His soft voice had that fluid quality which percolates everywhere. He meant to be polite, nothing more; he wished to thank a pretty girl who had nursed a brother: but to Mary his words had other significance; his glance became an indictment, his tone inquisitorial. Without reason, her cheeks flamed. Archibald turned aside, murmuring a commonplace. When he looked at her, after a discreet interval, she was composed but pale. She went out of the room and did not return.

"Um!" said Archibald to himself, "I must speak to Betty about this."

Not, however, till late did he find an opportunity. Harry Kirtling was dining in Cadogan Place, and loath to say good-night. The young fellow had crushed a muscle of his leg out hunting, and had come up to London to see a famous surgeon, who prescribed gentle walking exercise and massage. Harry complained bitterly of the hardship of spending a fortnight away from his kennels, but was consoled by Betty, who promised to entertain him. Despite his injury, he looked astonishingly well, and brought with him from Cumberland a breezy atmosphere of mountain and moor which Betty inhaled gratefully. He had managed to make it plain that he was still her devoted slave—a tribute which the best of women accept without scruple. And he had asked her advice upon a score of matters connected with Kirtling.

When Harry had taken his clean, lean body out of her drawing-room, Betty turned rather impatiently to Archibald.

"Has anything happened? You have been so glum. Surely you do not resent my asking Harry to dine without consulting you?"

"Harry?" His tone was heavily contemptuous. "Harry can waste as much of your time as you like to give him. Yes; something has happened."

He told his story.

"I don't believe it."

"The girl is attractive. Her mother, I am told, reckons herself a lady. Something must be done. I give you my word that I am not mistaken."

"I don't believe it," Betty repeated.
