It was about a week later that Nick Carter received a note from the president of the railroad which caused him great astonishment. It was brief and to the point. It read:

"Can you call on me at once? Black Madge has escaped."

That was all, but it was enough to stir the detective to action, and, taking Patsy, who happened to be in when the message arrived, along with him, Nick at once visited the office of the railroad.

"Well, Carter, it didn't take long for Black Madge to make good her threat, did it?" said the president as he rose and shook hands with the detectives.

"I think," replied the detective, smiling, "that, considering the trouble we were put to in capturing her, it was a very short time for us to hold her. Now, what can I do for you, Mr. Cobalt?"

"Do? Why, you can catch Black Madge again for us."

"Oh," said the detective, smiling. "Can I? Well, possibly."

"You see," the president continued, "we have called a hasty meeting of the board since the information of the escape of Black Madge came to us, and we have decided that no effort shall be spared to get that woman into custody again. At liberty, she is a constant menace to the welfare of the road, and of every town along the line, as well as of everybody who lives in those towns."

"I'll admit that she's a bad one," said Nick.

"We don't want her at liberty. With the following she has, she is a dangerous woman—much more dangerous than a man would be in her position."
