In the fourteen exciting days and nights which followed, I motored many hundreds of miles over Surrey, Sussex, and Kent, instituting inquiries and making a number of amazing discoveries, not the least astounding of which was that, only one hour prior to the reception of that message on the first evening of our vigil--"H. 5"--five German aeroplanes had actually set out from the Belgian coast towards England! That secret information was being sent from the Kent coast to London was now proved, not only at one point, but at several, where I have since waited and watched, and, showing signals in the same code, have been at once answered and repeated. And every night, until the hour of writing, this same signalling from the coast to London is in progress, and has been watched by responsible officers of His Majesty's Service. After the first nights of vigilance, I had satisfied myself that messages in code were being sent, so I reported--as a matter of urgency--to the Intelligence Department of the War Office--that department of which Mr. McKenna, on March 3rd, declared, "There is no more efficient department of the State." The result was only what the public might expect. Though this exposure was vouched for by experts in signalling, men wearing His Majesty's uniform, all the notice taken of it has been _War Office, Whitehall, S.W._ 27th February 1915. _The Director of Military Operations presents his compliments to_ Mr. W. Le Queux, _and begs to acknowledge, with thanks, the receipt of his letter of the_ 25th inst. _which is receiving attention_. a mere _printed acknowledgment_--reproduced above--that my report had been received, while to my repeated appeals that proper inquiry be made I have not even received a reply! But further. While engaged in watching in another part of Surrey on the night of March 3rd, certain officers of the Armoured Car Squadron, who were keeping vigil upon the house of mystery, saw some green and white rockets being discharged from the top of the hill. Their suspicions aroused, they searched and presently found, not far from the house in question, a powerful motor-car of German make containing three men. The latter when challenged gave no satisfactory account of themselves, therefore the officers held up the car while one of them telephoned to the Admiralty for instructions. The reply received was "that they had no right to detain the car!" But, even in face of this official policy of do-nothing, they took off the car's powerful searchlight, which was on a swivel, and sent it to the Admiralty for identification.
