'God, he's good.' STEPHEN KINGIF YOU SEE THEM - RUN...A clergyman is murdered in his bed in the dead of night, triggering a chilling chain of events, each more bizarre and unnerving than the last – brutal killings, corpses vanishing, decomposed bodies digging their way out of graves.These shocking events seem unconnected but, at each scene, people report witnessing swarms of flies – hundreds, thousands, even millions of them.As DI Patel and DS Pardoe hunt for the mastermind behind these atrocious crimes, they are forced to ask: is this person human – or is all of this linked to the mysterious figure caught on CCTV, running at speed without moving its legs?And can they stop the swarm before they themselves are consumed?For fans of Joe Hill, Peter James and Stephen King, Graham Masterton is a master of the horror genre whose books have sold millions of copies across the globe.Praise for Graham Masterton:'One of the most original and frightening storytellers of our time' Peter James'Suspenseful and tension-filled... all the finesse of a master storyteller' Guardian'One of Britain's finest horror writers' Daily Mail
