As luck would have it, he had waited less than half an hour when he saw Mrs. Parloe's nephew step from a car at the corner, and approach the office building.
"Mr. Cameron, I want to see you!" he exclaimed, coming forward, and confronting the man.
Rufus Cameron had not expected to meet Nat again so soon, and for the moment he was dumfounded.
"Wha—what do you want?" he stammered, halting.
"You know well enough what I want," answered our hero, sharply. "I want that document you stole from me."
"Stole from you!"
"That is what I said, Rufus Cameron."
"I—I don't know what you are talking about."
"You do know, and unless you give up the paper I am going to have you arrested right now."
At these words Rufus Cameron turned pale. As said before, he was a good deal of a coward, and being caught so unexpectedly threw him somewhat from his mental balance.
