Duncan backed away from the advancing werewolf and backed into the motel room dresser. He fumbled as he stared at the snarling beast and opened a drawer.
Duncan pulled out a very large calibur handgun and pointed it at the werewolf's face.
The shewolf laughed secure in the belief that only silver could kill her.
Duncan pulled the trigger and shot right above the eyes and between where he knew the mass of her brain resided. The back of the werewolf's head exploded all over the motel room sending a shower of werewolf brains, skull, fur and skin on the carpet and walls behind her. The look on her face was priceless, the life in her eyes immediately went out and she slumped to the floor... dead, dead, dead!
"Yeah, it's silver in fairy tales BITCH!" Duncan snarled, "But this ain't no fairy tale, physics work and a Magnum of this size makes short work of assholes like you."
However, just to be absolutely sure, Duncan put three more rounds into her heart and went to his car to retrieve an ax which he used to hack off the bitche's head. Duncan was not anything if not prudent.
Unlike fairy tales, the dead werewolf didn't transform back into her human shape and when the police arrived, summoned by the motel owner who had heard the shots, they saw the remains of the dead bitch on the floor.
No murder charges were filed. After all, the beast was trying to kill him.
Duncan left after telling his incredible story, certain FBI investigators showed up and also questioned Duncan as was to be expected. Duncan was free to go and lived, just like in the fairy tales, happily ever after.
