“Very well. Go on.”

“The ambassador whom I represent was directed to carry on the secret work of that affair, and to direct it from his embassy, in Washington. He has done so. In carrying on the work a mass of documents has collected. They are entirely apart from his regular official duties as ambassador to the United States.”

“I already understand that, sir.”

“Among those documents which have collected, there are certain papers which, if placed upon this table in one package, might be contained in a rubber band, and might be deposited within the space contained in your greatcoat pocket. As I have stated, those documents—those to which I am referring just now—are of vast importance.”

“I think I am sufficiently well assured of that, colonel.”

“As a means of safety, these papers were not only written in cipher, but they were then redrawn, in halves, and the originals were destroyed. They were drawn up and written in such a manner that neither half of them could be deciphered without the other half. Do you follow me?”

“Perfectly.”

“Those two halves, each necessary to the other half, were concealed, hidden away for safe-keeping, by the ambassador in person, in places known only to himself supposedly; in localities widely different. Understand that they were not yet complete, or they would have been forwarded to St. Petersburg before now. That is what was to be done with them as soon as they were completed.”

“Yes.”

“They would, each half by itself, have been sent to St. Petersburg—and by entirely different routes. For example, I might have been dispatched there with one-half of them in my charge, ignorant of what I carried with me, save only that they were documents of importance to be delivered exactly as directed.”
