The case of the barber Ernst was a good instance. This man had carried on business at the same shop _for sixteen years_, and we can be quite sure that the last thing his neighbours thought of him was that he was a spy in German pay! No. He was a good Englishman like the rest of us. Yet, it was shown that he was a secret agent of the most dangerous character, and even worthy of a personal visit from the great and distinguished Steinhauer himself! Now I hope that the many who have read my books over the last twenty years will at least believe that I am one of the last men to be suspected of any desire to belittle my own countrymen. I am simply an Englishman who has tried to interest them. To-day I point a peril to each and all of my million readers. But I wish to make it quite clear that nothing I say in this connection should be taken as reflecting on the work of our Confidential Department--a department which has done magnificently and which in every way I respect. They have matched brains against brains, and cunning against cunning, and the balance of the account is decidedly in their favour. They have, indeed, fooled Steinhauer's agents all through--examined their correspondence and their reports, tracked the agents down by the information thus gained, arrested a large number of them, and to a very great extent smashed the organisation in its original form. So much I cheerfully admit, and congratulate them heartily upon their success. My point is that the work has not gone far enough, that what they have done has not been adequately supplemented, that much yet remains to be done before we can assume that a reasonable degree of security has been attained. On October 8th last, a very important statement was issued by the Home Secretary, describing the steps that had been taken "to deal with the system of espionage on which Germany has placed so much reliance." I have shown elsewhere how the Confidential Department came into being, and how it was able to "discover the ramifications of the German Secret Service in England." In this statement Mr. McKenna says:-- The agents ... were watched and shadowed without in general taking any hostile action or allowing them to know that their movements were watched. When, however, any actual step was taken to convey documents or plans of importance from this country to Germany, the spy was arrested, and in such cases evidence sufficient to secure his conviction was usually found in his possession.
