The Stranger You Seek by Amanda Kyle Williams

The Stranger You Seek introduces a new private detective:
  "My name is Keye Street. First name from my Asian grandfather; my adoptive parents awarded me the second. By trade I am a detective, private, that is a process server and bill recovery agent. In life, I am a dry alcoholic, a passionate believer in Krystal cheeseburgers and Krispy Kreme doughnuts, and a former behavioral analyst for the FBI. How I ended up here in the South, where I have the distinction of looking like what they still call a damn foreigner in most parts of Gerogia and sounding like a hick everywhere else in the world is a mystery Emily and Howard Street have never fully unraveled for me."
Keye Street is soon dragged into consulting on a serial killer case for the Atlanta homicide department. Pleanty of action and suspense with some humor from the creative ways she gets results as a process server, The Stranger You Seek is available at Hibbing Public Library.
