For a moment Bat Scanlon stood as one petrified; there was Nora, beautiful Nora Cavanaugh, the yellow light in the meshes of the glorious bronze hair, the splendid figure held tense and quivering, the revolver in her hand and her face turned toward the two men. Then he exhaled a long breath, and wiped the drops of perspiration from his face.

"It's Nora, all right," he whispered. "It's Nora! But what in the name of the seven staggering Siwashes is she doing here? What does she——?" he paused abruptly, his eyes still upon her. With the revolver held tight she crept stealthily toward Big Slim and the Swiss. The breath drew hard in Bat's throat as he proceeded. "But why bother to ask what she's doing? If I ever saw a person's meaning spelled out in full by the actions, here is the time. Those two guys at the table have only another second or two, and then they are due for the surprise of their lives."

But just when it seemed as though the girl could reach out her hand and touch either of the two, she stopped. To Bat's surprise she sank down upon her knees, turned her head sideways, and was motionless.

"What's that?" demanded Bat, whisperingly, his eyes wide open. "What's she doing?"

But even while the words were still in his mouth he sensed the meaning of the thing; shifting his position to the other window he saw that the illuminated windows below belonged to different rooms; there was a wall between Nora and the two men, and it was at this she was kneeling, one ear held to it, listening.

"Ah!" said Bat. "That's it, eh? Good! Things are not to go off with the excited bang I expected. I'll have at least a couple of minutes to get myself in hand."

His first thought was of the big Colt which hung under his arm; a touch assured him that it was still there and free. His next was as to the lay of the land; to reach the main floor was simple enough; but how to get to the rooms in which were Nora and the two men was another matter. As he weighed the situation anxiously, an idea occurred to him. While looking along the hall a while before he had seen a small red light burning.

"Why, of course," he said. "A fire-escape. Just the thing. It's sure to lead down into this courtyard; and from there it's only a step and a smash, and I'm in and asking them about this little matter."

Quietly he opened the door and stepped into the hall. The red light burned over a window some dozen feet away; he lifted the sash and in a moment was out upon the platform. Below, all was darkness, save for the light which came from the two windows he had been watching; and down into this shadowy gulf went Bat with careful steps.

The courtyard was paved with the uneven stones of another day, and gingerly Bat picked his way across it toward the light. This was thrown out in two wide shafts, which met and merged in the first dozen feet of their projection.

"I must hang around on the edge," Bat reflected. "If I dip into the light they'll see me before I'm ready to have them do so."

Craftily he approached the window through which he had seen Nora, and looked in. She was still there, but was now erect, talking with some one whom Bat could not see. She stood with her back to the window, her hands behind her; the revolver was still held in one of them, and while she was in this position, she placed it upon the stand.

"Clever work," said Bat, as he watched and saw the manoeuvre successfully accomplished. "Disarming in the face of the enemy, and the said enemy never the wiser. But I wonder why the armament is not now necessary, and was so much so five minutes ago?"

He shifted a little, taking a chance of being seen in the streaming window lights. The person to whom Nora was talking was Big Slim. The burglar leaned upon the tall back of a chair with his elbows; his hands propped his chin, and he was steadfastly watching the girl and listening to what she said. And the Nora whom Bat now saw was greatly changed from the cautiously moving, fearfully listening creature of only a little while before.

"She's laughing," said Scanlon, amazed. "Laughing!"

She was; with her splendid head thrown back, her teeth shining white as milk. And then, as she spoke to the lank desperado before her, there were little ripples of amusement in her face; her hands gestured as though in mockery. But all this won no reflection in the cadaverous mask of the burglar; his shifty, green-colored eyes were as hard as stone, and as pitiless. He changed his position and began to speak; his utterances seemed slow and emotionless. His whole manner was of disbelief; time and again he seemed to strike at the same point; and Bat finally realized that he was charging the girl with something. But she stood before him, the look of amusement still in her face, her beautiful teeth gleaming when she laughed.

Finally with a sweep of his hand, Big Slim overset the chair, and with rigid anger in his hollow face moved toward her. The big Colt left its holster and appeared in Scanlon's hand. In the lanky gentleman's career as a housebreaker he had, doubtless, had many narrow shaves; but never had he stood so close to death as he did at that moment. And it was the girl who saved him.

With a gesture of amused contempt, she waved him back; turning, she took a wrap from a chair and threw it about her. Then with another motion—one of command—she stood facing him.

"She's telling him to open the door," said Bat "And," amazedly, "by George, he's doing it!"

For the tall figure of Big Slim disappeared into a part of the room outside Bat's vision. And now for the first time since he had seen her shadow crossing the wall, Nora Cavanaugh hesitated. For a flashing instant the watcher got a full view of her face as it was held away from the burglar. The laughter was gone; in its place was fear—pale, dumb fear; the hands which fumbled with the wrap were purposeless, with no direction. And then she, too, disappeared out of the range of the watcher's vision.

Disregarding all thought of possible detection, Scanlon now approached the window in the full glare of the light. He saw a door in the room standing open, and through this Nora was passing. Then the burglar pulled it shut and the place was a blank. Bat considered for only an instant as to what was best to do. His strong fingers gripped at the sash, and to his satisfaction and gratification it slid upward; with a pull he had lifted his heavy body upon the sill and was in the room. His steps were soft and long as he moved toward the door through which the two had just gone; his hand was reaching out for the knob when he saw it turning slowly. He shrank away intuitively, and against the wall, while the door opened with him behind it. He heard a hesitating sort of breathing, and then a step within the room. Around the edge of the door Bat could see the gas branch as it projected from the wall; a hand appeared and turned off the light, then the footsteps sounded once more, leaving the room, and the door closed as softly as it had opened.

Bat waited for a few moments, and then, under his hand, the door opened, and he looked out. There was a short and rather wide hall, and at the far end was a door which instantly suggested itself as the one leading to the street. And that was not all. At the door, holding it open about an inch, was old Bohlmier, and he was furtively peering out.

"He was the party who turned off the light," said Bat, as he drew the door to and stood waiting.

In a little while there was a faint click which told that the street door had been closed; then Bat heard the old Swiss enter the room adjoining—the one in which the athlete had seen him from above. With careful steps Scanlon went down the short hall, and slipped back the lock. Peering out he saw a narrow street, and a taxi standing at the curb. In this was Nora Cavanaugh, and beside it stood Big Slim. Scanlon saw Nora perfectly, for the street light shone full upon her; once more she was smiling, once more her head was thrown back in amusement. The attitude of the burglar was threatening, his big bony hands clutched the door frame of the cab, and his shoulders were rounded doggedly.

"Laugh!" Bat heard him say, "laugh all you like. But as long as you do the rest of it, I don't care. So, get busy, and I'll be waiting to hear from you."

With this he stepped back and the girl signaled the driver. The cab started away and Big Slim turned toward the door. Swiftly Bat left it, and was back in the room from which he had entered the hall; dropping quietly out of the window, he crossed the courtyard and scaled the fire-escape. Then, once more in his own room, he sat upon the edge of the bed.

"Well," said he, "the new one is here. I felt sure it was coming; but," and he gripped the edge of the iron cot hard, "I never expected it to be anything like this."
