On Laughton Moor

Detective Sergeant Catherine Bishop has an enigmatic new boss, Detective
Inspector Jonathan Knight. How he will adapt to life in Lincolnshire
after years in the Met is anyone's guess. 
When the body of a well
known local thug is discovered, an intriguing message found on his
battered corpse raises unwelcome questions. Is DS Bishop herself being
accused of the grisly murder, or does the message point to a more
sinister secret? As the body count grows higher, Bishop and Knight
find themselves in a race against time to discover the identity of a
merciless, faceless killer whose motivation is a mystery.
