She gave the address of the _pension_ to the driver and vanished in the confusion. Sylvia fancied that this girl was lost forever, and wept to herself all the way home, but without shedding a single tear; her body was like fire. There was nobody about in the _pension_ when she arrived back; she dragged herself up to her room and lay down on the bed fully dressed. It seemed that all reality was collapsing fast, and she clutched the notes stuffed into her corsage as the only solid fact left to her, the only link between herself and home. Once or twice she vaguely wondered if she were really ill, but her mental state was so much worse than the physical pain that she struggled feebly to quieten her nerves and kept on trying to assure herself that her own unnatural excitement was nothing except the result of the unnatural excitement at the cabaret. She found herself wondering if she were going mad, and trying to piece together the links of the chain that would lead her to the explanation of this madness. "What could have made me go mad suddenly like this?" she kept moaning. It seemed that if she could only discover the cause of her madness she should be able to cure it. All her attention was soon taken up in watching little round red devils that kept rising out of the floor beside the bed, little round red devils that swelled and ripened like tomatoes, burst, and vanished. Her faculties concentrated upon discovering a reasonable explanation for such a queer occurrence; many explanations presented themselves, hovered upon the outskirts of her brain, and escaped before they could be stated. There was no doubt in Sylvia's mind that a reasonable explanation existed, and it was tantalizing never to be able to catch it, because it was quite certain that such an explanation would have been very interesting; at any rate, it was a relief to know that there was an explanation and that these devils were not figments of the imagination. As soon as she had settled that they had an objective existence, it became rather amusing to watch them; there was a new variety now that floated about the floor like bubbles before they burst.
