But as Mollie spoke Kitty perceived that she had never glanced at the fashionable dress. She only saw the soul in the bright eyes and the happy smile round the lips. Gavon's voice calling them was heard from below. They ran downstairs.
When they appeared, Captain Keith glanced from one sister to the other. He was dimly conscious that a change, and that not exactly for the better, had come over Mollie, and that Kitty looked, as she always did, the perfection of charm. Nevertheless, the expression in Mollie's eyes and the tone of her voice continued to arouse that strange, delicious foreign feeling in his breast. He found that he liked to touch her hand, and that he also liked to look into her brown eyes. He was not yet aware of his own sensations. He only thought,—
"I am but tracing the extraordinary likeness and the extraordinary difference between these two girls. Of course I know Kitty's dear little phiz, and Mollie's is almost the same, feature for feature, and yet there never were any two girls who have less in common."
The three arrived at St. James's Hall in good time. Gavon secured seats for his party, and they soon found themselves listening to a fine concert. Mollie had a passion for music, and as she sat now and allowed it to fill both heart and soul, her eyes kindled, and the colour came rich and deep into her cheeks. Gavon continued to watch her almost stealthily. Kitty chatted whenever she could find a moment to give her gay little voice a chance of being heard. Gavon sat between the two; he answered Kitty, and talked with her, scolding her now and then, and desiring her on many occasions to "hush," "not to make so much noise," to "behave herself," and much more to the same effect. As long as he spoke to her at all, poor Kitty was in the seventh heaven of bliss. From her present position she could not see how often he glanced at Mollie, and fancied that her little stratagem to make her sister not look quite at her best was bringing the most satisfactory results.
The first half of the concert was over, when a man pushed his way along the line of people and dropped into a seat by Kitty's side. She uttered an exclamation, half of annoyance and half of pleasure.
"How do you do, Miss Hepworth?" he said. "I have not seen you for a very long time.—Ah, Keith, how are you?"
"I did not know you were in London, Major Strause," answered the girl.
"London is practically empty; but, all the same, this war news is bringing many of us up," he replied.
Mollie looked round to see what the newcomer was like. She noticed a somewhat thick-set man, with reddish hair and a very long moustache. His eyes were of a light blue. His face was considerably freckled. Mollie voted him at once commonplace and uninteresting, and would not have bestowed any further thought upon him had she not observed a curious change in Keith's appearance. His face turned first white, then stern and sombre. He ceased to talk to Kitty, who was devoting herself now, with all that propensity for flirting which was part of her nature, to Major Strause.
"Do you know him well?" asked Mollie suddenly, in a low tone.
