Part 2

Slowly, Riddell advanced across the room toward him, while the noise from below grew deafening. As he approached Barr, the small man suddenly whipped a knife from his jacket and circled around Riddell.

"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.

[Illustration: 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.

He knew he had committed no crime, it was an execution, rather. Barr was dead, and with his death another enemy of peace had perished.
