Altered egos

An ordinary man trained to kill becomes dangerous ... a mind clouded by drugs makes him unstable. When he loses everything he loves, he becomes a lethal killing machine ... DI Mike Nash investigates a suspicious house fire, the bizarre murder of a young drug addict and the disappearance of a scientist's daughter. When animal rights activists target a laboratory, Nash and his colleagues are overwhelmed by the upsurge in violence. Their enquiries point to a man with a burning desire for revenge - but are more sinister forces at work? Nash must penetrate a cloak of secrecy to establish the truth.
