"No, my friend, we acknowledge nothing of the kind. Be good enough to attend to your own business."

"It is time that I did," replied the inventor; "I have neglected it long enough."

Stephen Trimble walked out of the building. He had three things to do—to discover the landlord of Rickett's Court; to see his wife for the last time; and to free his little son, whom he believed to be still in prison.

There was quite a commotion in the court; some men were putting up a fire-escape. "What ever put it into Solomon Meyer's head to do that?" he asked.

"'Tain't Solomon Meyer," a workman replied; "it's the landlord himself. He ordered it done some time ago, and was mad as a hornet because Meyer hadn't attended to it."

"See here, my friend," said Stephen Trimble, "if you know who the landlord of this tenement is, you will do me a favor by directing me to him."

"Armstrong's the man—Alexander Armstrong, President of the —— R. R. Co.; his office is over the banking-house of Roseveldt & Gold, No. —— Broadway. He rooms there too, when he's in town—back of his office."

Stephen Trimble stood very still for a moment. The information which he thought would be so difficult to obtain had come to his door. The vengeance which he had fancied might take long days and nights of plotting, hung now over the man who had wronged him. He need do absolutely nothing, and Alexander Armstrong was doomed. He must inevitably be killed in the explosion and conflagration which was planned to cover the robbery of the bank beneath him.

They had changed places, and the landlord of Rickett's Court was his victim. One-third of his task was accomplished. He walked now in the direction of the hospital, and asked to see his wife. He hardly expected to be admitted, but he would at least make the attempt. To his surprise he was shown into a cheerful parlor, and Mrs. Trimble was sent for. She came down, looking pale, but happy.

"O Stephen," she cried, "it has been so long since I have seen you! but never mind, I am almost well now, and we shall soon be together again. The doctor tells me I may leave next week. They have been so very kind to me here, it has been like Heaven. The rich are thoughtful and generous to provide such places for the poor. I am so grateful; and I have rested so that I shall be able to take hold with new courage."
