Nemesis is the first book in the Badge and the Pen series. The book features Detective Inspector Vinnie Palmer, a man who is about to undertake the most challenging case in his career. Psychopath Daniel Moxley has just escaped while on transit to the Broadmoor high-security prison. The bodies Moxley is leaving on his wake indicate that he is on a revenge mission, and no one he thinks has wronged him will escape alive. The murderous streak starts with the torturous killing of a police officer. A cat and mouse game ensues, and the only thing the unhinged sociopath leaves in his wake is mutilated bodies. Thanks to his paranoia, Moxley will result in killing randomly, so there is no way of predicting his next victim.
