Text: Fidelman takes up with a prostitute in A Pimp's Revenge, a student confesses her hooker past in A Choice of Profession, a father trails after his streetwalker daughter in God's Wrath, a doctor imagines his neighbor as a semi-prostitute in the story In Retirement--it gets to be a little much.
Entailment: The stories contain prostitution as a major theme.
Contradiction: The stories all focus on a cat who lives in a monastery.
