Criminal

You pull out your blade and wait for the Landlord to get to the bottom of the stairs. Here you jump from a higher point than the Lanmdlord and us you get above his head, you throw the knife, full force, into Mr. Hansons head.
You land on the ground a few feet in front of Mr. Hanson.
As you stand up you watch the Landlord feel his head. Here his eyes go wide as he realises what has just happened. Then he begins to sway.
