Swann had read quite plainly at the beginning of the line "I was right," but did not understand what Odette had been right in doing, until suddenly a word which he had not been able, at first, to decipher, came to light and made the whole sentence intelligible: "I was right to open the door; it was my uncle." To open the door! Then Forcheville had been there when Swann rang the bell, and she had sent him away; hence the sound that Swann had heard.
