At the Rectory Roddy sat in his own wireless-room until far into the night, fitting a complete wireless receiving-set into a small cigar-box. The one he had fitted into a tin tobacco-box was efficient in a sense, but the detector being a crystal it was not sufficiently sensitive to suit him.
The one he was constructing was of his own design, with three valves—as the little wireless glow-lamps are called—the batteries and telephones being all contained in the box, which could easily be carried in the pocket together with a small coil of wire which could be strung up anywhere as an aerial, and as “earth” a lamp post, a pillar-box, or running water could be used.
It was nearly three o’clock in the morning before he had finished assembling it, and prior to fixing it in the box he submitted it to a test. Opening the window of his wireless-room he threw the end of the coil of wire outside. Then going out into the moonlight, he took the ball insulator at the end of the wire and fixed it upon a nail he had driven in the wall of the gardener’s potting-shed some time before.
Then, having stretched the wire taut to the house, he went back and attached it to one of the terminal screws of the little set upon which he had been working for many days. The earth-wire of his experimental set he joined up, and then putting on the ’phones listened intently.
Not a tick!
He slowly turned the ebonite knob of the condenser, but to no avail. Raising the wavelength brought no better result. Was it yet another failure? As an experimenter in radio he was used to failures, so it never disheartened him. Failure in prospecting was the same as failure in wireless. He received each rebuff complacently, but with that air of dogged perseverance of which success is ever born.
“Strange!” he remarked aloud. “It certainly should give signals.”
Then he examined the underside of the sheet of ebonite on which the various units were mounted, valves, condensers, etc, when at last he discovered a faulty connexion on the grid-leak. The latter will puzzle the uninitiated, but suffice it to say that so delicate is wireless receiving that over a line drawn by a lead pencil across paper or ebonite with a two-inch scratch in it filled with pencil dust the electric waves will travel. The connexion was not complete at one end. He tightened the little terminal, and suddenly came the expected high-pitched dots and dashes in the Morse code.
“Ah! Stonehaven!” he remarked. Then, by turning the knob of the condenser, a sharp rippling sound was brought in—the automatic transmission from Cologne to Aldershot at seventy words a minute.
Backwards and forwards he turned the condenser, and with a second knob altered the wavelength of his reception, first tuning in ships in the Channel signalling to their controlling station at Niton, in the Isle of Wight, or the North Foreland; then Leafield, in Oxfordshire, could be heard transmitting to Cairo, while Madrid was calling Ongar, and upon the highest wavelength the powerful Marconi station at Carnarvon was sending out a continuous stream of messages across the Atlantic.
Suddenly, as he reduced his wavelength below six hundred metres, he heard a man’s deep voice call:
“Hulloa, 3.V.N. Hulloa! This is 3.A.Z. answering. What I said was the truth. You will understand. Tell me that you do. It is important and very urgent. 3.A.Z. changing over.”
Who 3.A.Z. was, or who 3.V.N., Roddy did not at the moment know without looking up the call-letters in his list of experimental stations. The voice was, however, very strong, and evidently high power was being used.
He listened, and presently he heard a voice much fainter and evidently at a considerable distance, reply:
“Hulloa, 3.A.Z. This is 3.V.N. answering. No, I could not get you quite clearly then. Remember, I am at Nice. Kindly now repeat your message on a thousand metres. 3.V.N. over.”
Quickly Roddy increased his wavelength to a thousand metres, which he swiftly tested with his wave-metre, a box-like apparatus with buzzer and little electric bulb. Suddenly through the ether came the words even more clearly than before:
“Hulloa, 3.V.N. at Nice! Hulloa! This is 3.A.Z. repeating. I will repeat slowly. Please listen! 3.A.Z. repeating a message. Andrew Barclay leaves London to-morrow for Marseilles, where he will meet Mohamed Ben Azuz at the Hôtel Louvre et Paix. Will you go to Marseilles? Please reply. 3.A.Z. over.”
Roddy held his breath. Who could possibly be warning somebody in the south of France of his friend Barclay’s departure from Victoria to interview the Moorish Minister of the Interior regarding the concession?
Again he listened, and yet again came the far-off voice, faint, though yet distinct:
“3.V.N. calling 3.A.Z.! Thanks, I understand. Yes. I will go by next train to Marseilles. Is Freda coming? 3.V.N. over.”
“Yes. Freda will come if you wish it,” replied the loud, hard voice. “3.A.Z. calling 3.V.N. Over.”
“Hulloa, 3.A.Z. From 3.V.N. Thanks. Shall expect Freda, but not by same train. Tell Jimmie to be on the alert. I’ll explain to Freda when I see her. Good-night, old man. Good-bye. 3.V.N. closing down.”
Quickly Roddy searched his list of amateur call-signs, but he could not find either 3.A.Z. or 3.V.N. They were evidently false signs used by pre-arrangement, but by persons who, strangely enough, knew of his friend Barclay’s journey on the morrow!
And Freda? Could it be Freda Crisp who had been indicated? Why was she going south also—but not by the same train?
After an hour’s sleep young Homfray, much mystified, rose, dressed, and taking out his motorcycle, started up the long high road to London.
On the platform at Victoria as early as half-past eight o’clock he awaited his friend Barclay. Presently he came, a ruddy, round-faced, rather short little man of fifty, who was a thoroughgoing cosmopolitan and who had dabbled in concessions in all parts of the world.
“Hulloa, Homfray!” he exclaimed, looking at the muddy condition of his friend’s motor clothes. “I didn’t expect you to come to see me off.”
“No,” replied the young man rather hesitatingly, “but the fact is I have come here to warn you.”
“Warn me! Of what?” asked his friend in surprise.
Then Roddy explained, and repeated what the mysterious voice from the void had said.
“Both speaker and listener were disguised under false call-signs,” he went on. “Hence it is highly suspicious, and I felt it my duty to tell you.”
Andrew Barclay was puzzled. The porter was placing his bags in a first-class compartment of the boat train, which was crowded with people going holiday-making abroad. Loud-voiced society women commanded porters, and elderly men stalked along to the carriages following their piles of baggage. The eight-forty Paris service is usually crowded in summer and winter, for one gets to Paris by five, in time for a leisurely dinner and the series of trains which leave the Gare de Lyon in the region of nine o’clock.
“Just repeat all you said, Roddy, will you?” asked the man in the heavy travelling coat.
The young fellow did so.
“Freda? That’s a rather unusual name. Has it anything to do with that woman Freda Crisp you told me about? What do you think?”
“I believe it has.”
Barclay was aware of all the strange experiences of the shrewd young mining engineer. Only three days after his return to Little Farncombe he had gone down to the quiet old country rectory and listened to his friend’s story.
In this concession to work the ancient mines in the Wad Sus he was equally interested with his young friend in whom he believed so implicitly, knowing how enthusiastic and therefore successful he had been in his prospecting expeditions up the Amazon.
The big portable luggage-vans—those secured by wire hawsers which are slung on to the mail-boat and re-slung on to the Paris express—had been locked and sealed with lead, as they always are. The head guard’s whistle blew, and Barclay was about to enter the train, when Roddy said:
“Do take care! There’s more in this than either of us suspect. That woman Crisp! Beware of her. You will see her in due course at your hotel. Be careful. Good-bye—and good luck!”
The train moved out around the bend. The young fellow in his wet, muddy overalls stood for a moment gazing at the rear van. Should he watch for the departure of the woman? No. She might see him. Better that he should remain in apparent ignorance. So he went out, remounted his cycle, and headed away back over Putney Bridge and through crooked Kingston, Cobham, and down the steep hill in Guildford towards home.
Freda! That name was burned into his brain like the brand of a red-hot iron. Freda—the woman who had held him beneath her strange, inexplicable spell during his bondage at the remote old country house near Welwyn.
But why? Why should his father have warned him against her? His father, a most honest, upright, pious man to whom he had always looked for leadership—the road-builder to the perfect life, as he had always regarded him. No man in the world is perfect, but Norton Homfray had, to say the least, tried to live up to the standard laid down by the Holy Writ.
Had he had faults in his past life, his son wondered? Every man has faults. Were those faults being concealed by his father—the “pater” upon whom he doted and to whom when away he wrote so regularly, with all his most intimate news, though mails might leave very intermittently, as they do from the back of beyond, where prospectors carry on their work with hammer and microscope.
Then, as he rode along in the grey, damp winter morning, he reflected.
The whole situation was most puzzling. He loved Elma with a fierce all-consuming affection. She was his only beacon in his eager, strenuous life.
A week went by. He anxiously awaited news from Andrew Barclay, but the latter sent no word. He was, without doubt, negotiating with the Moorish Minister of the Interior, who was at that moment visiting France, and who was his personal friend.
But Roddy could not rid himself of the recollection of that strange conversation by radio-telephone—the request that Freda should go south. He had taken another journey out to Welwyn in order to ascertain if the woman was still at Willowden, but had found the house still closed and apparently without a caretaker. Had he been able to get a view of the back of the premises he would, no doubt, have noticed the well-constructed wireless aerial, but it was completely hidden from the road, and as during his enforced sojourn in the place he had never seen it, he remained in ignorance of its existence.
At Farncombe Towers Mr Sandys, when he returned home, had expressed himself highly delighted with the wireless set which the rector’s son had installed, and on two successive evenings sat with Elma intensely interested in listening to broadcasted concerts and news.
Three nights later Elma and her father, having been to the first night of a new revue, had had supper at the Savoy, and passing into the lounge, sat down to their coffee, when an elderly, clean-shaven, rather tall man, accompanied by a well-dressed, shorter, but good-looking companion, both in well-cut evening clothes, suddenly halted.
“Hulloa, Harrison!” exclaimed the grey-bearded financier to the man who bowed before Elma and greeted her.
“Not often we see you here, Mr Sandys!” replied the man, evidently surprised. Then he begged leave to introduce his companion, Mr Rex Rutherford.
Elma smiled as the stranger expressed delight at meeting her father and herself.
“Your name is very well known to me, as to everybody, Mr Sandys,” said the dark-eyed man pleasantly, as they both took chairs which the financier offered them, at the same time ordering extra coffee. “Though I’m an American, I live mostly in Paris, and I met your partner, Sir Charles, there quite recently.”
“I shouldn’t have thought you were an American,” remarked Elma. “We in England expect every United States citizen to speak with an accent, you know.”
“Well, Miss Sandys, I suppose I’m one of the exceptions. My father and mother were British. Perhaps that accounts for it,” he laughed, lighting a cigar.
“Mr Rutherford is more of a Parisian than American, Miss Sandys,” declared the man, Bertram Harrison. And then they began to chat about the new revue, which Elma described enthusiastically as a great success, while Rex Rutherford sat listening to her, evidently filled with admiration of her sweetness and remarkable beauty.
Elma presently inquired of Mr Harrison if he had seen Mrs Crisp lately.
“No. She’s gone to Switzerland,” was his reply.
“I’m thinking of going across to Florida very soon to spend the winter at Palm Beach. I was there last year,” remarked Rutherford. “Ever been there, Mr Sandys?”
“Never,” replied Elma’s father. “I must try it one winter. I’ve heard so much about it. Are you in London for long?”
“Only for a week or so on a matter of business. I’m at the Carlton, but I expect very soon to get back to Paris again.”
And so the conversation drifted on, both men well-bred and of charming manner, until the lights were lowered as sign that the restaurant was closing.
The pair saw Mr Sandys and his daughter into their limousine, and then walked together along the Strand.
“Well, how did it work?” asked the man Harrison eagerly.
“Excellent,” declared Gordon Gray, for it was he who had been introduced as Rex Rutherford. “We’ve taken a step in the right direction to-night. It only shows you what can be done by watchfulness. But, oh! the girl! Lovely, isn’t she?”
“Yes, but I hope, my dear Gordon, you’re not going to lose your head to a woman! We’ve other fish to fry with the old man—remember!”
“Lose my head to a woman!” cried Gray, halting beneath the street lamp and looking at him with his dark eyes. “No, my dear fellow, I never do that. It’s the woman who loses her head to me! You told me once that she dances well, didn’t you? Well, the day will come when she will dance to any tune that I choose to play!”
