These moods, as Larson well knew, were occasioned by Miss Conway’s treatment of Jim. Her influence over McKay seemed as unlimited as it was magical. Larson had tried to reason with Jim, and had tried to convince him that Miss Conway did not care seriously for him or any one else except herself. But all his efforts produced no other effect than to kindle new passion in McKay.

On the evening mentioned, McKay had asked permission to call at her home, but was refused, she pleading a previous engagement. For some unknown reason (the guiding hand of fate, for those who believe in fate), he walked out to her home, and as he drew near he saw Larson—his old pal, Bill Larson—enter the home of Miss Conway!

For a moment he stood as if stunned. Of all persons, Bill was the last he would have suspected.

Then it all became plain to him—Bill had tried to alienate the girl’s love!

Slowly, listlessly, McKay turned and retraced his steps to his room. He sat there a long while in the dark and let his mind become polluted with the poison of an insane jealousy, while he saturated his system and dulled his conscience with whisky.

About eleven he rose, placed a gun in his pocket, and started for the hotel where he and Larson often met in the evening. As he walked, his mind became closed to reason, closed to his regard for his friend, closed to everything except that Larson had double-crossed him. As he sat and waited in the barroom his brain focused itself on this one point until it had taken possession of him.

He had been there about a half hour when Larson appeared, laughing and chatting with some friends. Bill was in great spirits, for he had accomplished, that night, the thing he had long sought. Miss Conway had been very reasonable and had promised that she would cause McKay no more anxiety.

McFadden and a few others hastened at once toward him to tell him about McKay. But they were too late, for Larson, espying McKay, sang out:

“Hello, Jim, old scout! Come over and ‘hist’ one with us!”

McKay jumped up and strode over to the bar, his eyes glittering and his mouth twitching with hatred.
