The first few seconds after the entrance of the two men were monopolised by the greetings of Pamela with her brother. Fischer stood a little in the background, his eyes fixed upon Lutchester. His brain was used to emergencies, but he found himself here confronted by an unanswerable problem.

"Say, this is Mr. Lutchester, isn't it?" he inquired, holding out his hand.

"The same," Lutchester assented politely. "We met at Henry's some ten days ago, didn't we?"

"Mr. Lutchester has brought us a letter from Dicky Green, Jimmy," Pamela explained, as she withdrew from her brother's arms. "Quite unnecessary, as it happens, because I met him in London just before we sailed."

"Very glad to meet you, Mr. Lutchester," Jimmy declared, wringing his hand with American cordiality. "Dicky's an old pal of mine—one of the best. We graduated in the same year from Harvard."

Conversation for a few minutes was platitudinous. Van Teyl, although he showed few signs of his recent excesses, was noisy and boisterous, clutching at this brief escape from a situation which he dreaded. Fischer on the other hand, remained in the back-ground, ominously silent, thinking rapidly, speculating and theorising as to the coincidence, if it were coincidence, of finding Lutchester and Pamela together. He listened to the former's polite conversation, never once letting his eyes wander from his face. All his thoughts were concentrated upon one problem. The mysterious escape of Sandy Graham, which had sent him flying from the country, remained unsolved. Of Pamela's share in it he had already his suspicions. Was it possible that Lutchester was the other and the central figure in that remarkable rescue? He waited his opportunity, and, during a momentary lull in the cheerful conversation, broke in with his first question.

"Say, Mr. Lutchester, you haven't any twin brother, have you?"

"No brother at all," Lutchester admitted.

"Then, how did you get over here? You were at Henry's weren't you, on the night the Lapland sailed? You didn't cross with us, and there's no other steamer due for two days."

"Then I can't be here," Lutchester declared. "The thing's impossible."

"Guess you'll have to explain, if you want to save me from a sleepless night," Fischer persisted.

Lutchester smiled. He had the air of one enjoying the situation immensely.

"Well," he said, "I have had to confess to Miss Van Teyl here, so I may as well make a clean breast of it to you. To every one else I meet in New York, I shall say that I came over on the Lapland. I really came over on a destroyer."

Fischer's face seemed to become more set and grim than ever.

"A British destroyer," he muttered to himself.

"It was kind of a joy ride," Lutchester explained confidentially, "a cousin of mine who was in command came in to see me and say good-by, just after I'd received my orders from the head of my department to come out here on the next steamer, and he smuggled me on board that night. Mum's the word, though, if you please. We asked nobody's leave. It would have taken about a month to have heard anything definite from the Admiralty."

"A British destroyer come across the Atlantic, eh?" Mr. Fischer muttered. "She must have come out on a special mission, then, I imagine."

"That is not for me to say," Lutchester observed, with stiff reticence.

Pamela suddenly and purposely intervened. She turned towards Fischer.

"Mr. Lutchester brought some rather curious news," she observed. "He got it by wireless. Do you remember all the fuss there was about the disappearance of Captain Holderness' friend at Henry's?"

"I heard something about it," he admitted grimly.

"Well, Captain Graham was in my party, so naturally I was more interested than any one else. To all appearance he entered Henry's Restaurant, walked up the stairs, and disappeared into the skies. The place was ransacked everywhere for him, but he never turned up. Well, the very next day he was murdered in a motor-car on his way to Northumberland."

"Incredible!" Fischer murmured.

"Seems a queer set out," Lutchester remarked, "but it's quite true. He was supposed to have discovered a marvellous new explosive, the formula for which had been stolen. He was on his way up to Northumberland to make fresh experiments."

"For myself I have little faith," Fischer observed, "in any new explosives. In Germany they believe, I understand, that the limit of destructiveness has been attained."

"The Germans should know," Lutchester admitted carelessly. "I'm afraid they are still a good deal ahead of us in most scientific matters. I will take the liberty, of calling some time to-morrow, Miss Van Teyl, and hope I shall have the pleasure of improving my acquaintance with your brother. Good night, Mr. Fischer."

"Are you staying in the hotel?" the latter inquired.

"On the fifteenth floor," was the somewhat gloomy reply. "I shan't be able to shave in front of the window without feeling giddy. However, I suppose that's America. Good-by, everybody."

With a little inclusive and farewell bow he disappeared. They heard him make his way down the corridor and ring for the lift. Rather a curious silence ensued, which was broken at last by Pamela.

"Is that," she asked, throwing herself into an easy-chair and selecting a cigarette, "just an ordinary type of a nice, well-bred, unintelligent, self-sufficient Englishman, or—"

"Or what?" Fischer asked, with interest.

Pamela watched the smoke curl from the end of her cigarette.

"Well, I scarcely know how to finish," she confessed, "only sometimes when I am talking to him I feel that he can scarcely be as big a fool as he seems, and then I wonder. Jimmy," she went on, shaking her head at him, "you're not looking well. You've been sitting up too late and getting into bad habits during my absence. Open confession, now, if you please. If it's a girl, I shall give you my blessing."

Van Teyl groaned and said nothing. A foreboding of impending trouble depressed Pamela. She turned towards Fischer and found in his grim face confirmation of her fears.

"What does this mean?" she demanded.

"Your brother will explain," Fischer replied. "It is better that he should tell you everything."

"Everything?" she repeated. "What is there to tell. What have you to do with my brother, anyway?" she added fiercely.

"You must not look at me as though I were in any way to blame for what has happened," was the insistent reply. "On the contrary, I have been very lenient with your brother. I am still prepared to be lenient—upon certain conditions."

The light of battle was in Pamela's eyes. She fought against the significance of the man's ominous words. This was his first blow, then, and directed against her.

"I begin to understand," she said. "Please go on. Let me hear everything."

Van Teyl had turned to the sideboard. He mixed and drank off a whisky and soda. Then he swung around.

"I'll make a clean breast of it in a few words, Pamela," he promised. "I've gambled with Fischer's money, lost it, forged a transfer of his certificates to meet my liabilities, and I am in his power. He could have me hammered and chucked into Sing Sing, if he wanted to. That's all there is about it."

Pamela stood the shock well. She turned to Fischer.

"How much of this are you responsible for?" she asked.

"That," he objected, "is an impotent question. It is not I who had the moulding of your brother's character. It is not I who made him a forger and a weakling."

Van Teyl's arm was upraised. An oath broke from his lips. Pamela seized him firmly and drew him away.

"Be quiet, James," she begged. "Let us hear what Mr. Fischer is going to do about it."

"That depends upon you," was the cold reply.

Pamela stood at the head of the table, between the two men, and laughed. Her brother had sunk into a chair, and his head had dropped moodily upon his folded arms. She looked from one to the other and a new sense of strength inspired her. She felt that if she were not indeed entirely mistress of the situation, yet the elements of triumph were there to her hand.

"This is living, at any rate," she declared. "First of all I discover that your Japanese servant is a spy—"

"Nikasti!" Van Teyl interrupted furiously. "Blast him! I knew that there was something wrong about that fellow, Fischer."

Fischer frowned.

"What's he been up to?" he inquired.

"Well, to begin with," Pamela explained, "he searched my room, then he locked me in here, and was proceeding to threaten me when fortunately Mr. Lutchester arrived."

"Threaten you—what about?" Fischer demanded.

"He seemed to have an absurd idea," Pamela explained sweetly, "that I might have somewhere concealed upon my person the formula which was stolen from Captain Graham last Monday week at Henry's Restaurant. It makes quite a small world of it, doesn't it?"

"I will deal with Nikasti for this," Fischer promised, "if it is true.
Meanwhile?"

"No sooner have I got over that little shock," Pamela went on, "than you turn up with this melodramatic story, and an offer from Mr. Fischer, which I can read in his face. Really, I feel that I shall hear the buzz of a cinema machine in a moment. How much do you owe him, Jimmy?"

"Eighty-nine thousand dollars," the young man groaned.

"I'll write you a cheque to-morrow morning," Pamela promised. "Will that do, Mr. Fischer?"

"It is the last thing I desire," was the calm reply.

"Really! Well, perhaps now you will come to the point. Perhaps you will tell me what it is that you do want?"

"Stolen property," Fischer announced deliberately—"stolen property, however, to which I have a greater right than you."

She laughed at him mockingly.

"I think not, Mr. Fischer," she said. "You really don't deserve it, you know."

"And why not?"

"Just see how you have bungled! You bait the trap, the poor man walks into it, and you allow another to forestall you. Not only that, but you actually allow Japan to come into the game, and but for Mr. Lutchester's appearance we might both of us have been left plantÉ lÀ. No, Mr. Fischer! You don't deserve the formula, and you shall not have it. I'll pay my brother's debt to you in dollars—no other way."

"Dollars," Mr. Fischer told her sternly, "will never buy the forged transfer. Dollars will never keep your brother out of the city police court or Sing Sing afterwards. There isn't much future for a young man who has been through it."

Van Teyl was upon him suddenly with a low, murderous cry. Fischer had no time to resist, no chance of success if he had attempted it. He was borne backwards on to the lounge, his assailant's hand upon his throat. The young man was beside himself with drink and fury. The words poured from his lips, incoherent, hot with rage.

"You—hound! You've made my life a hell! You've plotted and schemed to get me into your power!… There! Do you feel the life going out of you?… My sister, indeed! You!… You scum of the earth! You …"

"James!"

The sound of Pamela's voice unnerved him. His fit of passion was spent.
She dragged him easily away.

"Don't be a fool, Jimmy!" she begged. "You can't settle accounts like that."

"Can't I?" he muttered. "If we'd been alone, Pamela … my God, if he and I had been alone here!"

"Jimmy," she said, "you're a fool, and you've been drinking. Fetch the water bottle."

He obeyed, and she dashed water in Fischer's face. Presently he opened his eyes, groaned and sat up. There were two livid marks upon his throat. Van Teyl watched him like a crouching animal. His eyes were still lit with sullen fire. The lust for killing was upon him. Fischer sat up and blinked. He felt the atmosphere of the room, and he knew his danger. His hand stole into his hip pocket, and a small revolver suddenly flashed upon his knees. He drew a long breath of relief. He was like a fugitive who had found sanctuary.

"So that's the game, James Van Teyl, is it?" he exclaimed. "Now listen."

He adjusted the revolver with a click. His cruel, long fingers were pressed around its stock.

"I am not threatening you," he went on. "I am not fond of violence, and I don't believe in it. This is just in case you come a single yard nearer to me. Now, Miss Van Teyl, my business is with you. We won't fence any longer. You will hand over to me the pocketbook which you stole from Captain Graham in Henry's Restaurant. Hand it over to me intact, you understand. In return I will give you the forged transfer of stock, and leave it to your sense of honour as to whether you care to pay your brother's debt or not. If you decline to consider my proposition, I shall ring up Joseph Neville, your brother's senior partner. I shall not even wait for to-morrow, mind. I shall make an appointment, and I shall place in his hands the proof of your brother's robbery."

"Perhaps," Pamela murmured, "I was wrong to stop you. Jimmy….
Anything else, Mr. Fischer?"

"Just this. I would rather have carried this matter through in a friendly fashion, for reasons at which I think you can guess."

She shook her head.

"You flatter my intelligence!" she told him scornfully.

"I will explain, then. I desire to offer myself as your suitor."

She laughed at him without restraint or consideration.

"I would rather marry my brother's valet!" she declared.

"You are entirely wrong," he protested. "You are wrong, too, in holding up cards against me. We are on the same side. You are an American, and so am I. I swear that I desire nothing that is not for your good. You have wonderful gifts, and I have great wealth and opportunities. I have also a sincere and very heartfelt admiration for you."

"I have never been more flattered!" Pamela scoffed.

He looked a little wistfully from one to the other. Antagonism and dislike were written in their faces. Even Pamela, who was skilled in the art of subterfuge, made little effort to conceal her aversion. Nevertheless, he continued doggedly.

"What does it matter," he demanded, "who handles this formula—you or
I? Our faces are turned in the same direction. There is this difference
only with me. I want to make it the basis of a kindlier feeling in
Washington towards my father's country."

Pamela's eyebrows were raised.

"Are you sure," she asked, "that the formula itself would not find its way into your father's country?"

"As to that I pledge my word," he replied. "I am an American citizen."

"Looks like it, doesn't he!" Van Teyl jeered.

"Tell us what you have been doing in Berlin, then?" Pamela inquired.

"I had a definite mission there," Fischer assured them, "which I hope to bring to a definite conclusion. If you are an American citizen in the broadest sense of the word, England is no more to you than Germany. I want to place before some responsible person in the American Government, a proposal—an official proposal—the acceptance of which will be in years to come of immense benefit to her."

"And the quid pro quo?" Pamela asked gently.

"I am not here for the purpose of gratifying curiosity," Fischer replied, "but if you will take this matter up seriously, you shall be the person through whom this proposal shall be brought before the American Government. The whole of the negotiations shall be conducted through you. If you succeed, you will be known throughout history as the woman who saved America from her great and growing danger. If you fail, you will be no worse off than you are now."

"And you propose to hand over the conduct of these negotiations to me,"
Pamela observed, "in return for what?"

"The pocketbook which you took from Captain Graham."

"So there we are, back again at the commencement of our discussion," Pamela remarked. "Are you going to repeat that you want this formula for Washington and not for Berlin?"

"My first idea," Fischer confessed, "was to hand it over to Germany. I have changed my views. Germany has great explosives of her own. This formula shall be used in a different fashion. It shall be a lever in the coming negotiations between America and Germany."

"We have had a great deal of conversation to no practical purpose,"
Pamela declared. "Why are you so sure that I have the formula?"

Fischer frowned slightly. He had recovered himself now, and his tone was as steady and quiet as ever. Only occasionally his eyes wandered to where James Van Teyl was fidgetting about the table, and at such times his fingers tightened upon the stock of his revolver.

"It is practically certain that you have the papers," he pointed out. "You were the first person to go up the stairs after Graham had been rendered unconscious. Joseph admits that he had been forced to leave him—the orchestra was waiting to play. He was alone in that little room. That you should have known of its existence and his presence there is surprising, but nothing more. Furthermore, I am convinced that you were in some way concerned with his rescue later. You visited Hassan and you visited Joseph. From the latter you procured the key of the chapel. If only he had had the courage to tell the truth—well, we will let that pass. You have the papers, Miss Van Teyl. I am bidding a great price for them. If you are a wise woman, you will not hesitate."

There was a knock at the door. They all three turned towards it a little impatiently. Even Pamela and her brother felt the grip of an absorbing problem. To their surprise, it was Lutchester who reappeared upon the threshold. In his hand he held a small sealed packet.

"So sorry to disturb you all," he apologised. "I have something here which I believe belongs to you, Miss Van Teyl. I thought I'd better bring it up and explain. From the way your little Japanese friend was holding on to it, I thought it might be important. It is a little torn, but that isn't my fault."

He held it out to Pamela. It was a long packet torn open at one end. From it was protruding a worn, brown pocketbook. Pamela's hand closed upon it mechanically. There was a dazed look in her eyes. Fischer's fingers stole once more towards the pocket into which, at Lutchester's entrance, he had slipped his revolver.
