William Somerset: Ernest Hemingway once wrote that the Earth is a fine place and is worth fighting for. I agree with the second part.
When Somerset goes back to the man's house alone, he cuts a sticker on the door with his switch-blade to get in. The first error is the sticker is on the inside and it says "Keep Out." The best part about it is the door opens inward. How did they put the sticker on the inside and then exit?
