The Big Fix by Roger L. Simon (Warner Books 1973)

"Mr. Seymour Bittleman - you should pardon the expression - has made a ridiculous misinterpretation of history," she told the boys as they climbed onto her lap. "After seventy years of struggle, he now announces that Kautsky was correct at the Second International . . . Vey es Mir! . . . Don't you remember what Trotsky wrote in 'A Letter to Party Meetings,' that the Kautskian line leads to nothing but revisionism and Social Democracy?!"
"The rabbi of Kotzk said: Everything in the world can be imitated except truth. For truth that is imitated is no longer truth." Bittelman grinned and stabbed a piece of coldfish with his fork.
"Now what the hell does that mean?" She tugged at her babushka and made a face somewhere between Ethel Merman and La Pasionaria.
"The rabbi of Ger said: I often hear men say they want to throw up the world. But I ask you, is the world yours to throw up?"
"Shut up, Bittleman. I don't want you polluting these children's minds with your cheap religious talk. Next thing you know you'll be putting on a prayer shawl and quoting Hillel."
She turned away from him with a wave and I opened the lunch in front of us. Bittelman snickered and tucked a tiny napkin into his white shirt already stained with fish oil.

Garnethill by Denise Mina (Carroll & Graf Mystery 1998)

"Marie was the eldest. She moved to London in the early eighties to get away from her mum's drinking, settled there and became one of Mrs Thatcher's starry-eyed children. She got a job in a bank and worked her way up. At first the change in her seemed superficial: she began to define all her friends by how big their mortgage was and what kind of car they drove. It took a while for them to realize that Marie was deep down different. They could talk about Winnie's alcoholism, about Maureen's mental-health problems, and to a lesser extent about Liam dealing drugs, but they couldn't talk about Marie being a Thatcherite. There was nothing kind to be said about that. Maureen had always assumed that Marie was a socialist because she was kind. The final breal between them came the last time Marie was home for a visit. They were talking about homelessness and Maureen ruined the dinner for everybody by losing the place and shouting, 'Get a fucking value system,' at her sister."
