Maggie laid a hand on the bosom of her cheese-cloth 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 zigzag 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 arm 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.

“I knew it, Dempsey,” she said, as her eyes grew dull even in their tears. “I knew he was a Guinea. His name’s Tony Spinelli. I hurried in when they told me you and him was scrappin’. Them Guineas always carries knives. But you don’t understand, Dempsey. I never had a fellow in my life. I got tired of comin’ with Anna and Jimmy every night, so I fixed it with him to call himself O’Sullivan, and brought him along. I knew there’d be nothin’ doin’ for him if he came as a Dago. I guess I’ll resign from the club now.”

Dempsey turned to Andy Geoghan.

“Chuck that cheese slicer out of the window,” he said, “and tell ’em inside that Mr. O’Sullivan has had a telephone message to go down to Tammany Hall.”

And then he turned back to Maggie.

“Say, Mag,” he said, “I’ll see you home. And how about next Saturday night? Will you come to the hop with me if I call around for you?”

It was remarkable how quickly Maggie’s eyes could change from dull to a shining brown.

“With you, Dempsey?” she stammered. “Say—will a duck swim?”
