She is furious to be so accused, and deeply shocked. Poirot is equally shocked, because he too has never heard of any Barnabas Pandy, and he certainly did not send the letter in question. He cannot convince Sylvia Rule of his innocence, however, and she marches away in a rage.Shaken, Poirot goes inside, only to find that he has a visitor waiting for him a man called John McCrodden who also claims also to have received a letter from Poirot that morning, accusing him of the murder of Barnabas Pandy.

Figure of speech, any intentional deviation from literal statement or common usage that emphasizes, clarifies, or embellishes both written and spoken language. Forming an integral part of language, figures of speech are found in oral literatures as well as in polished poetry and prose and in everyday speech. Greeting-card rhymes, advertising slogans, newspaper headlines, the captions of cartoons, and the mottoes of families and institutions often use figures of speech, generally for humorous, mnemonic, or eye-catching purposes. The argots of sports, jazz, business, politics, or any specialized groups abound in figurative language.
