Man with No Name- Double Tap

 The bounty hunter had his gun out and gripped by the barrel. He rested his elbow on the window sill, between the bars, holding the gun with the butt outward. The pair drew abreast of the window, the guard too preoccupied for caution.

  The hunter's arm whipped downward. There was a hollow thock! and the guard went down on his face. The twin knelt, then scrambled up again.

  "I've got his gun. That was beautifully done, Nameless. I'll meet you at the door."

  "Make it fast," the hunter said. "I couldn't get enough leverage to really bust his skull open."

  A moment later the door swung open and they crowded out. Dandy seized his daughter in a bear hug. The hunter dived around the corner of the cabin. There was another, louder, thock and he came back, holstering his gun.
