The offices of Rosencrantz and Guildenstern were to be used as a kind of Secret Service Bureau. Whether or not England joined in the conflict, the United States would, in any case, remain neutral. From New York, intelligence could be transmitted direct to Berlin, and vice versa. Von Essling's agents--one of whom was to be Rudolf Stork--acting as spies in the war area, would transmit, or bring personally, the information they gathered to Rosencrantz, who would represent the Baron, who would sift all intelligence, and supervise cyphered telegrams to the Intelligence Department in the Wilhelmstrasse in Berlin. For the present absolute secrecy was to be maintained.

Von Essling ended. There was a brief pause, during which Stork spat upon the floor.

"And may I ask," said he at length, "what guarantee I am to have? I don't, mind you, say that all this is not true; but, still, business is business, and no man takes on board a cargo without a manifest, which is a kind of passport on the sea."

"You are quite right," said the Baron. "I can supply you with credentials which will instantly dispel such doubts. I have already entrusted to Mr. Rosencrantz papers of the utmost value, which will prove to you that we are perfectly sincere, that it will be worth your while to help us."

It was then that Rosencrantz got to his feet, and shuffled about the room.

"It so happens," he observed, "that the papers you mention are in a certain leather box which was given into the charge of my secretary."

Von Essling gave vent to an exclamation of surprise.

"You take grave risks!" said he.

"My dear Baron," replied the other, "the girl can be trusted implicitly. And besides, she is totally ignorant of what the box contains."

Von Essling had something else to say, but Stork took him up.
