“Evelyn Grimm!”
 
Old King Brady repeated the name with a horrified gasp. Both detectives rubbed their eyes.
 
“Did I hear you aright?” asked the old detective. “Did you say the name was Grimm?”
 
“Yes, sir.”
 
The young girl looked at him wonderingly.
 
“You lived in Westchester?”
 
“That is my home.”
 
“Do you know Napoleon Blood?”
 
The young girl shuddered.
 
“He is my uncle,” she said. “He it was who declared I was insane and had me brought here!”
 
Old King Brady began to see his way through the fog.
 
The vile plot in all its intricacies was now exposed to him.
 
“That was the way of it,” he said. “Then you did not keep an appointment in union Square on a certain evening?”
 
“Never!”
 
“Nor you were not murdered and burned up in a Fifteenth street house?”
 
The young girl looked astonished.
 
“I do not understand you,” she said.
 
“I do not wonder,” said the old detective. “I will explain. That is the story of your mysterious disappearance as given to the world by your uncle.”
 
“Well, it is false!”
 
“Even traces of your clothing were found and other clews to show that you were burned in that dwelling.”
 
“That is strange.”
 
“Yes, it is part of the plot.”
 
“Plot?”
 
“Yes, young lady, you are the victim of a villainous plot.”
 
“I think you are right,” said Evelyn, with conviction. “And I believe my uncle is at the bottom of it. I know he always hated me and he wanted my heritage.”
 
“Now you have it right,” said Old King Brady. “He tried to hang young Allerton Banks for the supposed crime, but an alibi was proved.”
 
A cry of horror and indignation escaped the young girl.
 
“The scoundrel!” she said, intensely. “He always hated Allerton. Oh, sir, who are you? Surely you do not keep this dreadful place?”
 
“Sh!” said Old King Brady, in a whisper. “We must be careful. No, my dear young lady, we do not. We are New York detectives, of the Secret Service. We are in quest of the villains who were supposed to be your murderers!”
 
Evelyn Grimm was plainly surprised and delighted.
 
“Oh, heaven be praised!” she said, ardently. “You will save me. You will take me back to New York. In another year my heritage will be mine. I shall contest my uncle’s right to put me in an insane asylum.”

“And well you may. It is as you say, only a scheme to beat you out of your inheritance.”
 
“Uncle Napoleon will pay for it.”
 
“We promise you he will. But now let us consider what is to be done. Very naturally you are anxious to escape.”
 
“Yes.”
 
“But there are many things to consider. In the first place there is a terrible risk!”
 
“Indeed!”
 
“You see the gang of villains with whom your uncle is in league are here to-night. We want to entrap them.”
 
“Then I must wait?”
 
“Perhaps so. Or—it might be as well for us to liberate you now. But you must be very careful and not betray us.”
 
“Oh, I will promise.”
 
“Very well.”
 
The detectives now lifted the iron bar and opened the cell door.
 
It creaked a bit, but after listening carefully the detectives were convinced that they were not betrayed.
 
In another moment Evelyn Grimm, the supposed victim of the Fifteenth street crime, walked out safe and well.
 
The Bradys felt that they had made a great step toward the winning of this remarkable case.
 
While they knew that the crime charged against the trio was thus disproved, yet there was sufficient evidence against the gang to hold them for the law.
 
So they did not deem the case by any means ended, with the liberation of Evelyn Grimm.
 
Along the corridor to the end of the wing they now all crept.
 
It had been decided by the Bradys what was to be done.
 
At the end of the wing there was an iron fire-escape.
 
It would be easy to descend by this to the ground.
 
Luckily Evelyn knew the use of snowshoes. Harry was to accompany her to the Paine farm house.
 
Then he was to organize a band of the farmers, armed, and return. The asylum would be surrounded.
 
It seemed that this must be a certain way of capturing the gang.
 
“Queer, isn’t it?” said Harry. “The charred remains of a body were found in the ruins of that Fifteenth street fire.”
 
“Very good.”
 
“Well, now we find Evelyn Grimm alive.”
 
“Yes.”
 
“But I cannot see that that disproves the crime of murder. A murder must have been enacted.”
 
“Beyond a doubt.”
