A cold smile played about Bivens's mouth for a moment.
"You don't suppose I would make a statement like that unless I know it to be true?"
"I found all your other facts correct. This I haven't been able to verify. You make it incidentally, as though it were a matter of slight importance. To my mind it's the key to the man's character and to every act of his life. How did you discover it?"
"Very simply."
Bivens walked to his door, opened it, looked outside, stepped to one of the great steel safes and drew its massive doors apart. He pulled a slip from a cabinet fitted with a card-case index, noted the number, replaced the card, opened another door and drew out a manuscript notebook of some three hundred pages of type-written matter. Each page was written without spacing and contained as many words as the average page of a printed novel. On the back of the morocco cover was printed in plain gold lettering:
"THE PRIVATE LIFE OF NO. 560."
He handed the volume to Stuart, closed the safe, and resumed his seat.
"You may take that book with you, Jim," he said quietly. "I trust to your honour not to reveal its contents except in the discharge of your sworn duty as an officer of the law. You will find in it the record of the distinguished president's private life for the past ten years without the omission of a single event of any importance."
Stuart glanced through the book with amazement.
"How did you come into possession of such facts?"
