsh and Nikki and Joseph find themselves joining forces with a master criminal in their efforts to save her. They need to look behind the masks, but when they do, they find something more sinister and deadly than they ever expected . . . The Setting The Lincolnshire Fens: great open skies brood over marshes, farmland, and nature reserves. It is not easy terrain for the Fenland Constabulary to police: with remote Fen villages, dangerous and often misty lanes, and poor telephone coverage. There are still villages where the oldest residents have never set foot outside their own farmland. A visit to the nearest town is a major event. But it has a strange airy beauty to it, and above it all are the biggest skies you've ever seen. This totally gripping mystery is perfect for fans of L.J. Ross, Angela Marsons, J.D. Kirk, Elly Griffiths and Ann Cleeves.
