I would give this a 10 out of 10 if I could. Fantastic story. The men on the murder squad are a noble group of detectives facing the difficult task of rounding up a pack of psychopaths. I was not fond of the italicized chapters featuring one of them. I wish there was more on the characters of the secret society. The story was gripping, a noose that tightens as the story progresses. Highly recommended!
I wouldn't characterize the story as ultra violent. But the tension is there and there are certainly moments of bloody horror.
