Catch 22 BY Heller, Joseph

The word appears 4 times.

This novel takes place during WWII and there is an incident at the airbase involving a man from Texas accused of being a racist.

"You murdered him," said Dunbar.

"You killed him," said Yossarian.

The Texan shrank back. "You fellas are crazy. I didn't even touch him."

"You murdered him," said Dunbar.

"I heard you kill him," said Yossarian.

"You killed him because he was a nigger," Dunbar said.

"You fellas are crazy," the Texan cried. "They don't allow niggers in here. They got a special place for niggers."

"The sergeant smuggled him in," Dunbar said.

"And you knew it."

Racial prejudice is a terrible thing, Yossarian. It really is. It's a terrible thing to treat a decent, loyal Indian like a nigger, kike, wop or spic. Cheif White Halfoat nodded slowly in conviction.
