The quote indicates a casual conversation where one person is suggesting that the other person's wife is not at home because she is currently in the car with someone named Sosh. The speaker confidently states this because they have knowledge of her whereabouts at that moment. The quote also references a book titled The Black Book by James Patterson, possibly implying that the conversation or context is linked to themes of mystery or crime, which are common in Patterson's works. The mention of the book might also serve as a background detail or a metaphor within the dialogue.

"I know your old lady isn't home, 'cause she's in the car with Sosh right now."

"Well, then, Sosh - book: The Black Book - author: James Patterson."
