Criminal

'Okay Mr. Hanson,' You reply.
He turned his back and walked down the stairs and headed to the reception desk.
Now was your chance. Now you could kill him and get away with it. But where would you stab him.
If you get him in between the shoulder blades, he will most likely stay alive but most likely become paralysed.
You could cut the back of his neck. He would probably scream in pain, but Probably will not die.
You could turn him around and stab him in the throat.
You could also pull out the sword that you hid, and cut off his head.
And the last option is, Stab him in the middle of his head.
