"I'll kill you," Barr said.
He broke off and launched a savage leap at Riddell. The knife flashed harmlessly through the air as Riddell sidestepped and grasped the other's arm. The two men locked together for a moment, and Riddell could see the hate in Barr's eyes.
The thud of flesh and bone felt good against his fists.
Suddenly he knew Barr had to die. Riddell had killed in the name of peace before.
He forced Barr back, twisting the wiry tyrant's arm until the knife dropped. Barr squirmed and clawed viciously, but Riddell held him.
They approached the balcony. "Don't!" Barr yelled.
Riddell felt utterly calm as he lifted the wriggling Barr and hurled him over the side of the balcony. A mighty roar went up.
