Spies of the Kaiser: Plotting the Downfall of England. Le Queux William

make any statement, though he could speak English well and write it perfectly, as shown by the note on his plan of the new boat; therefore we landed him at the Stony Steps across at Gosport. Before we left him we gave him to understand that if he did not at once leave the country he would be arrested. Yet so absurd is our law that I doubt whether we could have given him in charge even though we had wished!

      We rowed back across to the landing-stage at Portsmouth Harbour Station, and after we had seen Vera safely home we returned together to the "Queen's" at Southsea, where, in the secrecy of Ray's bedroom, we examined the spy's plan of the new submarine, and read his memoranda, which were in German, but which translated were as follows:

      "Report by Leon Karff, late foreman-fitter at Kiel Dockyard, on Submarine 'F 2,' now building in Shed No. 4, Portsmouth Dockyard.

      "This boat would appear to me to be of about 700 tons displacement when complete, possibly rather over. She is, as far as I am able to measure, about 180 feet long with an extreme beam a little forward of amidships of 20 feet. She is fitted with three propeller shafts with three small four-bladed propellers on each. As she is provided with what appear to me to be some kind of turbine engines, I imagine that the centre shaft is for going astern only. The propellers on this shaft seem to be attached in such a way that they could be 'feathered' by suitable gearing on board so as not to retard the vessel's way when going ahead. The engines of this boat are of a type which I have never before seen. I imagine that they are a combination of the new 'gas-producer' engine and the turbine system, the explosion of the combined gas and air being split up and passing into the turbine through a number of different channels simultaneously. This would be a very economical system if the necessary power can be obtained, and would be much safer for use below than petrol engines.

      "The boat is evidently intended to operate a good deal in an 'awash' position, for there is fairly thick armour-plating over the greater part of the upper side of the bow, while the fore end of the superstructure is made of two 6-inch Krupp steel plates meeting at an acute angle, and so forming a kind of stem when the boat is moving in this way. The space enclosed between these two plates is evidently intended to be used as the conning-tower. Here there are a periscope, steering-wheel, voice-tubes, and everything necessary for the control of the vessel. There are two horizontal propellers or fans, which seem to be driven by electricity derived from an installation of accumulators, and which are certainly intended to secure horizontal immersion, so the vessel will not plunge or dive, but immerse herself horizontally by means of these propellers, which, by the way, work in vertical shafts running completely through the boat, one forward and the other aft, as was the case in the Nordenfeldt, Waddington, and other early submarines.

      "Forward there is an air-lock and diving-chamber, as in the 'Lake' boats, so that divers can get in and out of the vessel whilst under water. It would also afford a means of escape for the crew in the case of accident. This is further provided for by a detachable boat or caisson at the after end of the superstructure capable of holding ten men, I should say, or possibly a dozen. There are also appliances which I suppose are telephone buoys for communicating with the surface. There are six torpedo tubes fitted, one forward, one aft, and the others two on either broadside. And there seems to be provision for six other torpedoes of the 18-inch type.

      "There is a long rudder for ordinary steering, and four horizontal ones or planes which are placed abreast the horizontal screws and which, I imagine, act automatically in conjunction with them, as they seem to gear up with the shafts for these propellers. There is a big safety detachable weight which fits loosely into a recess amidships, and four broad wheels with ball bearings which do not fold up as in the 'Lake' boats, but always protrude nearly half their diameter. After all they would not obstruct her way when water-borne more than a keel – or very little more. They are quite independent and unconnected with the interior of the vessel, which while resting on them would receive forward impetus from her propellers. In the 'awash' position she would offer a very small and almost invulnerable target."

      "Well," I said, marvelling at what we had translated. "What induced you to believe that the cryptogram had any reference to the new submarine."

      "Those figures '6.11' puzzled me greatly," he replied; "but at last I deciphered them as 'F. 2' – F being the sixth letter of the alphabet – the number of our newest and most formidable submarine, which was being kept such a strict secret by the Admiralty. 'Royal Pier' is the name of the hotel in which Steinheim stayed at Southsea, and 18 the number of his room. From facts I elucidated, it was made plain that Max Steinheim was about to embark upon the investigation, being in secret communication with Hartmann, and was to meet Karff at Charing Cross Station. This Steinheim had already, by an ingenious device, secured from a private of engineers named James Ward – whom I have seen – certain information regarding the new boom defences of Portsmouth Harbour. Ward, whose home is at Great Weldon, suddenly discovered to his horror that the man was a German spy, followed him to Guildford, attacked him in the train, and left him for dead. For that reason Steinheim has refused to make any statement to the police. When I saw Ward a week ago, he explained how innocently he had fallen into the trap which the cunning Steinheim had laid for him."

      "The evidence you have here in black and white will surely prove convincing," I remarked. "You will go and see Steinheim again, I suppose? He is still in the hospital."

      "No. We shall remain silent. To show our hand will only place Hartmann on the alert. To do that is needless. We have prevented the plan of our new submarine going to Germany, and for the present that is sufficient."

      And my friend drew up the blind and gazed out upon the rosy dawn across the water.

      CHAPTER III

      THE BACK-DOOR OF ENGLAND

      "Well, that's rather curious," I remarked, closing the door of the old oak-panelled smoking-room at Metfield Park, and returning to where my friend Ray Raymond was seated.

      "Was anyone outside the door?" he asked, quickly on the alert.

      "Mrs. Hill-Mason's German maid. You remember, Vera pointed her out yesterday."

      "H'm! and she was listening – after every one else has gone to bed!" he remarked. "Yes, Jack, it's curious."

      It was past one o'clock in the morning. Two months had passed since the affair down at Portsmouth, but we had not been inactive. We were sitting before the great open fireplace where the logs were blazing, after the rest of the men had taken their candles and retired, and had been exchanging confidences in ignorance of the fact that the door remained ajar. I had, however, detected the frou-frou of a woman's skirt, and creeping across to the door had seen the maid of one of the guests disappearing down the stone passage which led to the great hall now in darkness.

      Metfield Park, three miles from Melton Constable, in Norfolk, the seat of the Jocelyns, was a fine old Tudor place in the centre of a splendid park, where the pheasant shooting was always excellent. Harry Jocelyn, the heir, had been with us at Balliol, hence Ray and I usually received invitations to the shooting parties. On this occasion, however, Vera Vallance with her aunt, Mrs. Mortimer, had been invited, much to Ray's satisfaction.

      Among the party was a well-known naval officer, captain of a first-class cruiser, two military officers, and several smart women, for both Sir Herbert and Lady Jocelyn moved in a very smart set. Several of the ladies had joined us in the smoking-room for cigarettes, and the conversation around the fire had been mainly the usual society chatter, until at one o'clock every one had left for bed except our two selves.

      Over the great fireplace were the arms of the Jocelyns carved in stone, with the date 1573, and in the corner near the window was a stand of armour upon which the dancing flames glinted ever and anon. Through the long uncurtained window shone the bright moon from over the park, and just as I reseated myself the stable clock chimed the half-hour.

      We had been there four days, and the sport had been excellent. On the previous day Ray had excused himself on account of the bad weather, and had spent the hours mostly with Vera.

      It was of how he had employed his time that he had been telling me when I had discovered the eavesdropper.

      "I wonder why our conversation should prove so interesting to that maid?" he remarked thoughtfully, gazing into the fire. "She's rather
