The name echoed and reechoed through her mind: Paul Ellison. It should have been an illumination; instead, she had been thrust into utter darkness. Neither Arthur nor his mother had ever spoken of a brother, and she had known them for nearly ten years. Two men, who might be twin-brothers, with the same name: it was maddening. What could it mean? The beautiful white-haired mother, the handsome charming son, who idolized each other; and this adventurer, this outcast, this patient, brave and kindly outcast, with his funny parrakeet, what was he to them and they to him? It must be, it must be! They _were_ brothers. Nature, full of amazing freaks as she was, had not perpetrated this one without calling upon a single strain of blood. She lay back among her pillows, her eyes leveled at the few stars beyond her door, opened to admit any cooling breeze. Her head ached. It was like the computations of astronomers; to a certain extent the human mind could grasp the distances but could not comprehend them. It was more than chance. Chance alone had not brought him to the crumbling ledge. There was a strain of fatalism in Elsa. She was positive that all these things had been written long before and that she was to be used as the key. Paul Ellison. She drew from the past those salient recollections of Arthur and his mother: first, the day the two had called regarding the purchase of a house that her father had just put on the market,--a rambling old colonial affair, her own mother's birth-place. Sixteen: she had not quite been that, just free from her school-days in Italy. With the grand air of youth she had betrayed the fact almost instantly, while waiting for her father to come into the livingroom. "Italy!" said Arthur's mother, whom Elsa mentally adopted at once. The stranger spoke a single phrase, which Elsa answered in excellent if formal Italian. This led from one question to another. Mrs. Ellison turned out to be a schoolmate of her mother's, and she, Elsa, had inherited their very room. What more was needed? The Ellisons bought the house and lived quietly within it. Society, and there was a good deal of it in that small Kentuckian city, society waited for them to approach and apply for admittance, but waited in vain. Mrs. Ellison never went anywhere. Her son Arthur was a student and preferred his books. So eventually society introduced itself. Persons who ignored it must be interesting. When it became known that Mrs. Ellison had been the schoolmate of the beautiful and aristocratic wife of General Chetwood; when the local banker quietly spread the information that the Ellisons were comfortably supplied with stocks and bonds of a high order, society concluded that it could do very well without past history. That could come later.
