The Butcher's Theater by Jonathan Kellerman
Jonathan Kellerman is one of the worlds best authors. He uses his expertise as a clinical psychologist to write phenomenal books of suspense. He has won a variety of awards for his work including the Goldwyn, Edgar, and Anthony Awards and has been nominated for the Shamus Award.
In the book The Butcher's Theater, Daniel Sharavi and his crack team of investigators are called in to the ancient hills of Jerusalem, which is called the Butcher's Theater, where, upon a bloodstained stage, the faceless killer performs his violent specialty.
From the sacred wailing wall to the Black-clad allies, Chief Inspector Daniel Sharavi and his team plunge deep into a city simmering with religious and political passions, to hunt for a murderer whose taste for bloodshed could destroy the delicate balance on which Jerusalem's very survival depends.
The Butcher's Theater is a roller-coaster of suspense in a beautiful setting. It is so impossible to put down that I read it in one day, and it and kept me on the edge of my seat until the very last page.
I really like Kellerman's books because they keep the anticipation bubbling and the pages turning, and the Butcher's Theater is one of his best.
