Thank you author for not completely abandoning Margaret to wallow in the misunderstanding, but I'm a little surprised she thinks the pair has any ability to hold financial information in their head.

Another instance where she's reading, but it's still "impossible" for her to communicate with her kidnappers. Would it kill the author to read Heterogeneous Linguistics?
