The Hundredth Man is one of the most original and interesting police procedurals I have read. Mr. Kerley has a powerful imagination and the writing ability to make the story live for a reader. The only thing that's missing is creating a chilling sense of dread of the sort that having truly creepy and threatening villains can bring. I missed that element. I was hoping that there was a Hannibal Lector character hiding away in the story somewhere. Close, but not quite.
The story comes across as though it is the second in a series, so perhaps we will be treated to a prequel someday to fill in the interesting background of how Carson Ryder became a police detective with a specialty in dealing with the psychology behind crimes.
Carson Ryder and his partner, Harry Nautilus, form a two-man unit, PSIT (humor apparently intended) that is frequently on the receiving end of that invocation from politically ambitious members of the force. They are called in to handle a case involving a headless corpse found in a park. The primary clue involves an unusual message placed in an unusual location. What does it mean? If you can figure it out, you're a genius. I don't recall such an original concept for a clue. More crimes follow and the partners find themselves having as much trouble with their superiors as with the uncaught criminal.
The story has marvelous misdirection that keeps the plot humming along.
Unlike many first novels with fine plots, the story has intriguing and original characters whose stories will fascinate you. I was disappointed that these characters were not developed even more. They move past their difficulties a little too easily for my taste.
The book is filled with complex and unusual psychology, and you will probably find yourself intrigued by seeing the world from the dark side in new ways. In the process, you will learn a lot about the complexities of how people cope with dysfunctional family experiences.
If you find the ugly details of how people harm others to be very upsetting, you may want to skip this book. It may affect your dreams.
I took away the lesson that we all need to be kinder and more helpful to one another. This book certainly makes that point very well.
