"Even if I couldn't get the paper, I could prove that he had not gone west, as he told his aunt, and I could follow him, and find out where he was stopping."
"Well, you can do the watching if you wish. I will give you Andrew V. Shanley's address. His place of business is between here and the Bridge."
"Shall I go there at once?"
"If you wish."
The address was written on a slip of paper, and a little later Nat and his employer separated. John Garwell gazed after our hero curiously.
"He is improving wonderfully," he mused. "He isn't half as green as when I first met him."
Nat had been told what car to take, and ten minutes sufficed to bring him to the block upon which Andrew Shanley's office was located, on the third floor of a large office building. He went upstairs, and managed to get a peep into the office, and found Rufus Cameron was not there.
"Of course he may have been here already," he told himself. "But I've got to take my chances about that. I'll stay here until the place shuts up."
Going below again, he took a station across the street and began to wait patiently for the appearance of Rufus Cameron.
