One of the most useful pieces of information picked up was a list of names and addresses of persons to whom letters from Germany were sent for distribution, and who were spies at Chatham, Sheerness, Portsmouth, Rosyth, and other places. An amusing feature of the case was that after all these letters had been carefully examined and copied by the Post Office they were delivered in the ordinary course with only a very slight delay, and thus the suspicions of the spies, if indeed they entertained any, were most effectually put to sleep. The Nameless Department was not quite the fool the Germans had some excuse for thinking it! An important discovery made early in the case was the _nom de guerre_ of Steinhauer of Potsdam. He had at that time become "Mrs. Reimers." "Mr. J. Walters, c/o K.G. Ernst" was soon found to be Ernst himself, who had long before suggested the adoption of that name to avoid suspicion. It will illustrate the thoroughness of German methods to mention that most of the letters sent to Ernst were written on English paper, so that when he posted them there would be nothing to call special attention to them. One of the letters from Steinhauer read in court was a request for English paper and envelopes, which Ernst duly forwarded as "samples." Many of the letters intercepted by the Post Office contained money, mostly in the shape of bank-notes. The work that Ernst was doing was sufficiently important to justify a visit from the redoubtable Steinhauer himself, as we learn from Ernst's own statement. During the time he was in custody Ernst made a statement to a detective in which he said:-- I am sorry I was introduced into this business. Kronauer introduced me. I thought it was only a private inquiry business. I have only seen Steinhauer once. That was just before Christmas in 1911. He came to my shop on a Sunday morning. My shop was open and I had several customers there. He said to me, "Are you Mr. Ernst?" and I said, "Yes." He said, "Do you know me?" I said, "No." He said, "You have heard of me, I am Steinhauer. I see you are busy now. I want to have a quiet chat with you. I will come back after the shop is closed. What time do you close?" I said, "Twelve o'clock." He said, "All right, I will come back after that, and went away. He returned later and came into my parlour, where we sat down and had a long talk." This statement is exceedingly interesting, as we know that Steinhauer, as described in another chapter, was in London about this time, when he actually went to Buckingham Palace as a member of the Kaiser's suite. That he should be able to spare time to visit a man in Ernst's position shows what work the latter was doing, and also throws a good deal of light on the class of agent most useful to the Germans--the "small" man, whose insignificant position does so much to guard him against suspicion.
