I order another bourbon, neat. This is the drink that will flip the switch. I don’t even know how I got here, to this place, to this point. Something is happening to me lately. I’m drinking too much. My sheets are soaking wet when I wake up from nightmares of decaying corpses. I order another drink and swig it, trying to forget about the latest case I can’t shake. Crime solving for me is more complex than the challenge of the hunt, or the process of piecing together a scientific puzzle. The thought of good people suffering drives me to the point of obsession.
