"A bomb!" cried Josie, stepping from her retreat and confronting them. "A bomb with the fuse lighted, and timed to blow up this building after you had gone away, Mr. Colton. That man before you is a German spy, and I arrest him in the name of the law. Put up your hands, Abe Kauffman!"
The little revolver was in her hand, steadily covering him. Kauffman gave an amused laugh, but he slowly raised his arms, as commanded.
"I don't quite understand," said the puzzled manager, looking from one to the other.
"Well, I brought the new projectile, Colton, as I had agreed," answered the German, coolly, "but your quaint watchman has thrown it away. As for the girl," he added, with a broad grin, "she has fooled me. She said she had brains, and I find she was mistaken."
The manager turned to Josie.
"May I ask who you are, Miss, and how you came to be in my office?"
"I am Josie O'Gorman, an agent of the government secret service," she replied, not quite truthfully. "I've been shadowing this man for some time. I tell you, sir, he brought a bomb here, to destroy this building, and under pretense of lighting, a cigarette he has just lighted the time fuse. The bomb was in that satchel, but—" she added impressively, "as a matter of fact the thing was harmless, as I had already removed the powder from the fuse."
Kauffman gave a low whistle.
"How did you manage that?" he asked curiously.
"Never mind how," she retorted; "I did it."
