That night the woman Stolberg returned at five minutes to eleven, and later, when Ray went upstairs with me, I described what I had seen.
Next night, instead of following her out, I waited at the spot at half-past ten, when, sure enough, the car returned ten minutes later and deposited her. The number plates, however, were obliterated by the mud both front and back purposely it seemed to me. The man within shook her hand as she alighted, but I could not see his face. Was he some secret lover? Apparently she went no great distance each evening, going and coming from the direction of Holt.
On the following day I took several opportunities of watching the woman at close quarters. Her eyes were peculiarly set, very close together, her lips were thin, and her cheek-bones rather high. Otherwise she was not bad-looking. Mrs. Hill-Mason had, of course, no idea of her maid's nocturnal motor-rides.
Whether the woman had any suspicion that she was being watched I know not; but on the next night when Ray took a turn at keeping an eye upon her, she did not go out, but on the next she went, and Ray followed her to the park wall, but saw nothing more than I had done.
All this time, of course, Vera was greatly interested in the result of our observations. Through her own maid, Batson, she discovered the room occupied by the German, and to this I made my way, at considerable risk, one morning while the maid was busy attending upon her mistress. I had a good look through her belongings, finding in her trunk a small, flat tin box, japanned dark green, strong, and secured by a lock of well-known make. What, I wondered, did it contain?
Could I have but seen the number of the mysterious car I could have discovered the identity of her nocturnal visitor.
The same day that I discovered the tin box in her trunk, Mrs. Hill-Mason, however, returned to London, taking with her the mysterious Fräulein.
Three days more went by, and I was about to dismiss the affair as a combination of curious circumstances. Vera and her aunt had left to pay a visit in Worcestershire, and Ray I were due to go up to town that morning, when he entered my room, saying abruptly:
"I'm not going to London yet, Jack. I shall go over to Cromer instead."
"Cromer!" I echoed. "Hardly the time of year for the seaside."
That same grey chilly afternoon, in the grey falling light, we sat upon one of the seats of the pier at Cromer gazing seaward, towards where the German coast lay beyond the indistinct horizon. The place was deserted save for ourselves. On the cliff behind us stood the long red façade and many gables of the Hotel de Paris, where we had put up, while in the background rose the square old church tower, the landmark of mariners from Haisborough Gat to the Dowsing.
"There's just a chance of us falling upon something interesting about here," Ray was saying, as he pressed the tobacco into his pipe, and by the expression upon his keen clean-shaven face I saw that he had scented the presence of spies. "Has it never struck you," he went on, "that the east coast, where we now are is the most vulnerable spot in England, and the first objective of the Kaiser's army? Every soldier and sailor in Germany dreams of 'the Day' the day when he will set foot upon this shore. For some years past our Intelligence Department has known of the German plans for our invasion. There are several, but in each one a dash, and a surprise landing along this coast of Norfolk and of Suffolk and Essex is the first step. Knowledge of this prompted Lord Roberts to resign his seat on the National Defence Committee and make those stirring speeches pointing out our country's peril."
"And what thanks did the country give him?" I interrupted. "People only laugh at him for his trouble!"
"Yes," said my friend bitterly, "the public are ignorant, therefore they do not heed. They talk glibly about the strength of our navy, forgetful that the German diplomacy is the cleverest and most cunning in the world. When 'the Day' dawns there will be no suspicion of war, and certainly no declaration of hostilities. Before we have realised that war is in the air, the enemy will have their feet firmly planted upon British soil."
"And if the enemy intend landing along this shore, it is certain that spies are active here, gathering all information likely to be of service to the invader."
"That's exactly why I've come here, my dear Jack," my friend said. "We know that our eastern counties have been divided into districts by the Germans, and in each one or more secret agents are busily at work taking notes of food supplies, forage, blacksmiths' shops, motor-cars for transport, the destruction of telegraphs and telephones, positions for artillery, and the best mode of advance south to London. One may rest assured that the ordnance map is being very much amplified just now."
That evening we spent idly in the hotel, and next day, hiring a motor-car, we drove through Runton to Sheringham and over the hills three miles further towards the back-door of England the place neglected by those responsible for our defences, and by the public alike Weybourne.
The road from Sheringham ran down a steep hill, called the Fox Hill, to the little village that lay cosily at some distance from the sea. Passing the church we turned sharply to the right, and in a few minutes found ourselves against a large front with a wide open beach beyond.
Having alighted, we walked along beside the surf for some distance, out of hearing of our chauffeur, when my friend exclaimed:
"Here is one of the spots which the Germans have chosen for landing. Look at it! Everything is in favour of a hostile force. That range of hills we've just come over at the back would be occupied by the landing force at once, and thus they would command the whole country from Kelling, which you see to the right, away south beyond Cromer, down to Baxton beyond Mundesley."
With my back to the long rolling breakers I gazed away landward at the long line of hills stretching in each direction. It was, indeed, an ideal spot for an enemy to effect a landing, with deep water right up to the land.
"Because of the confidence we have in our fleet and our wonderful diplomacy this place is no longer watched," Raymond remarked, standing beside me muffled in his motor-coat, for the wind was intensely cold. "Yet in days gone by, by reason of the facilities which nature has provided for the landing of hostile forces, it was carefully guarded whenever the invasion of England was believed to be imminent."
After we had strolled some distance along the beach, where the grey-green waters were breaking into foam, my friend suddenly halted and, taking a piece of paper from his pocket, stood with his back to the sea and made a sketch of the irregular contour of the blue hills facing him from the coastguard at Salthouse on the right to the rising ground behind Upper Sheringham on the left the positions which are to be first occupied by the enemy in their attack upon us.
He made no explanation of the reason of his action, therefore I stood by watching in silence.
At last we returned to the car and drove inland to Weybourne village, a sleepy old-world little place from which the sea has receded. As we turned into the main road he ordered the man to pull up, and, descending, looked about him, first at the lines of telegraph-wire running beside the road, and then we both strolled through the village. My companion's eyes were everywhere. He appeared to be making mental notes of every feature of the obscure little place.
Just as we were returning to the car he suddenly halted, saying:
"You go on. A thought has just occurred to me." And, turning, he walked back to the small village post office situated next door to an inn, and was absent for nearly a quarter of an hour.
"As I suspected!" he remarked beneath his breath as he rejoined me. "That inn is kept by a German!"
Then we travelled along to Cley-next-the-Sea, and thence by way of Candlestick Hill and through the wooded country around Holt, back to Sheringham, where we lunched at the "Burlington."
His manner had changed. He had again become serious and thoughtful. A cycling map of the district which he had bought in Cromer that morning he brought out, and as we sat together in the smoking-room he spread it upon the table and began measuring distances with a slip of folded paper.
The car was at the door at four o'clock, and we were in the act of moving off, when by mere chance I looked up at the second floor of the hotel. What I saw caused me to hold my breath.
A face was at one of the windows watching us.
I nudged my friend, and cried, "Look!"
But when he raised his head it had gone. Indeed, the white face had only showed there for a single instant, yet it was a countenance that I too well remembered, it was unmistakable that of Fräulein Stolberg!
I told Ray as we whirled along into the town. But he only grunted in surprise, and remarked that we were going to Beccles.
Why was that woman there instead of being with her mistress, who, we had ascertained, was now visiting at Cheltenham?
Our way lay first back to Cromer, where we joined the direct Norwich road by way of Aylsham, but about four miles after passing Cromer the road divided. The left-hand one ran to our destination, but at Ray's orders we took the right-hand one, and in the darkening twilight struck across a wide heath, which I afterwards learnt was called Roughton Heath, until we passed an old windmill, and entered the small crooked village of Roughton. We passed beyond the place for a quarter of a mile, and then descending, walked forward until we came to a good-sized, comfortable, old-fashioned house, probably of the days of Queen Anne, that lay behind a high red-brick wall.
Through the iron gates I noticed, as we paused, a wide lawn in front, with steps leading up to a portico, and behind a large orchard and meadow. The blinds were already down, but in several of the windows lights showed, and the place looked well kept up.
It differed but little from hundreds of other old-fashioned houses in the country, but it evidently held considerable attraction for Ray, because as we passed beyond the gates, and out of sight of any one in the house, he took out his electric torch and carefully examined the muddy roadway.
"See!" he exclaimed, pointing to tracks that ran in and out of the gateway. "The car's home is here!"
"What car?"
"The car which used to meet the German maid at Metfield," was his matter-of-fact reply. "For the present we know sufficient. We must look sharp if we are to be in Beccles before eight. If we're not there before, it will be of no use."
So we hurried back to our own car, and our driver, by taking a by-path, brought us out upon the main road again at Thorpe Market, and just after half-past seven we pulled up before the hotel in the old Suffolk market town of Beccles, under the shadow of the stumpy square old church tower.
The car was garaged, and after a drink we went forth for a walk along the quiet old-world streets, until suddenly upon a corner we came to the post office, a large old-fashioned two-storied house with steep tiled roof.
"Wait about here," my companion said; "a dark-haired man in a light grey overcoat and golf-cap will probably come to post a letter just before eight. He has a dark brown beard, and usually wears a white muffler. When he comes follow him, and see where he goes. He may know me, so I must keep out of sight."
Therefore I lit my pipe, and idled up and down, keeping the letter-box in view. In the window, directly above it, was a clock which showed it then to be a quarter to eight. I took a pretended interest in the small shops near, until about four minutes to the hour a closed motor-car swung round from the direction of the Public Hail, and pulled up before the post office.
From it two men alighted one a youngish fair-haired man, and the other, dark-bearded and much older, wore a thick grey overcoat and a white muffler. He was the man of whom I was in search.
I entered the office directly after the pair, on pretence of buying stamps, but already the elder of the two had handed in a letter to be registered, the address of which I failed to discern.
Both seemed to be in a great hurry, for as soon as the receipt was written out they re-entered the car and drove back in the direction they had come, leaving me standing helpless on the opposite side of the road.
Immediately I returned to the hotel where Ray was waiting, and reported to him, whereupon he seized his hat, and walking with me back to the post office halted in the centre of the road examining the wheel-tracks, which were still quite plain upon the damp roadway.
Then, as he walked back, he said:
"Do you know, Jack, that this town Beccles has been decided upon by the Germans as the head-quarters of the Army Corps which lands at Weybourne? It's a natural position, standing upon high ground and commanding the whole of the surrounding country. Signals made from that church tower yonder could be seen very far afield."
Then, as we sat together in the coffee-room of the hotel, eating a hasty meal, he remarked:
"We'll go back to Cromer to-night, but I shall go to town to-morrow. You'll wait till my return, won't you?"
So I was left alone for nearly a week; and on his return he announced that we must at once shift our quarters to Lowestoft. So south we went that same night, arriving at midnight, and putting up at the many-balconied Empire Hotel.
The town interested my companion not at all, but from there we went forth each day on long motor excursions, scouring the whole country as far south as Aldborough and as far west as Bury St. Edmunds. All the roads round Southwold, Bungay, Saxmundham, Stow Market, and many other towns we reconnoitred, apparently always with the same object to discover wheel-tracks of a mysterious car.
The garages of every town Ray visited alone, but his inquiries always met with the same negative result.
Late one afternoon, however, when on the road between Wymondham and Diss, he suddenly shouted to the driver to stop, and jumping out, examined the track of wheels. The road, however, was hard at that spot, and it was some time before he could decide whether the car had travelled north or south.
"They've gone north!" he declared with satisfaction; therefore we continued to follow them towards Wymondham, where they had drawn up at the "Old Green Dragon," and gone forth again, striking into a by-road which led to Bracon Ash.
"Ha!" he cried, when he saw this, "so they're busy at work that's plain!"
But by this time the light had faded, and much to our chagrin we were again compelled to give up the hunt, and find our way over by Hempnall, and so through Bungay back to Lowestoft.
Next day we were early back again at the spot, but heavy rain had unfortunately fallen all night, so the tracks had been obliterated.
After another week of unsuccessful journeying we were, one day, about half-way between Norwich going towards Aylsham, when my friend's keen eyes caught sight of a wheel-track coming out of a narrow by-road.
We halted, and descending he examined them minutely, declaring that they were what we were in search of, and quite fresh.
Therefore, considerably excited, we were soon upon the trail, following the car through Aylsham and North Walsham until, on the road that led towards the sea at Happisburgh, it suddenly turned into another byway.
Here Ray decided to pull up and follow on foot, which we did for nearly two miles, until we saw before us the railway line which runs between North Walsham and Yarmouth. We had left the road, for there, pulled up before us, was the car I had seen at Beccles, and on ahead were the two men, one of whom I recognised by his grey coat and white muffler.
