Query: Jim Thompson: Unheralded Master

It is time people woke up and gave this man his due. Whenever I think of the current crop of so-called "mystery" or "thriller", my stomach turns to think that people read the kind of pablum that a writer like Sue Grafton spews out of her money-making writing machine. Thompson is a man who wrote real people in real situations and never once did he slip on their psychology. Lou Ford is a small-town Texas sheriff who deep-down possesses a desire to kill again and again and he doesn't hold it in because he doesn't want to. Here is a character who is the Id embodied, and when you read his thoughts you feel that he is all there but at the same time the undercurrent of his psychosis pulls at you a little. As the book progresses, Lou slips deeper into his bloodlust until it eventually ruins him. A great surprise ending and a convincingly-portrayed destruction of a regular Joe who just has to kill.
