You spin around the corner and slash high. You feel as your knife cuts through something. You hear a thud and look down. Before your feet is a tall crumpled-up man. He seemed to be, at one time, holding 2 knives which are now sprawled across the floor. There is a deep cut on his neck. He is dead.
As you pick up his knives, the thing turns the corner. It seems pleased. "Good job, now follow me."
You stuff the knives in your waistband as you watch him walk away.
