Germans have been found in possession of hotels and mansions in strategic positions all over the United Kingdom, and to-day numbers of alien enemies--thanks to the order which has released them from the internment-camps--are actually employed at the various great railway termini in the Metropolis! Fancy such a state of affairs being permitted by Imperial Germany--a country in which British prisoners of war are half-starved, as evidenced by a cleverly composed letter before me from one who is unfortunately a prisoner, and which passed the German censor, whose knowledge of English was not so extensive as to cause him to suspect. When the reader has digested the pages which follow--chapters which give a very lucid, calm, and first-hand idea of the low-down methods of German espionage, he will, I venture to think, agree that it is of no use to cross the barbarian's sword with a peacock's feather. Germany intends, if she can, to crush and to humiliate us, to devastate our homes, to outrage and massacre our dear ones, and by every subtle and dastardly means, to bring upon us a disaster so stupendous as to stagger humanity. Shall we remain lulled to sleep further by assurances which are not borne out by facts? Germany's advance guard of spies are already here, rubbing shoulders with us, many of them smug and respectable citizens passing among us entirely unsuspected, members of our churches, honoured, and believed to be Britons. Some are alien enemies, others are traitors, who have imperilled this country's safety for the lure of German gold. In another place I have fully explained how the German Government held out an alluring bait to myself. If this was done to me, then surely it has been done to others. We are Britons, fighting for our King and our Country. Our fathers, husbands, sons, and brothers, have gone forth to battle for the right and hurl back the barbaric Teuton-tide which threatens to overwhelm us. Some, alas! already lie in their graves. Is it therefore not our duty to those we hold dear to see that spies shall not exist in our midst? If the Government are so utterly incapable of dealing effectively with the problem, as they are now proved to be, then why do they not allow the formation of a Central Board, with drastic powers, to end at once this national danger, which grows more acute with the dawn of every day?
