"a.s.suming that he has in his possession facts or mechanisms that would give to one nation such stupendous advantages over the others as he claims, we must not forget that the United States has had these facts and mechanisms for some time. Therefore, it would be ill-advised to detain him forcibly, for the United States' answer to this would be a declaration of war in which the superiority of her position would be overwhelming.

"I'm inclined to believe that the reason he does not wish to sell his discovery is because he has not obtained permission from his Government to do so. They intend to dispose of it to the country with whom they can make the most favourable bargain. I think indeed that under all circ.u.mstances the best policy for this Government is to treat this man with the greatest possible consideration. If he has the power to do us harm, we must put him in such a position that he will not wish to do it; and if he has not, our treatment of him will have a tendency to draw the United States nearer to us than she is at present. We must, at least, pretend to take the American Secretary of State at his word. Whereas I do not think that there is any doubt that America is influenced entirely by selfish motives, she is now our friend, and as long as this war goes on it is to the interest of Great Britain to keep her so."

"A very good idea, Sir Egbert," agreed Underhill. "That is absolutely the only way to deal with this man. He says that he is almost a pure Anglo-Saxon, you know, and he is as proud of it as if he were an Englishman. He is the ninth in direct line from the original old chap, or rather young chap, who went from England to Virginia in 1642. Think of it! Say what you may, blood is thicker than water. That fellow is at heart an Englishman; he has been away from home nearly three hundred years."

Graves gave a little bow of comprehension. "When Mr. Edestone calls on me tomorrow," he said, "I shall not even touch on the question of the purchasing of this alleged invention, but shall offer to facilitate in every way his mission as peacemaker. I shall take him at his word that he does not intend to sell to any one, and try to persuade him that, if he is bent on coercing any people, the English are not the ones that require this, as they are in perfect accord with him, and that he would accomplish his purpose much more quickly if he would bring force to bear upon the German Emperor."

"But, Sir Egbert," broke in Underhill excitedly, "he says that he wants us to authorize him to open peace negotiations with the Kaiser, and I think he rather intimated that if we should refuse he would use force, which of course means the United States."

"Well upon my word!" Rockstone's eyes flashed, and an indignant expression took the place of the rather bored look with which he had been listening. "That is pretty strong language to use to His Imperial Majesty's Government, and for my part I think that this young gentleman and his little trick box should be shipped back home with a very polite but emphatic note to the effect that when England wishes the good offices of the United States in bringing this war to a close, she will call for them. As to the young man himself, I should say to him that if he were caught trying to get into Germany he would be looked upon as a spy endeavouring to render a.s.sistance to the enemy, and would be treated accordingly."

"But wait a moment, Rockstone," said Sir Egbert. "You are forgetting that this Mr. Edestone is in some measure at least the representative of his country. We cannot afford to offend the United States of America, even though his manners are bad."

"To the contrary," muttered Underhill, "his manners are surprisingly good."

Sir Egbert slightly inclined his head in acknowledgment of the correction. "There is the point too," he went on, "as to whether or not he is an impostor. If he is, why should we allow the American comic papers to put us in the same category with their own Secretary of State, at whom they have been poking fun for years, when they discover that this exceedingly clever young man has taken us in also?

"No, no, to me the matter seems very simple. Uncle Sam has got something he wants to sell. Good or bad it makes no difference; he wants to sell, and sell it he will to the highest bidder. Why refuse to consider his offer on the one hand, or why appear to be too anxious to close with him on the other? Let him offer it to the enemy; he will certainly come back for our bid before closing with them."

"Do you know, Sir Egbert," Lord Rockstone somewhat reluctantly allowed himself to be won over, "since you put it that way I think that perhaps you are right. Diplomacy is probably the strongest weapon with which to deal with this young man. He did not impress me as one to be easily bluffed by show of force."

"Nor should I be bluffed, even by you, Rockstone," said Underhill somewhat ruefully, rubbing his arm, "if I had the power that this chap has locked up in that little rubber box and stored away in that long head of his."

"Well, let us make a decision: does His Majesty go to Washington or shall the Chautauqua lecturer extend his professional tours to include London?" Graves gave his sly secretive laugh. Then as if ashamed of his momentary levity, and changing his entire manner, he said: "Well, gentlemen, what do you propose?"

"I rather think we are unanimous," said Underhill, "in considering that Mr. Edestone should be given a fair hearing. The final answer to his proposition can be given, of course, only after it has been discussed in full cabinet."

"That would perhaps be the best way to leave the matter," approved Rockstone.

"We are agreed then, it seems," said Graves, and they left together for Buckingham Palace.

CHAPTER VIII

THE SPY-DRIVEN TAXI

On coming out of the Admiralty, Edestone, a trifle preoccupied, was about to take the taxi with the rather sleepy driver which stood at the head of the line. But the thought came to him, where shall I go?

As he had told Rebener, none of his pals were in town and he had absolutely nothing to do until dinner at eight o'clock. Why not take lunch at some quiet little place in the neighbourhood?

"I say, cabby, is there any sort of a decent restaurant around here where one can get a very nice little lunch?"

"Yes, sir, thank you, sir"; the chauffeur rather abruptly came into full possession of his faculties. "There is a very neat little place right across the road, sir, thank you, sir," and he pointed in the direction of the window at which Schmidt was sitting.

"Ah, thank you, cabby," said Edestone in his usual kind manner with people of that cla.s.s. He was rather struck by the handsome face of the man, although it was covered over with grease and grime. "Here is a shilling. Don't you think I might be able to walk that far this beautiful day?"

"Yes, sir, thank you, sir." The man showed no appreciation of the humour. "Would you be wanting a cab later on, sir? If so I'll just hang about, sir. Times is hard in these war times, sir."

"Certainly, wait by all means," said Edestone with a jolly laugh. "Set your clock. Now open your door and drive me to that restaurant over there, and then wait for me till I have had my lunch. By the time that I get through with you I think you will find that you have done a good day's work."

"I am sure of it, sir." The chauffeur hid a surrept.i.tious chuckle with his very dirty hand.

On entering the restaurant the first person Edestone saw was Schmidt, and he gave a little nod of recognition.

"Well, Mr. Schmidt, we seem to be meeting quite often this morning. I hope that I am to infer from your presence that I will be able to get some of your delightfully greasy German dishes."

But at this point he was interrupted by the proprietor, who came bustling up, trying to force him to take a seat at a table in another part of the room.

"German dishes?" stammered the restaurant keeper. "Not at all. That was when the place was run by Munchinger, but he went back to Germany last July, and this place is run by me, and I am a Swiss. Still, sir, if you are fond of the German dishes I think I might be able to accommodate you, sir."

"Well, suppose I leave that entirely to you. I can't by any chance get a large stein of Munchener beer?"

"No, sir, I am sorry. I can get you some French beer though, which we think is much better. You know that Admiral Fisher has got those Dutchmen bottled up so tight that they tell me the beer won't froth any more in Germany." And he burst into a roar of laughter in which he was joined by a chorus of adoring customers sitting about at the different tables.

Edestone sat down while the proprietor in person took his order to the kitchen. In a very short time, the man returned and put down before him a _gemuse suppe_, following this with _schweine fleisch, sauerkraut_, and _gherkins_--a luncheon which might have been cooked in a German's own kitchen--and set before him a gla.s.s of beer which Edestone would have sworn had not been brewed outside of the city of Munich.

The proprietor bustled about, laughing and cracking clumsy jokes with everyone who would listen to him, and his jokes seemed to Edestone to be almost as German as his beer. In this way he finally worked over to where Smith was sitting, and as he pretended to arrange something on the table whispered sharply: "Go to the lavatory."

Smith, unable to eat, sat toying with his food. He gulped his beer as if it choked him. He turned around several times to look at Edestone, but the latter after his perfunctory greeting took no further notice of him. At last, paying his check, the man walked to the rear of the restaurant and into a small, dark, badly ventilated room under the stairs. The place was so dimly lighted that he could scarcely see in front of him a wash basin, but as he was wondering what he was expected to do next he heard a voice that seemed to come from a little partially opened window that looked out into a dark ventilating shaft to the left of the basin. "Pretend to wash your hands," the voice whispered cautiously. Smith did as he was directed and found that he thus brought his left ear close to the window opening.

"Now listen," said the voice, speaking rapidly in German. "G.o.d is with the Fatherland today! 4782 has been engaged to wait. Hottenroth has telephoned that our man undoubtedly has his instrument with him. The order is for you and 4782 to get it from him this afternoon at any cost. 4782 knows what he is to do." And the window closed softly.

Smith broke out into a cold perspiration. He knew that he was looking death straight in the face, and in a twinkling his mind carried him back over his entire life. He clutched at his throat as he realized his horrible situation. His present position in the grip of this relentless but invisible master had come about so gradually that he had not realized how firmly he was caught until now it was too late. Not being borne up by the hysterical exaltation of the true-born Prussian, he resented that he should be the one selected to do this ghastly thing.

He staggered back into the restaurant where the proprietor, laying a hand upon his arm, and laughing loudly and winking as if he were telling a risque story, muttered some further directions into his ear.

"He is preparing to go now. Join him and don't leave him until--" he broke off and rushed over to Edestone who had risen from the table and was taking his hat and cane from the waiter.

"I hope, sir, you found everything perfectly satisfactory?" he bowed.

"Very nice indeed," said Edestone, handing him a half-crown. "I am glad to have discovered your place and I shall come again."

At the door he encountered Smith, who was lingering about as if waiting for him.

"Oh, Mr. Edestone," he forced himself to say, swallowing and fumbling with his mouth. "I remember when I was fixing up your Little Place in the Country for you that you took a great deal of interest in old English prints. Well, I have just found an old print shop over in the Whitechapel district with some of the most wonderful old prints, and if you have the time to spare I would like to take you over and have the old man show them to you."

"I should like to very much," said Edestone. "I have just been wondering what I should do with myself this afternoon."

"The Kaiser and G.o.d will bless you for this," the restaurant keeper whispered into Smith's ear, after he had bowed Edestone out to the sidewalk.

"Mr. Smith, will you please give the address to the driver," said Edestone as he stepped into the taxi. Smith leaned over and gave some mumbled instructions to the chauffeur, who had remained upon his box; then he took his place at the side of his friend and patron.

But no sooner had the motor started than he turned to Edestone. "Mr. Edestone,"--his voice trembled so violently that he could scarcely speak,--"please do not move or seem surprised at what I am going to say."

Edestone drew back slightly and looked at him. He thought at first that the man had suddenly lost his reason. Smith was perfectly livid and his little eyes were starting from his head. His mouth was open and he seemed to be vainly trying to draw his blue lips over his great dry yellow teeth on which they seemed to catch, giving him the appearance of a snarling dog as he cringed in the corner of the cab. One hand was pulling at his collar while with the other he clutched at the seat in a vain effort to restrain the tremors which were shaking him from head to foot. "Don't speak. I must talk and talk fast," he said.

Edestone leaned forward as if to halt the car, but the fellow caught him by the knee in a grip almost of desperation.
