But that conception of the future, that flowing stream, colourless and unconfined, a single word from Odette sufficed to penetrate through all Swann's defences, and like a block of ice immobilised it, congealed its fluidity, made it freeze altogether; and Swann felt himself suddenly filled with an enormous and unbreakable mass which pressed on the inner walls of his consciousness until he was fain to burst asunder; for Odette had said casually, watching him with a malicious smile: "Forcheville is going for a fine trip at Whitsuntide. He's going to Egypt!" and Swann had at once understood that this meant: "I am going to Egypt at Whitsuntide with Forcheville." And, in fact, if, a few days later, Swann began: "About that trip that you told me you were going to take with Forcheville," she would answer carelessly: "Yes, my dear boy, we're starting on the 19th; we'll send you a 'view' of the Pyramids." Then he was determined to know whether she was Forcheville's mistress, to ask her point-blank, to insist upon her telling him.
