He bowed quietly, showing a slight surprise, as he might have done at the remark of a stranger. Then he turned to the door. "I am sorry to have interrupted you," he said. "Good-morning." When the door closed upon him Mariana stood for an instant with her head bent as if listening to his footsteps on the stairs. Then she turned to Nevins, a smile flashing across her face. "We must go back to the portrait," she said. "It must be finished quickly--quickly. I am afraid of wrinkles." CHAPTER IX Mariana was walking under the elms that skirt the park on Fifth Avenue. It was a mild December morning, and the sunshine fell in silvery waves through the bare branches of trees overhead and rippled lightly across the concrete sidewalk, while the slender shadows of the boughs assumed the effect of irregular lines drawn by crude fingers upon a slate. Far ahead, through the narrowing archway of naked elms, the perspective sloped in gradual incline, blending the changing shades of blue and gray into a vista of pale violet. On the low stone wall to her left the creepers showed occasional splashes of scarlet berries, glowing warm and vivid through the autumnal haze which tinted the atmosphere. December had reverted for a single day into the majesty of dead October. Mariana walked slowly, the furs, which she found oppressive, open at the throat, and her muff hanging idly from her hand. There was a rapt expression upon her face, and her eyes were sombre. She had the strained and preoccupied air of one whose mind has winged back to long-past days, leaving the body adrift in its relation to present events. All at once a tiny child, rolling a toy along the sidewalk, stumbled and fell before her feet, uttering shrieks of dismay. The incident recalled her to herself, and, as she stooped to lift it, she smiled at the profuse apologies of the nurse. Then she glanced about her, as if uncertain of the number of blocks that she had walked.
