i 'm charging at him and he 's throwing himself at me and i 'm holding the knife but at the last second , i leap to the side , letting him slam hard into the wall- he whirls around , face in a snarl , swinging an arm round to hit me and i duck and slash at it with the knife , cutting across his forearm , and it do n't even slow him down- and he 's swinging at me with his other arm and he 's catching me just under the jaw- knocking me back- `` todd !
