And just as she was going to speak, the front door was opened and Rosa appeared. Sabine withdrew her hand from Christophe's and went hurriedly into her house. At the door she turned and looked at him once more--and disappeared. * * * * * Christophe thought he should see her again in the evening. But he was watched by the Vogels, and followed everywhere by his mother: as usual, he was behindhand with his preparations for his journey and could not find time to leave the house for a moment. Next day he left very early. As he passed Sabine's door he longed to go in, to tap at the window: it hurt him to leave her without saying good-bye: for he had been interrupted by Rosa before he had had time to do so. But he thought she must be asleep and would be cross with him if he woke her up. And then, what could he say to her? It was too late now to abandon his journey: and what if she were to ask him to do so?... He did not admit to himself that he was not averse to exercising his power over her,--if need be, causing her a little pain.... He did not take seriously the grief that his departure brought Sabine: and he thought that his short absence would increase the tenderness which, perhaps, she had for him. He ran to the station. In spite of everything he was a little remorseful. But as soon as the train had started it was all forgotten. There was youth in his heart. Gaily he saluted the old town with its roofs and towers rosy under the sun: and with the carelessness of those who are departing he said good-bye to those whom he was leaving, and thought no more of them. The whole time that he was at Düsseldorf and Cologne Sabine never once recurred to his mind. Taken up from morning till night with rehearsals and concerts, dinners and talk, busied with a thousand and one new things and the pride and satisfaction of his success he had no time for recollection. Once only, on the fifth night after he left home, he woke suddenly after a dream and knew that he had been thinking of _her_ in his sleep and that the thought of _her_ had wakened him up: but he could not remember how he had been thinking of her. He was unhappy and feverish. It was not surprising: he had been playing at a concert that evening, and when he left the hall he had been dragged off to a supper at which he had drunk several glasses of champagne. He could not sleep and got up. He was obsessed by a musical idea. He pretended that it was that which had broken in upon his sleep and he wrote it down. As he read through it he was astonished to see how sad it was. There was no sadness in him when he wrote: at least, so he thought. But he remembered that on other occasions when he had been sad he had only been able to write joyous music, so gay that it offended his mood. He gave no more thought to it. He was used to the surprises of his mind world without ever being able to understand them. He went to sleep at once, and knew no more until the next morning.
