It is often said that the Germans do not require to pursue any system of espionage in England when they can purchase our Ordnance maps at a shilling each. But do these Ordnance maps show the number of horses and carts in a district, the stores of food and forage, the best way in which to destroy bridges, the lines of telegraph and telephone, and the places with which they communicate, and such-like matters of vital importance to the invader? Facts such as these, and many others, are being daily conveyed by spies in their carefully prepared reports to Berlin, as well as the secrets of every detail of our armament, our defences, and our newest inventions. During the last twelve months, aided by a well-known detective officer, I have made personal inquiry into the presence and work of these spies, an inquiry which has entailed a great amount of travelling, much watchfulness, and often considerable discomfort, for I have felt that, in the circumstances, some system of contra-espionage should be established, as has been done in France. I have refrained from giving actual names and dates, for obvious reasons, and have therefore been compelled, even at risk of being again denounced as a scaremonger, to present the facts in the form of fiction--fiction which, I trust, will point its own patriotic moral. Colonel Mark Lockwood, Member for Epping, sounded a very serious warning note in the middle of 1908 when he asked questions of the Minister for War, and afterwards of the Prime Minister, respecting the presence of German spies in Norfolk, Suffolk, Essex, and elsewhere. He pointed out that for the past two years these individuals, working upon a carefully prepared plan, had been sketching, photographing, and carefully making notes throughout the whole of East Anglia. With truth, he declared that this organised system of espionage was for one reason alone, namely in preparation for a sudden raid upon our shores, for "the Day"--as it is known in Germany--the Day of the Invasion of England. The replies given by His Majesty's Ministers were colourless, though they both actually confessed themselves unable to deal with the situation! Under our existing law it seems that a foreign spy is free to go hither and thither, and plot the downfall of England, while we, ostrich-like, bury our head in the sand at the sign of approaching danger.
