The Hunting Wind by Steve Hamilton

If you like those old 1940's detective stories by Raymond Chandler or Dashiell Hammett, you will like Steve Hamilton. Alex McKnight, the central character of this series, is a contemporary version of the tough, principled, yet flawed detective of  yore. Like them, he has a hard crust but a soft interior, and it is often his sentimental side that gets him into trouble, which he then must get out of with guts, guile and some luck. He's not a superhero like Jack Reacher, but gets the hell beat out of him at least once per novel. He just wants to be left alone to tend his cabins in the Michigan hinterlands, but as they say, trouble has a way of finding a guy.
