  The airport is hella crowded, and of course every single face you see is pinched with anxiety, like flying home for Christmas is the most horrific event of their lives. You aren't usually one to use the word vibe, but the whole atmosphere gives you a slightly sick feeling, as if your body is absorbing their stress. 
  
  
   
  
  You board the plane for the six-hour flight to your connection, Atlanta. Halfway through, you use the lav.
  
  
   
  
  When you return, there's a postcard on your seat. This one shows a picture of the Empire State Building. You turn it over.
  
  
   
  
  Black, scrawling letters read:
  
  
   
  
  Dear Clara,
  
  
  When you get off, that’s when I’ll find you. 
  
  
  When I find you, that’s when I’ll kill you.
  
  
  When you run, better run fast.
  
  
  When you hide, better hide good.
  
  
  When you tell, it makes things worse.
  
  
   
  
  Panic clenches your throat. Is this real? Does someone actually want to kill you? 
  
  
   
  
  What should you do? Tell the stewardess? Or follow the advice on the postcard?
  > You don't Tell
   
  
  The plane lands.
  
  
   
  
  What should you do--go to the TSA and tell them what’s going on, or just run and hope the killer doesn’t find you?
