If Charles is the Alpha of the werewolf clan then Anna is the Omega thus all of this makes them the perfect power couple. The union of these two powerful beings was seen in Alpha and Omega for the first time when they embraced each other as mates. Anna thought that being a werewolf would be so much fun and it was fun at the beginning and later she started seeing the dark side too.
There are dangers of different kinds which are looming over the head of werewolves all the time. Charles is the enforcer and the son of the leader of the North American werewolves which makes him the one who has to take care of the issues of his clan as well. Here it becomes personal when Charles’ rival gets killed all of a sudden.
All the werewolves think that Charles is behind the crime and this means that he has to bear the punishment. The punishment for killing another werewolf is death in this world and Anna does not want to lose Charles in this way. She is confident that her mate has not committed the crime. To prove that Charles is not guilty, the couple has to find the real killer before it gets too late.
Patricia Briggs is the author of the series so the flavor is sky high as it was in Silence Fallen. Charles and Anna are on a dangerous mission so the narrator Holter Graham had to give a high-pitched voice to these werewolves in the current episode. The real killer is operating very cleverly from behind the veil and to unveil his true identity Charles and Anna had to trust their instincts.
