You have your ways. You know people. A lot of people. You put the word out, asking around to find out who did this. But your people ain't talking. No answers for days, those low-lives, but you are still working the streets, walking the beat, wandering, drifting, always looking out for that little girl.
Oh! There she is!
All this seeking has made you lose your cool. You haven't sleep. Instead of taking the right-minded path and questioning her calmly, you set straight into shoving her against the wall, hard, and shaking her til her teeth rattle. She confesses: it's her junky dad! Ah HA!
But, oh, shit, said junky dad snuck up on you while you were being harsh with his daughter. He smashes your head in with the same pipe.
This time you don't survive the blow.
