"Brother Gregory,--I send you this hastily and with some apprehension. Both Nicholas and Dmitri (the Grand Dukes), are actively at work against us! Beware! They know far too much, hence it behoves us to be most discreet. I was at Tsarskoe-Selo yesterday and discussed it with F. (Count Fredericks, Minister of the Imperial Court). There is a secret movement to upset our plans, but I have ordered the Secret Police to spare no pains to present full and adequate reports to me, and rely on me to take drastic steps. "An hour ago it came to my knowledge that an individual named Wilhelm Gebhardt, living at Hildegard-strasse, 21 Wilmersdorf, Berlin, has knowledge that you are in the German capital and is probably watching your movements to report to our enemies here. Give news of this to our friend `Number 70' and urge that he shall be immediately arrested as a spy of Russia. If he is executed his mouth would be closed, for he is dangerous. The man with whom he is in association in Petrograd, a person named Tchartovyski, member of the Duma, I have ordered to be arrested and charged with communicating with persons in Germany. "S. (Sturmer) is eager for news regarding the proposed German offensive against the British in Flanders, and the exact position regarding the `U' boat campaign. Inform the Chancellor that news we received from Washington to-day shows that President Wilson is determined, and warn him that J. and G., whom he will know by initials as German agents in the United States, have been discovered, and may be arrested. He may perhaps communicate with them by wireless, and they may escape while there is still time. "Further, inform the Chancellor that our efforts to make more marked the shortage of food have been negatived by the action of Nicholas and Dmitri, for we fear to go further lest the truth be disclosed. Their activity cannot be ignored. "Urge that the distribution of fruit to charitable institutions be repeated. "The charges against Sukhomlinoff are extremely grave, and may have serious consequences. I am, however, taking steps to ascertain the intentions and to arrest those who are in association. "Her Majesty is eager and nervous regarding you. Write and assure her that all is well with your dear self. As the saviour of Russia from the wiles of the Allies, the Russian people ought to regard you as great as the Great Peter himself. "A tall, thin individual named Emil Dollen will probably call upon you at your hotel. If so, receive him. He may convey a message from me sent by wireless to Riga and re-transmitted. "Present my humble compliments to His Majesty the Emperor. Would that I were with you at glorious Potsdam. These Russians of ours are arrant fools, or we should have been hand-in-glove with Berlin against the effete nations who are our Allies. I salute you and await your return.--Your brother, D.A. Protopopoff."
