“It’s a friend of mine, Mr. Baldwin, a new boarder here. Mr. McMurdo, may I introduce you to Mr. Baldwin?”

The young men nodded in surly fashion to each other.

“Maybe Miss Ettie has told you how it is with us?” said Baldwin.

“I didn’t understand that there was any relation between you.”

“Didn’t you? Well, you can understand it now. You can take it from me that this young lady is mine, and you’ll find it a very fine evening for a walk.”

“Thank you, I am in no humour for a walk.”

“Aren’t you?” The man’s savage eyes were blazing with anger. “Maybe you are in a humour for a fight, Mr. Boarder!”

“That I am!” cried McMurdo, springing to his feet. “You never said a more welcome word.”

“For God’s sake, Jack! Oh, for God’s sake!” cried poor, distracted Ettie. “Oh, Jack, Jack, he will hurt you!”

“Oh, it’s Jack, is it?” said Baldwin with an oath. “You’ve come to that already, have you?”

“Oh, Ted, be reasonable—be kind! For my sake, Ted, if ever you loved me, be big-hearted and forgiving!”

“I think, Ettie, that if you were to leave us alone we could get this thing settled,” said McMurdo quietly. “Or maybe, Mr. Baldwin, you will take a turn down the street with me. It’s a fine evening, and there’s some open ground beyond the next block.”

“I’ll get even with you without needing to dirty my hands,” said his enemy. “You’ll wish you had never set foot in this house before I am through with you!”

“No time like the present,” cried McMurdo.

“I’ll choose my own time, mister. You can leave the time to me. See here!” He suddenly rolled up his sleeve and showed upon his forearm a peculiar sign which appeared to have been branded there. It was a circle with a triangle within it. “D’you know what that means?”

“I neither know nor care!”

“Well, you will know, I’ll promise you that. You won’t be much older, either. Perhaps Miss Ettie can tell you something about it. As to you, Ettie, you’ll come back to me on your knees—d’ye hear, girl?—on your knees—and then I’ll tell you what your punishment may be. You’ve sowed—and by the Lord, I’ll see that you reap!” He glanced at them both in fury. Then he turned upon his heel, and an instant later the outer door had banged behind him.

For a few moments McMurdo and the girl stood in silence. Then she threw her arms around him.

“Oh, Jack, how brave you were! But it is no use, you must fly! To-night—Jack—to-night! It’s your only hope. He will have your life. I read it in his horrible eyes. What chance have you against a dozen of them, with Boss McGinty and all the power of the lodge behind them?”
