"When the body of a man is found crucified at the top of a hill in the British midlands, AIDE Lock-the world's first AI Detective-and Detective Kat Frank are thrust into the spotlight as they are given their first live case. When a second body is found the police issue an extraordinary warning to local males aged between 30 and 40 years old: Avoid drinking in pubs; If you must go to a pub, do not leave alone; And definitely do not leave a pub with a stranger. With the national media and local men in an uproar, Kat and Lock have to combine their instincts and algorithms to catch the killer before they can strike again"-- Provided by publisher.
