So easily and smoothly had Dempsey and the board done their preliminary work that many in the hall had not noticed the checking of the fascinating O’Sullivan’s social triumph. Among these was Maggie. She looked about for her escort.

“Smoke up!” said Rose Cassidy. “Wasn’t you on? Demps Donovan picked a scrap with your Lizzie-boy, and they’ve waltzed out to the slaughter room with him. How’s my hair look done up this way, Mag?”

Maggie laid a hand on the bosom of her cheesecloth waist.

“Gone to fight with Dempsey!” she said, breathlessly. “They’ve got to be stopped. Dempsey Donovan can’t fight him. Why, he’ll—he’ll kill him!”

“Ah, what do you care?” said Rosa. “Don’t some of ’em fight every hop?”

But Maggie was off, darting her zig-zag way through the maze of dancers. She burst through the rear door into the dark hall and then threw her solid shoulder against the door of the room of single combat. It gave way, and in the instant that she entered her eye caught the scene—the Board standing about with open watches; Dempsey Donovan in his shirt sleeves dancing, light-footed, with the wary grace of the modern pugilist, within easy reach of his adversary; Terry O’Sullivan standing with arms folded and a murderous look in his dark eyes. And without slacking the speed of her entrance she leaped forward with a scream—leaped in time to catch and hang upon the arm of O’Sullivan that was suddenly uplifted, and to whisk from it the long, bright stiletto that he had drawn from his bosom.

The knife fell and rang upon the floor. Cold steel drawn in the rooms of the Give and Take Association! Such a thing had never happened before. Every one stood motionless for a minute. Andy Geoghan kicked the stiletto with the toe of his shoe curiously, like an antiquarian who has come upon some ancient weapon unknown to his learning.

And then O’Sullivan hissed something unintelligible between his teeth. Dempsey and the board exchanged looks. And then Dempsey looked at O’Sullivan without anger, as one looks at a stray dog, and nodded his head in the direction of the door.

“The back stairs, Giuseppi,” he said, briefly. “Somebody’ll pitch your hat down after you.”

Maggie walked up to Dempsey Donovan. There was a brilliant spot of red in her cheeks, down which slow tears were running. But she looked him bravely in the eye.
