It was at this critical moment that Cassidy entered from the opposite side of the office. As his eyes fell on the girl at the door across from him, his stolid face lighted in a grin. And, in that same instant of recognition between the two, the color went out of the girl's face. The little red lips snapped together in a line of supreme disgust against this vicissitude of fate after all her manoeuverings in the face of the enemy. She stood motionless in wordless dismay, impotent before this disaster forced on her by untoward chance.

“Hello, Aggie!” the detective remarked, with a smirk, while the Inspector stared from one to the other with rounded eyes of wonder, and his jaw dropped from the stark surprise of this new development.

The girl returned deliberately to the chair she had occupied through the interview with the Inspector, and dropped into it weakly. Her form rested there limply now, and the blue eyes stared disconsolately at the blank wall before her. She realized that fate had decreed defeat for her in the game. It was after a minute of silence in which the two men sat staring that at last she spoke with a savage wrath against the pit into which she had fallen after her arduous efforts.

“Ain't that the damnedest luck!”

For a little interval still, Burke turned his glances from the girl to Cassidy, and then back again to the girl, who sat immobile with her blue eyes steadfastly fixed on the wall. The police official was, in truth, totally bewildered. Here was inexplicable mystery. Finally, he addressed the detective curtly.

“Cassidy, do you know this woman?”

“Sure, I do!” came the placid answer. He went on to explain with the direct brevity of his kind. “She's little Aggie Lynch—con' woman, from Buffalo—two years for blackmail—did her time at Burnsing.”

With this succinct narrative concerning the girl who sat mute and motionless in the chair with her eyes fast on the wall, Cassidy relapsed into silence, during which he stared rather perplexedly at his chief, who seemed to be in the throes of unusual emotion. As the detective expressed it in his own vernacular: For the first time in his experience, the Inspector appeared to be actually “rattled.”

For a little time, there was silence, the while Burke sat staring at the averted face of the girl. His expression was that of one who has just undergone a soul-stirring shock. Then, presently, he set his features grimly, rose from his chair, and walked to a position directly in the front of the girl, who still refused to look in his direction.

“Young woman——” he began, severely. Then, of a sudden he laughed. “You picked the right business, all right, all right!” he said, with a certain enthusiasm. He laughed aloud until his eyes were only slits, and his ample paunch trembled vehemently.
