One night, two crimes. A grisly murder. A vicious sex attack. DS Ewan Striker is the best detective on the force. Unconventional and uncompromising, he is respected and feared in equal amounts. Tag Westland is a rookie. A rich boy, who has realised that being a cop is not as glamorous as he first thought. In fact, he has his resignation in his pocket. These two unlikely crime fighters are thrown together, as it becomes apparent that each of their investigations are inextricably linked to something even more evil. A major terrorist attack.
