At the instant a step on the porch interrupted them. Marian, already repentant, sprang from Mason's encircling arms and turned to see Gardner coming toward them. He had wandered about the grounds miserably after they had parted and had returned to sue for pardon, but what he had just seen had changed his mind. His face was convulsed with passion. Disregarding Marian, he stepped toward Mason, his hand upraised as if he would strike him down. There was murder in his heart. The girl screamed and then turned and fled in dismay. She had broken her engagement with a man whom she now realized she loved with all her heart, and she had promised herself to a man whom she knew she did not love. She had been bitterly unjust, in her folly, to both men.

The dancing for the evening was already over. The women of the party were retiring to their rooms, and Marian, sick at heart, slipped away and sought her chamber also. Throwing herself dressed upon her bed, she thought it over. Nothing would happen until the morning, she reasoned, and then she would make a clean breast of it to her father. He would extricate her from her difficulties.

Mason on the porch was already master of himself.

"Don't strike me!" he said to Gardner, "or I shall kill you where you stand! Besides, 'tis not necessary. I understand your feelings and I intend to give you satisfaction, but the cause of our quarrel must not be known. The reputation of the woman—I intend to make my wife must not be the subject of public comment. Control yourself, sir, I beg of you," he added, smiling triumphantly, as the other stamped his foot. "Let us repair to the house. The ladies will have retired, and we can easily manufacture sufficient public cause for a quarrel. I will take it upon myself. Come no nearer!" he said, thrusting his hand into the pocket of his coat as Gardner swayed toward him. "I warn you that I am armed. On my word, I will shoot you like a mad dog! I will submit to nothing from you. I am giving you a chance for your life and affording you every satisfaction as it is."

Gardner controlled himself with a mighty effort.

"You are right," he gasped; "'tis not through fear that I do not strike you, but, as you say, Miss Fletcher's name must not become the subject of gossip. You shall never marry her! I intend to kill you!"

"That's as may be," answered the other; "let us not come to blows about it. I am not used to such. 'Tis vulgar brawling. Control yourself. I take your arm, so. Though 'tis hateful to both of us, we must appear to be on friendly terms."

Arm in arm the two rivals entered the hall and no one dreamed of the deadly hatred which sundered them. After the departure of the women Colonel Fletcher and his guests sat down to spend the rest of the evening—morning rather—between cards and the bottle. Chance, or their own contrivance, made Mason and Gardner partners. Neither of the two partook of the wine. As the heat of Gardner's passion abated, he realized the necessity for acquiring his wonted calmness. He was a famous shot with the pistol, a weapon with which Mason was not so familiar, and he believed that if he had an opportunity he could kill him. He fully intended to do so.

It was an age in which duels were common and life was cheap. Mason was to afford the provocation and give the challenge. He said he would do so and he was a man of his word. Then, as the challenged party, Gardner would have the choice of weapons. As the game proceeded, Mason, who had made several irritating remarks upon his partner's playing, finally remarked, sneeringly:

"That's a cowardly deal, Gardner. Why don't you play more boldly, sir?"
