And then it happened. Tudor made his blunder. Never divining Joan's fluttering wildness, her blind hatred of restraint and compulsion, her abhorrence of mastery by another, and mistaking the warmth and enthusiasm in her eyes (aroused by his latest tale) for something tender and acquiescent, he drew her to him, laid a forcible detaining arm about her waist, and misapprehended her frantic revolt for an exhibition of maidenly reluctance. It occurred on the veranda, after breakfast, and Sheldon, within, pondering a Sydney wholesaler's catalogue and making up his orders for next steamer-day, heard the sharp exclamation of Joan, followed by the equally sharp impact of an open hand against a cheek. Jerking free from the arm that was all distasteful compulsion, Joan had slapped Tudor's face resoundingly and with far more vim and weight than when she had cuffed Gogoomy. Sheldon had half-started up, then controlled himself and sunk back in his chair, so that by the time Joan entered the door his composure was recovered. Her right forearm was clutched tightly in her left hand, while the white cheeks, centred with the spots of flaming red, reminded him of the time he had first seen her angry. "He hurt my arm," she blurted out, in reply to his look of inquiry. He smiled involuntarily. It was so like her, so like the boy she was, to come running to complain of the physical hurt which had been done her. She was certainly not a woman versed in the ways of man and in the ways of handling man. The resounding slap she had given Tudor seemed still echoing in Sheldon's ears, and as he looked at the girl before him crying out that her arm was hurt, his smile grew broader. It was the smile that did it, convicting Joan in her own eyes of the silliness of her cry and sending over her face the most amazing blush he had ever seen. Throat, cheeks, and forehead flamed with the rush of the shamed blood. "He--he--" she attempted to vindicate her deeper indignation, then whirled abruptly away and passed out the rear door and down the steps. Sheldon sat and mused. He was a trifle angry, and the more he dwelt upon the happening the angrier he grew. If it had been any woman except Joan it would have been amusing. But Joan was the last woman in the world to attempt to kiss forcibly. The thing smacked of the back stairs anyway--a sordid little comedy perhaps, but to have tried it on Joan was nothing less than sacrilege. The man should have had better sense. Then, too, Sheldon was personally aggrieved. He had been filched of something that he felt was almost his, and his lover's jealousy was rampant at thought of this forced familiarity. It was while in this mood that the screen door banged loudly behind the heels of Tudor, who strode into the room and paused before him. Sheldon was unprepared, though it was very apparent that the other was furious. "Well?" Tudor demanded defiantly. And on the instant speech rushed to Sheldon's lips.
