The Baron looked at his watch and gave a guttural exclamation of disappointment. "Well, I really can wait no longer. You can imagine that things are moving at present in Carlton Terrace and that we have all to be at our posts. I had hoped to be able to bring news of your great coup. Did Altamont name no hour?"

A. von Bork pushed over a telegram.

Will come without fail tonight. and bring new sparking plugs.

ALTAMONT.

"Sparking plugs, eh?"

"You see he poses as a motor expert and I keep a full garage. In our code everything likely to come up is named after some spare part. If he talks of a radiator it is a battleship, of an oil pump a cruiser, and so on. Sparking plugs are naval signals."

"From Portsmouth at midday," said the secretary, examining the superscription. "By the way, what do you give him?"

"Five hundred pounds for this particular job. Of course he has a salary as well."

"The greedy rogue. They are useful, these traitors, but I grudge them their blood money."

"I grudge Altamont nothing. He is a wonderful worker. If I pay him well, at least he delivers the goods, to use his own phrase. Besides he is not a traitor. I assure you that our most pan-Germanic Junker is a sucking dove in his feelings towards England as compared with a real bitter Irish-American"

"Oh, an Irish-American?"

"If you heard him talk you would not doubt it. Sometimes I assure you I can hardly understand him. He seems to have declared war on the King's English as well as on the English king. Must you really go? He may be here any moment."

"No. I'm sorry, but I have already overstayed my time. We shall expect you early tomorrow., and when you get that signal book through the little door on the Duke of York's steps you can put a triumphant finis to your record in England. What! Tokay!" He indicated a heavily sealed dust-covered bottle which stood with two high glasses upon a salver.

"May I offer you a glass before your journey?"

"No, thanks. But it looks like revelry."

"Altamont has a nice taste in wines, and he took a fancy to my Tokay. He is a touchy fellow and needs humoring in small things. I have to study him, I assure you."

They had strolled out on to the terrace again, and along it to the further end where at a touch from the Baron's chauffeur the great car shivered and chuckled. "Those are the lights of Harwich, I suppose," said the secretary, pulling on his dust coat. "How still and peaceful it all seems. There may be other lights within the week, and the English coast a less tranquil place! The heavens, too, may not be quite so peaceful if all that the good Zeppelin promises us comes true. By the way, who is that?"

Only one window showed a light behind them; in it there stood a lamp, and beside it, seated at a table, was a dear old ruddy-faced woman in a country cap. She was bending over her knitting and stopping occasionally to stroke a large black cat upon a stool beside her.

"That is Martha, the only servant I have left."

The secretary chuckled. "She might almost personify Britannia," said he, "with her complete self-absorption and general air of comfortable somnolence. Well, au revoir, A. von Bork!"

With a final wave of his hand he sprang into the car, and a moment later the two golden cones from the headlights shot forward through the darkness. The secretary lay back in the cushions of the luxurious limousine, with his thoughts so full of the impending European tragedy that he hardly observed that as his car swung round the village street it nearly passed over a little Ford coming in the opposite direction.

A. von Bork walked slowly back to the study when the last gleams of the motor lamps had faded into the distance. As he passed he observed that his old housekeeper had put out her lamp and retired. It was a new experience to him, the silence and darkness of his widespread house, for his family and household had been a large one. It was a relief to him, however, to think that they were all in safety and that, but for that one old woman who had lingered in the kitchen, he had the whole place to himself.

There was a good deal of tidying up to do inside his study and he set himself to do it until his keen, handsome face was flushed with the heat of the burning papers. A leather valise stood beside his table, and into this he began to pack very neatly and systematically the precious contents of his safe. He had hardly got started with the work, however, when his quick ears caught the sound of a distant car. Instantly he gave an exclamation of satisfaction, strapped up the valise, shut the safe, locked it, and hurried out on to the terrace. He was just in time to see the lights of a small car come to a halt at the gate. A passenger sprang out of it and advanced swiftly towards him, while the chauffeur, a heavily built, elderly man with a gray mustache, settled down like one who resigns himself to a long vigil.

"Well?" asked A. von Bork eagerly, running forward to meet his visitor.

For answer the man waved a small brown-paper parcel triumphantly above his head. "You can give me the glad hand tonight., mister," he cried. "I'm bringing home the bacon at last."

"The signals?"

"Same as I said in my cable. Every last one of them, semaphore, lamp code, Marconi – a copy, mind you, not the original. That was too dangerous. But it's the real goods, and you can lay to that." He slapped the German upon the shoulder with a rough familiarity from which the other winced.

"Come in," he said. "I'm all alone in the house. I was only waiting for this. Of course a copy is better than the original. If an original were missing they would change the whole thing. You think it's all safe about the copy?"

The Irish-American had entered the study and stretched his long limbs from the armchair. He was a tall, gaunt man of sixty, with clear-cut features and a small goatee beard which gave him a general resemblance to the caricatures of Uncle Sam. A half-smoked, sodden cigar hung from the corner of his mouth, and as he sat down he struck a match and relit it. "Making ready for a move?" he remarked as he looked round him. "Say, mister," he added, as his eyes fell upon the safe from which the curtain was now removed, "you don't tell me you keep your papers in that?"

"Why not?"

"Gosh, in a wide-open contraption like that! And they reckon you to be some spy. Why, a Yankee crook would be into that with a can-opener If I'd known that any letter of mine was goin' to lie loose in a thing like that I'd have been a mug to write to you at all."

"It would puzzle any crook to force that safe," A. von Bork answered. "You won't cut that metal with any tool."

"But the lock?"

"No, it's a double combination lock. You know what that is?"

"Search me," said the American.

"Well, you need a word as well as a set of figures before you can get the lock to work." He rose and showed a double radiating disc round the keyhole. "This outer one is for the letters, the inner one for the figures."

"Well, well, that's fine."

"So it's not quite as simple as you thought. It was four years ago that I had it made, and what do you think I chose for the word and figures?"

"It's beyond me."

"Well, I chose August for the word, and 1914 for the figures, and here we are."

The American's face showed his surprise and admiration. "My, but that was smart! You had it down to a fine thing."
