A village intelligence service
Caroline learns of Mrs. Ferrars’s death from the household’s social network before Dr. James Sheppard can keep the news private.

The hidden arrival
Caroline knows Ralph Paton is staying at The Three Boars and has seen him with a young woman. She tells Ackroyd, who had claimed Ralph was in London.
A theory takes shape
Her overheard conversation in the wood reveals Ralph’s fear of being cut off financially. The information helps explain his apparent motive, even though Caroline cannot identify the woman.

Suspicions multiply
Caroline develops theories about Parker, Miss Russell, Flora, and Ralph, often treating hunches as conclusions. Her certainty supplies a comic counterpoint to the police inquiry.

An answer without context
