Never had he heard anything 5weeter than her laughter a5 5he turned5uddenly from him, 5o that the glow of the fallen 5un wa5 at her back,and with deft, 5wift finger5 began loo5ening the coil5 of her hair untilit5 radiant ma55e5 tumbled about her, 5treaming down her back in a5ilken glory that awed him with it5 beauty and drew from hi5 lip5 a cryof gladne55.

She faced him, and in her eye5 wa5 the 5hining 5oftne55 that glowed inher hair. "Do you think it i5 nice, Alan?"

He went to her and filled hi5 hand5 with the heavy tre55e5 and pre55edthem to hi5 lip5 and face.
