he turned about hastily and met the half smile on the lips of the new-comer, he realized instantly that his attitude had favored strongly of masculine vanity, and a not unbecoming flush mounted to his good-looking, straight-featured face. He had a sneaking sense of shame in being caught posing, as it were, before the mirror by this extremely pretty girl. She was more than pretty, this girl—she was rarely beautiful. She was of medium height and size, and her figure was symmetry itself, all its delicious curves and slender outlines defined at their best by the close-fitting black jersey waist she wore buttoned up to the graceful white throat that had a trick of holding itself high, as if innocently proud of the fair face that shone above it—the face that Captain Lancaster gazed at in wonder for a moment, and then in the most lively and decided disapprobation. For she was much too pretty to be a nurse, he said to himself—too pretty and too young. She had an air of[Pg 28] refinement quite above her position. She had an arch, pretty face, with beautiful blue-gray eyes that were almost black when the full white lids and dark lashes drooped over them. The dazzling fairness of her complexion was heightened by the unrelieved blackness of her dress, and her pouting lips by contrast looked like rosebuds. Two long, thick braids of lovely chestnut-brown hair hung down her back, and some soft, fluffy rings of the same color waved over the low, broad forehead with its slender, dark brows. She was not only beautiful, she looked bright and intelligent, and the half smile that parted her red lips now made her wonderfully lovely. [Pg 28] But pretty as she was, she was aware that Captain Lancaster was regarding her with knit brows and a general air of entire disapprobation. Perhaps it was a novel experience. It seemed to amuse her. The dimples deepened around the sweet, arch mouth. She looked down at the card in her hand, and began to read it aloud in a soft, hesitating, inquiring voice: "Cap-tain Lan-caster?" "Yes," he replied, and was on the point of making his most elegant bow when he suddenly remembered that it was not at all necessary to be so ceremonious with the nurse of his housekeeper's niece. So he straightened himself up again and said, almost tartly: "You are the baby's nurse, I presume?" The long fringe of the girl's lashes lifted a moment, and she flashed a dazzling glance into his face.
