Unfortunately, this level of ugliness is intrinsically boring, once you get past the shock value. Kellerman's characters carry no weight. They are dopeheads, anorexics, muscle men, window peepers, pedophiles, drugged out nyphomaniacs. His LA is filled with perverts.
So, who cares? Kellerman's usual hero, Alex Delaware, and his relationship with tough gay LA police detective carry his stories to a more engaging level as the reader experiences their developing relationship and efforts to solve a mystery.
In this novel, the two brothers who are the central characters simply do not carry enough weight to offset the general ugliness and draggy plot. I almost didn't finish this book. The only mystery was the details of how the murders were perpetrated and which of the uglies actually murdered the victims and which egged them on.
Long boring paragraphs of mental speculation of all the possible combination of options. Yawn.
Kellerman seems to be running out of steam.
