St George pushing Captain Freedom

George pushed out his hand to shove Freedom in the chest. It wasn’t a particularly fast or skilled move. It made Freedom think of Combatives training. His own arm dropped down for an easy block, and he started thinking of ways to politely throw the couple back out on the street.
George’s hand pushed past the block. It was like trying to stop a moving truck. Or a tank. Freedom had just enough time to remember how the man had held the steel-lined case up over his head and then George’s palm connected with his sternum.
The front door flew away, the office blurred, and something slammed into Freedom’s back just before he heard wood crack and splinter behind him. He found his footing and glanced over his shoulder. His desk had been crushed between his back and the far wall of the office.
George stood a dozen feet away with his hand out.
