Then her answer and her question: Was Chrystie there? That smoothed out the crossness and woke him up. He became suddenly alert: "Chrystie? Here--with us?" "Yes--staying over till Friday. Went down this afternoon." "No. _She's _not here. What makes you think she is?" She did not know what to say; the instinct to protect her sister was part of her being, strong in a moral menace as a physical. She fumbled out an explanation--she'd been out of town and in her absence Chrystie had gone to the country without leaving word where. It was all right of course, she was a fool to bother about it, but she couldn't rest till she knew where the girl had gone. It was probably either to the Spencers or the Joneses; they'd been teasing her to visit them all winter. Roy, now wide-awake, showed a tendency to ask questions, but she cut him off, swamped his curiosity in apologies and good-bys and hung up the receiver. She was almost certain now, and again she stood pressing down her terrors, urging her faculties to intelligent action. She did not let them slip from her guidance; held them close as dogs to the trail. A moment of rigid immobility and she had whirled back to the telephone and called up a near-by livery stable. This answered promptly and she ordered a cab sent round at once. While she waited she tried to keep steady and think clearly. Prominent in her mind was the necessity not to move rashly, not to do anything that would react on Chrystie. There might yet be a mistake--a blessed, unforseen mistake. She clung to the idea as those about a deathbed cling to the hope that a miracle may supervene and save their loved one. There _was_ a possibility that Chrystie had gone on some mysterious adventure of her own, was playing a trick, was doing anything but eloping with a man that no one had ever thought she cared for. The only way to find out whether Mayer had any part in her disappearance was to go directly to him. She sat stiffly in the cab holding her hands tight-clenched to control their trembling. Her whole being seemed to tremble like a substance strained to the point of a perpetual vibration. She was not conscious of it; was only conscious of her will stretching out like a tangible thing, grasping at a fleeing Chrystie and dragging her back. And under that lay a substratum of anguish--that it was _her_ fault, _her_ fault. The wheels repeated the words in their rhythmic rotation; the horse's hoofs hammered them out on the pavement.
