A middle-class family is murdered in a quiet affluent suburb, with the killer leaving a bizarre calling-card. Within days, more murders are discovered across the country with the same bizarre calling-card left behind.
With no apparent link between the victims, Detective Sergeant Steve Denton and his colleagues must uncover the motive and stop the killer before they strike again.
Stood in Denton's way is a criminal known only as The Broker, who is being offered millions to keep the body count rising, and to keep the police guessing.
